Question

How is physical weathering different from chemical weathering?(1 point) Responses A. In physical weathering, the composition of the weather substance is changed. A. In physical weathering, the composition of the weather substance is changed. B. Physical weathering is always faster than chemical weathering. B. Physical weathering is always faster than chemical weathering. C. In chemical weathering, the composition of the weathered substance is changed. C. In chemical weathering, the composition of the weathered substance is changed. D. Chemical weathering is always faster than physical weathering.

Answer 1

The correct response is:

C. In chemical weathering, the composition of the weathered substance is changed.

Physical weathering breaks down rocks and minerals into smaller pieces without changing their chemical composition, while chemical weathering involves a change in the chemical composition of the minerals as they react with substances like water, oxygen, or acids.

Answer 2

Which of the following is the best example of physical weathering?(1 point) Responses A. acid rain breaking down rock A. acid rain breaking down rock B. plant roots splitting rock B. plant roots splitting rock C. students tearing paper C. students tearing paper D. iron in igneous rock rusting

Answer 3

The best example of physical weathering is:

B. plant roots splitting rock.

This process, known as root wedging, occurs when plant roots grow into cracks in rocks, causing them to break apart without changing their chemical composition.

Answer 4

There are many natural processes that shape the Earth's surface. These processes can act as constructive forces, destructive forces, or both. Which of the following best illustrates a natural process acting as a constructive force? (1 point) Responses A. Wind depositing sand to build up sand dunes. A. Wind depositing sand to build up sand dunes. B. A glacier weathering a mountainside. B. A glacier weathering a mountainside. C. A river eroding soil during a flood. C. A river eroding soil during a flood. D. Acid rain breaking down the surface of a rock.

Answer 5

The response that best illustrates a natural process acting as a constructive force is:

A. Wind depositing sand to build up sand dunes.

This process adds material to the landscape, effectively building up the Earth's surface, which is characteristic of constructive forces.

Answer 6

Which of the following is an example of the wind slowly causing changes in Earth's landforms?(1 point) Responses A. Dangerous crosswinds force a car off the road A. Dangerous crosswinds force a car off the road B. A hurricane blows the roof off a house. B. A hurricane blows the roof off a house. C. Hot gas blasts out of a volcano. C. Hot gas blasts out of a volcano. D. The wind wears down and smoothes rocky hills over time.

Answer 7

The example of the wind slowly causing changes in Earth's landforms is:

D. The wind wears down and smoothes rocky hills over time.

This process demonstrates how wind erosion gradually shapes and alters landforms over an extended period.

Answer 8

Global climate and weather patterns are driven by differences in the amount of heat energy in different areas of the Earth. Which statement best explains why different areas of the Earth have different amounts of heat energy?(1 point) Responses A. The solar radiation from the Sun is equally distributed across the Earth at all times. A. The solar radiation from the Sun is equally distributed across the Earth at all times. B. The Earth spins at different rates so the rotational energy of the Earth varies. B. The Earth spins at different rates so the rotational energy of the Earth varies. C. The gravitational energy from the Sun varies greatly in different regions of the Earth. C. The gravitational energy from the Sun varies greatly in different regions of the Earth. D. The Earth receives different amounts of solar energy in different regions.

Answer 9

The statement that best explains why different areas of the Earth have different amounts of heat energy is:

D. The Earth receives different amounts of solar energy in different regions.

This variation is primarily due to factors such as the curvature of the Earth, its axial tilt, and the angle at which sunlight hits different surfaces, leading to unequal heating of the Earth's surface.

Answer 10

Each day, changes take place in the atmosphere. All these frequent changes are called _______.(1 point) Responses A. rain A. rain B. climate B. climate C. wind C. wind D. weather

Answer 11

The correct response is:

D. weather.

Weather refers to the short-term atmospheric conditions, including changes in temperature, precipitation, and other factors that occur on a daily basis.
