elevated wave-cut platforms in southern california are evidence that this coastal area is emergent. question 35 options: true false
True. Elevated wave-cut platforms in southern California are evidence of emergent coastlines.
Emergent coastlines are areas where the land is rising relative to sea level, causing the shoreline to retreat and the wave-cut platforms to become elevated above the current sea level. An emergent coastline is one that is gradually rising relative to sea level, either due to tectonic uplift or a drop in sea level. As the coastline rises, wave action gradually cuts into the rocky shoreline, creating a wave-cut platform at the base of the cliffs. Over time, these platforms can be uplifted and preserved above sea level, providing evidence of the coastline's history of emergence. In southern California, the wave-cut platforms are often found along the coast of the Santa Barbara Channel Islands, which have been uplifted over the past several million years due to tectonic forces. The platforms provide important information about the region's geologic history, including the timing and extent of uplift and the fluctuation of sea level over time.

The statement that "elevated wave-cut platforms in Southern California are evidence that this coastal area is emergent" is true.
Elevated wave-cut platforms, also known as marine terraces, are flat or gently sloping surfaces formed by the combined action of waves and tides eroding the coastline. They are left behind when the coastline is uplifted, indicating an emergent coastline.
Southern California's coastline has experienced a series of geological uplifts over time, which have contributed to the formation of these wave-cut platforms. The uplift is caused by tectonic forces related to the interaction of the Pacific Plate and the North American Plate along the San Andreas Fault system. This tectonic activity has caused the elevation of the coastal region in Southern California, leading to the creation of these elevated platforms.
As a result, the presence of elevated wave-cut platforms in Southern California is a clear indicator of an emergent coastline, demonstrating that the area is experiencing uplift and change over time. This geological evidence is vital in understanding the coastal processes and the dynamics of the Southern California region.

what is a spelunker likely to encounter? group of answer choices geysers granitic plutons speleothems cave bears
A spelunker is likely to encounter speleothems, as they are formations found in caves, such as stalactites and stalagmites. Geysers and granitic plutons are geological features not typically encountered in caves, and cave bears are an extinct species.
Spelunker sounds like the noise a pebble makes when you drop it down a deep hole and into dark, hidden water far below. But there's nothing dark or obscure about the etymology of the term. We borrowed "spelunker" from Latin spelunca, which in turn derives from Greek spelynx. When you get to the bottom of things, you find that both the Latin and Greek words mean "cave." Although "spelunker" might sound neat, be careful: some cave-exploring enthusiasts prefer the term "caver."

How human activities affect the quality of water in the rivers
Answer: Sulfur dioxide and nitrous oxide emitted from factories and power stations enter river systems through acid rain. Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.
Explanation:
Human beings and their activities affect the quality of rivers and harm river ecosystems.
Dams which are a human creation alter the flow of rivers. The reduced flow will then alter aquatic habitats which will remove populations of species that depend on the flow for food. Human activities pollute the rivers which lower the pH of water.
Over the last few years, the usage of pesticides has increased to a greater extent. All of these pesticides and herbicides are washed into the groundwater every time it rains. It will also funnel into the nearby rivers, lakes, and streams from where so many municipalities get their drinking water.

latitudes between the equator and ~35° have __________ incoming solar radiation than outgoing terrestrial radiation, resulting in __________.
Latitudes between the equator and ~35° have more incoming solar radiation than outgoing terrestrial radiation, resulting in a surplus of energy.
This surplus of energy leads to warmer temperatures and a generally more tropical climate in these regions. This is because the sun's rays are more direct at the equator, leading to a greater concentration of solar energy per unit area, and the atmosphere is thinner at low latitudes, allowing more solar radiation to reach the Earth's surface. As a result of this surplus of energy, areas near the equator tend to be warm and humid, while areas at higher latitudes experience cooler temperatures. This energy surplus is one of the factors that drives atmospheric circulation and the global climate system, as warm air rises near the equator and cooler air sinks at higher latitudes, creating global wind patterns and ocean currents.

A smaller volume and a larger shape cool faster. This is because a larger volume of molten rock takes longer to cool than a smaller volume, while a more compact shape will retain heat longer than a more spread-out shape, slowing down the cooling process.
When molten rock, or magma, cools and solidifies, the rate at which it cools affects the size and arrangement of the mineral crystals that form. A smaller volume of magma will cool more quickly than a larger volume, because there is less heat to dissipate. Similarly, a shape that has more surface area in contact with the cooler surroundings will cool more quickly than a shape with less surface area. The rate of cooling affects not only the size of the mineral crystals, but also their arrangement and texture, which can provide clues about the conditions under which the magma solidified. Similarly, more complex shapes have a greater surface area to volume ratio, which allows for more efficient heat transfer and faster cooling. As a result, smaller volumes of molten rock with simpler shapes will cool more quickly and form smaller crystals, while larger volumes with more complex shapes will cool more slowly and form larger crystals.

The correct answer is shale. Very fine mud sediments with a size less than 1/256 mm are classified as clay particles. When these clay particles are deposited and buried under pressure and compaction, they can form a sedimentary rock known as shale.
Shale is a fine-grained sedimentary rock composed mainly of clay minerals, such as illite, kaolinite, and smectite. The small particle size of the clay minerals allows for the formation of a dense, impermeable rock that can be found in a variety of depositional environments, including marine, lacustrine, and deltaic environments. The color of shale can vary from gray to black, and it often exhibits a fissile texture, meaning it can easily split into thin layers or sheets due to the alignment of clay minerals during compaction. Shale can also contain fossils, which can provide valuable information about the environment and conditions under which the rock was formed.

during crucial periods of human evolution, the pleistocene was characterized by group of answer choices aridity, then humidity. massive glaciation, then warm interglacials. high humidity. glaciation, then aridity.
The Pleistocene epoch, which lasted from about 2.6 million years ago to 11,700 years ago, was characterized by dramatic fluctuations in climate and environmental conditions.
One of the defining features of this period was the alternating cycles of glaciation and warming, known as glacial-interglacial cycles. During glacial periods, large portions of the earth's surface were covered by massive ice sheets, causing a drop in sea levels and a drying of many regions. Conversely, during interglacial periods, the earth's climate was relatively warmer and more humid, leading to the expansion of forests and grasslands. These climate fluctuations had a profound impact on human evolution, shaping the morphology, behavior, and distribution of early humans. During the glacial periods, early humans were forced to adapt to harsh and challenging conditions, such as limited food resources and extreme temperatures. In contrast, during the warmer interglacial periods, early humans were able to expand their ranges and take advantage of new resources, leading to the development of new cultural and technological innovations.

A) XII is the maximum possible damage designation on the Mercalli scale. The Mercalli intensity scale is a measure of the intensity of an earthquake based on the observed effects and damage caused by the earthquake at a given location.
It was developed by Italian seismologist Giuseppe Mercalli in the early 20th century as a way to standardize earthquake reporting and to better understand the impact of earthquakes on buildings and infrastructure. The Mercalli scale consists of a series of increasing levels of intensity, each with a description of the types of damage and effects that can be expected at that level. The scale ranges from I (not felt) to XII (total destruction), with each level describing a progressively more severe level of shaking and damage. At the highest end of the scale, an earthquake with a Mercalli intensity of XII would be characterized by total destruction, with buildings and infrastructure collapsing and many casualties. This level of intensity is extremely rare, and only a few earthquakes in history have been rated as XII on the Mercalli scale, including the 1906 San Francisco earthquake and the 1960 Valdivia earthquake in Chile.

an astronomer has a telescope with a diameter of 27 cm and a focal length of 250 cm. which eyepiece should he use to achieve a result closest to 140× magnification?
The astronomer should use an eyepiece with a focal length of 1.79 cm to achieve a result closest to 140x magnification.
To calculate the magnification of a telescope, we need to divide the focal length of the telescope by the focal length of the eyepiece. Therefore, the astronomer needs to find the eyepiece that will result in a magnification of 140x.
To do this, we can use the following formula:
Magnification = Telescope Focal Length / Eyepiece Focal Length
Given that the telescope has a focal length of 250 cm, we can rearrange the formula to find the eyepiece focal length needed for a magnification of 140x:
Eyepiece Focal Length = Telescope Focal Length / Magnification
Eyepiece Focal Length = 250 cm / 140
Eyepiece Focal Length = 1.79 cm
Therefore, the astronomer should use an eyepiece with a focal length of 1.79 cm to achieve a result closest to 140x magnification. It's important to note that magnification alone doesn't determine the quality of the image produced by a telescope. Other factors such as the aperture and quality of the optics also play a significant role. Nonetheless, using the correct eyepiece to achieve the desired magnification is a crucial step in astronomical observation.

use an eyepiece with a focal length closest to 1.79 cm to achieve approximately 140x magnification. calculate the magnification of a telescope, you need to divide the focal length of the telescope by the focal length of the eyepiece. So, to achieve a magnification of 140x, the astronomer would need to use an eyepiece with a focal length of:Eyepiece focal length = Telescope focal length / Desired magnification
Eyepiece focal length = 250 cm / 140x
Eyepiece focal length = 1.79 cmTherefore, the astronomer would need to use an eyepiece with a focal length of approximately 1.79 cm to achieve a magnification closest to 140x. However, it is important to note that the actual magnification achieved will depend on various factors, such as atmospheric conditions and the observer's eyesight.

what provision of the resource conservation and recovery act (rcra) is aimed at eliminating midnight dumping and ensuring proper disposal of hazardous wastes?
The provision of the Resource Conservation and Recovery Act (RCRA) that is aimed at eliminating midnight dumping and ensuring proper disposal of hazardous wastes is the "cradle-to-grave" system.
This system requires hazardous waste generators to properly label, package, and store their waste, as well as to use licensed and authorized transporters and treatment facilities for the disposal of the waste. The system also mandates that waste handlers keep detailed records of the waste from its creation to its final disposal, thereby ensuring accountability and proper handling throughout the entire waste management process. This provision is critical in preventing the illegal and hazardous practice of midnight dumping, which can harm human health and the environment.

main sequence stars, such as the sun, shine by _________ in their interiors.
Main sequence stars, such as the sun, shine by converting hydrogen into helium in their interiors.
Deep inside stars, hydrogen undergoes nuclear fusion to create helium, which powers the star. The star's central regions emit energy that powers both its illumination and the pressure required to prevent the star from collapsing under its own weight.
A star is a big ball of hot, luminous gas. Atoms of hydrogen collide in its centre to create helium and release a tremendous quantity of energy that heats the gas. This process, known as nuclear fusion, is what causes stars to shine.

Main sequence stars, such as the sun, shine by nuclear fusion in their interiors.
Nuclear fusion is the process by which atoms combine to form a heavier nucleus, releasing a tremendous amount of energy in the process. In the sun's core, hydrogen atoms are fused together to form helium, releasing energy in the form of light and heat. This process is what powers the sun and allows it to shine. The sun, like other main sequence stars, is in a state of equilibrium. The inward force of gravity is balanced by the outward pressure created by the energy released from nuclear fusion.
This balance allows the sun to maintain a stable size and temperature over millions of years. Main sequence stars follow a well-defined sequence based on their mass and temperature. The sun, as a relatively small and cool main sequence star, is in the middle of this sequence. As a main sequence star, it is primarily powered by nuclear fusion in its core and will continue to shine for several billion years before eventually running out of fuel and transitioning to a red giant star.
In conclusion, the sun and other main sequence stars shine by nuclear fusion in their interiors. This process allows them to maintain a stable size and temperature for millions of years, providing the energy that sustains life on Earth.

of the sun's energy that reaches earth's surface, what percentage is near-infrared light? oceanography
Near-infrared light (NIR) is a type of electromagnetic radiation that has a wavelength between 0.7 and 3 micrometers.
It is part of the sun's energy that reaches Earth's surface and is the most abundant form of solar radiation, making up approximately 50% of the total energy. NIR has a smaller wavelength than visible light, meaning that it is able to penetrate further into the atmosphere and the ocean before it is absorbed.
This makes it an important form of energy for many oceanographic processes, such as photosynthesis and energy transfer from the sun to the ocean. NIR is also important for the warming of the Earth's surface, as it helps to absorb and retain heat from the sun. As a result, NIR is a key component of the Earth's climate system and is a fundamental part of the energy balance of the planet.
