The tallest sand dunes in North America are found in Great Sand Dunes National Park and Preserve in Colorado. These dunes were formed from the sand at the bottom of a dry lake bed. Which of the following agents is most likely responsible for the formation of the sand dunes?

Water

Wind

Gravity

Ice

2 / 15

Which of the following is an example of deposition?

Glaciers move slowly over sediment, chipping away at different formations.

Wind carries sand and places them into piles.

Water breaks down rock after years of flowing over it in a river bed.

Acidic rain washes over soil and changes the composition of it.

3 / 15

Which rock does acidic rain chemically weather to create holes?

basalt

granite

calcite

soil

4 / 15

In some climates, temperatures drop significantly at night.

How could this impact weathering of rocks?

This would increase the likelihood of acidic rainwater dissolving rocks like calcite.

This could cause plants to grow faster.

This could cause frost wedging as water in rocks repeatedly freezes at night and melts in the day.

This could cause more chemical weathering because chemical reactions occur more often at colder temperatures.

5 / 15

Why is acidic rain falling on calcite not an example of physical weathering?

It changes the composition of the rock.

It does not cause the rock to change.

It takes a much longer time to change the rock.

It changes the rock by creating cracks.

6 / 15

Which of the following are the three agents of erosion and deposition?

water

wind

ice

light

7 / 15

Which of the following does not lead to erosion?

water

wind

ice

heat

8 / 15

How is physical weathering different from chemical weathering?

Physical weathering breaks down the rock, and chemical weathering changes the rock's composition.

Physical weathering breaks down the rock, and chemical weathering makes rocks smaller while keeping their shape.

Physical weathering changes the makeup of a rock, and chemical weathering makes rocks change shape.

Physical weathering breaks down the rock, and chemical weathering only affects the rock's surface.

9 / 15

Which of the following are examples of physical weathering?

carbon dioxide dissolving in rainwater to make acidic water

calcite reacting in acidic rainwater

plant roots growing into the cracks of a rock

frost wedging

10 / 15

Which of the following is an example of chemical weathering?

iron in the rock reacting and forming rust-colored minerals

worms and insects making holes in a rock

plant roots growing into the cracks of a rock

freezing and melting of water in the cracks of a rock

11 / 15

The image above depicts the effects of chemical weathering breaking down limestone. Which type of chemical weathering causes this reaction?

Acid rain

Oxidation

Abrasion

Exfoliation

12 / 15

The breaking down of rocks and other materials on the Earth's surface.

Deposition

Exfoliation

Weathering

Erosion

13 / 15

Which three factors affect soil formation?

worms, air, and water

mineral material, organic matter, and air

rock type, biological activity, and climate

bacteria, weathered rock, and soil

14 / 15

The process by which rock and soil are moved from one place to another is called

Chemical weathering

Deposition

Mechanical weathering

Erosion

15 / 15

Worms play an important role in soil formation. They help to ........

nourish the soil with their waste

open ways for water and air to get into the soil

prevent the build-up of bacteria in the soil

soak up moisture in the soil for easier erosion
