If the western coast of South America is experiencing unusually warm and wet weather, you would expect the weather on the eastern coast of Australia to be cooler and drier. This is due to the El Niño-Southern Oscillation (ENSO) phenomenon, which affects global weather patterns.
What is El Niño-Southern Oscillation?
El Niño-Southern Oscillation is a phenomenon that occurs when the ocean temperatures in the equatorial Pacific Ocean change from their normal temperatures. It occurs every three to seven years and lasts between one and two years.
The change in ocean temperature causes the trade winds, which usually blow from east to west, to slow down or reverse direction. When the trade winds slow down or reverse, it causes a buildup of warm water in the eastern Pacific Ocean, leading to El Niño. During an El Niño, the Pacific Ocean's warm surface waters move eastward towards South America, leading to unusually warm and wet weather on the western coast of South America.On the other hand, when the trade winds are stronger than usual, the ocean currents become stronger, leading to colder ocean temperatures in the eastern Pacific Ocean. This is known as La Niña, and it results in cooler and drier weather on the western coast of South America.
What is the effect of El Niño-Southern Oscillation on Australia?
Australia's weather patterns are also affected by El Niño-Southern Oscillation. During an El Niño event, Australia typically experiences drier and warmer weather conditions, especially in the eastern parts of the country. However, during a La Niña event, Australia typically experiences wetter and cooler weather conditions.El Niño-Southern Oscillation is a significant weather phenomenon that affects global weather patterns, including the weather on the eastern coast of Australia. If the western coast of South America is experiencing unusually warm and wet weather, you would expect the weather on the eastern coast of Australia to be cooler and drier.

the annual cycle of prevailing weather conditions at a given place based on long-term contitions is known as: weather. a trend cyclone climate global warming
The annual cycle of prevailing weather conditions at a given place based on long-term conditions is known as climate.
The term weather is used to refer to short-term conditions such as precipitation, temperature, and wind. The climate of a region is determined by a variety of factors, including latitude, elevation, prevailing winds, and the presence of land and water bodies.
It can be classified into different categories based on temperature, precipitation, and other factors. In general, climate change refers to long-term changes in weather patterns and temperature around the world, while global warming refers specifically to the gradual warming of the planet's surface due to increased levels of greenhouse gases in the atmosphere. Cyclones, on the other hand, are severe tropical storms that can cause significant damage and loss of life. Trends are statistical measurements of changes over time. The correct answer is "climate."

which kind of seismic wave is responsible for the most shaking (and thus, the most damage to human structures)?
The body waves and surface waves responsible for the most shaking.The seismic wave responsible for the most shaking (and thus, the most damage to human structures) is the surface wave.
What are seismic waves?Seismic waves are waves that are generated by earthquakes and other disturbances in the Earth's surface, such as explosions, volcanic activity, and landslides.
They are made up of various types of waves, each with its own distinctive characteristics. There are two types of seismic waves: body waves and surface waves.
Body waves are seismic waves that travel through the Earth's interior. P-waves and S-waves are two types of body waves. Surface waves, on the other hand, are seismic waves that travel along the Earth's surface.
Rayleigh waves and Love waves are two types of surface waves.
Surface waves are responsible for the most shaking (and thus, the most damage to human structures).
The reason for this is that they travel more slowly than body waves, which allows them to cause more sustained shaking.
They are also more complex than body waves, which can cause them to interact with the Earth's surface in unpredictable ways that can lead to more intense shaking.

what is an aquifer, igneous and metamorphic rocks are not good aquifers as they contain little natural porosity or permeability.
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted. Igneous and metamorphic rocks generally contain little natural porosity or permeability and therefore cannot be used as aquifers. Igneous rocks, for instance, form when molten magma cools and solidifies.
The cooling process does not leave much space for porosity and permeability. The recrystallization of the rock grains during metamorphism also does not leave much space for porosity and permeability.
Aquifers can be found in sedimentary rocks like sandstone, limestone and shale because the grains of these rocks are arranged in a way that allows for more porosity and permeability.

an example of a primary effect of drought is question 15 options: a drop in groundwater levels rolling blackouts a decrease in tourism low dissolved oxygen content in reservoirs
An example of a primary effect of drought is a drop in groundwater levels.
When droughts occur, one of the most common outcomes is a drop in groundwater levels. As the amount of precipitation drops, the amount of water that enters the soil also drops, resulting in a decrease in groundwater levels. As groundwater levels decline, it becomes more challenging to access enough water to meet the needs of communities and agriculture.
As a result, water scarcity becomes an increasingly serious issue.
Therefore, a drop in groundwater levels is a primary effect of drought. Rolling blackouts, a decrease in tourism, and low dissolved oxygen content in reservoirs are all secondary effects of drought.
Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water shortage. Drought can have a serious impact on health, agriculture, economies, energy and the environment.

As the river approaches sea level, the gradient ______.
As the river approaches sea level, the gradient decreases.
The gradient of a river is defined as the slope or steepness of the river. It is usually expressed in terms of the river's elevation changes per unit distance. When a river's gradient is steep, the river flows faster and carries more sediment. As a river flows from its source to its mouth, its gradient decreases.
When a river reaches its mouth, it is at sea level and its gradient is extremely gentle. The gradient of a river determines its erosional power, transport capacity, and deposition capacity.

does the change of environment from the base of the section up to the thick gray shale indicate an advance (transgression) or retreat (regression) of the sea?
The change of environment from the basal conglomerate to the thick gray shale indicates a transgression of the sea, as smaller clast size suggests a deeper marine environment.
During a transgression, sea level rises, leading to the inundation of previously exposed land areas. As the sea advances, the environment changes from terrestrial to marine, and sediments deposited also change from coarser to finer-grained.

Chemical reactions in the water and aliens are not significant sources of sediment on the continental shelf. The correct option is d.
Most sediment on the continental shelf is derived from erosion on the continent.
What is the continental shelf?The shallow oceanic area is known as the continental shelf.
It is located next to the shore and extends from the shore to the continental slope.
The water depth in the continental shelf ranges from 100 meters to 200 meters, depending on the location, and the slope of the shelf ranges from 0.1 to 1 degree.
The main source of sediment on the continental shelf is erosion on the continent.
When rocks and soil are exposed to the elements, such as wind, rain, and temperature fluctuations, they begin to erode.
This can result in sediment that is transported by rivers to the ocean and deposited on the continental shelf.
Other sources of sediment on the continental shelf include volcanic eruptions, underwater landslides, and other natural events.
Life in the sea is also a source of sediment, as organisms such as corals and clams produce shells and other materials that eventually break down and contribute to the sediment on the sea floor.
