How can biological weathering result in chemical erosion?
Roots loosen soil and break rocks.
Large herds trample rocks and break up soil.
Plants transpire water vapor.
Bacteria release acids and other agents that break down rock.
Answer: Biological weathering only refers to weathering caused by organisms -- animals, plants, fungi and microorganisms such as bacteria. While certain forms of biological weathering, such as the breaking of rock by tree roots, are sometimes categorized as either physical or chemical, biological weathering can be either physical or chemical

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.
Define Natural Selection. Explain with an example.
Answer:
Natural selection is to ensure that only the best individuals live. Natural selection does not allow the sick or the incapacitated to survive. But man does not have natural selection, only in some cases. There is also little natural selection on farms.
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds, evolving long necks has enabled giraffes to feed on leaves that others can't reach, giving them a competitive advantage.

What is Earth’s crust like that is located the furthest away from the center of a mid-ocean ridge? Select all that apply.
less dense
older
newer
thicker
Answer:
The Earth's crust that is located furthest away from the center of a mid-ocean ridge is:
Older: The farther away from the center of the mid-ocean ridge, the older the crust becomes. This is because new crust is continually formed at the ridge center and moves away in opposite directions.
Thicker: As the crust moves away from the ridge center, it cools and contracts, becoming thicker.
Less dense: The older, thicker crust is also less dense than the newly formed crust at the ridge center.
Therefore, the correct options are: older, thicker, and less dense.

Consider a palm tree plantation in the Amazon, where only one species of tree is cultivated. What changes would this kind of low biodiversity bring to an ecosystem? Check all that apply. A. increased competition for fewer food sources B. organisms that are less suited to changes in the environment C. easier reproduction for organisms D. a higher economic value
The changes that this kind of low biodiversity would bring to an ecosystem would include increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.
What is biodiversity?Increased competition for fewer food sources, such as with only one species of tree, means that the organisms that depend on it for food and habitat would have to compete for limited resources. This can lead to a reduction in the overall population and diversity of the organisms in the ecosystem. Low-biodiversity ecosystems are less resilient to environmental changes, such as climate change or natural disasters. With only one species of tree, the organisms in the ecosystem would be less adaptable to changes in the environment and more vulnerable to extinction.
Hence, the changes that this kind of low biodiversity would bring to an ecosystem would be increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.

Shanice said the three types of mountains are folded, tilted, and volcanic. How should Shanice’s statement be corrected?

lifted should replace tilted
fault-block should replace tilted
Answer:
D. fault-block should replace tilted
Explanation:
The 3 types of mountains are: fold(ed), fault-block, and volcanic.
She listed tilted, which is not a main type. She did not list fault-block, so it should replace tilted.

Answer:
salt crystallization is a type of mechanical weathering.
Explanation:
Answer:
Honeycomb weathering
Salt can lead to a type of weathering called honeycomb weathering. Groundwater seeps into rock cracks by capillary action and eventually evaporates. This yields salt crystals, which increase the pressure in rocks. Eventually the rocks will break down. This can leave pits of salt crystals that resemble honeycombs.

E Astronomers measure distances to objects which are outside our solar system in light-years.Astronomers measure distances to objects which are outside our solar system in light-years.
F An astronomical unit is about 93 million kilometers.
A. The average distance between the Earth and the Sun, or A.U., is used to measure distances within our solar system.
D. Distances to things outside of our solar system are measured in terms of light-years (ly), which are the maximum distances light can travel in a year in a vacuum.
To calculate the immense distances in the cosmos, astronomers mostly employ two methods. An astronomical unit (A.U.), often known as the average distance between the Earth and the Sun, is used as a standard measurement within our solar system. One A.U. is equivalent to 150 million kilometres or 93 million miles. Within our solar system, it is used to calculate the separations between planets, asteroids, and comets. Second, astronomers use light-years to gauge distances outside of our solar system (ly). The distance that light can cover in one year in a vacuum, or 5.88 trillion miles or 9.46 trillion kilometres, is known as a light-year. We may use this method to calculate the huge separations between stars, galaxies, and other astronomical objects. As a result, astronomers employ A.U.
