Topic 5: Earth’s Surface Systems Exam Review

Earthworms help farmers. Many farmers add them to their farmland because they help form rich soil to grow crops in.

As earthworms move through soil, they turn it over by exposing rocks and breaking up clumpy soil. Which process does this describe?

• Erosion

• Deposition

• Chemical weathering

• Physical weathering

Earthworms help farmers. Many farmers add them to their farmland because they help form rich soil to grow crops in.

Earthworms mix different layers of soil together by carrying humus from the surface down into the subsoil. Humus is a dark-colored substance made up of a variety of materials. Which two of the following are found in humus?

• Dead leaves

• Living Plants

• Limestone rock

• Decaying organisms

Sinkholes are extremely dangerous because they occur quickly and without warning. Sinkholes are a result of both mechanical and chemical weathering. Match the descriptions with the correct type of weathering that lead to the formation of sinkholes.

Pick two for chemical weathering:

• Limestone rock breaks into smaller pieces.

• Limestone rock is dissolved by water underground

• Pressure changes on the surface cause the ground to collapse

• When calcium carbonate rock sits in the water, it forms bubbles

• Landslides

• Glacial action

• Chemical weathering

Which change occurs as a result of wind slowing down?

• Erosion

• Deposition

• Chemical weathering

• Mechanical weathering

How are erosion and deposition alike?

• Both change Earth’s surface over time

• Both build up Earth’s surface quickly

• Both wear down Earth’s surface slowly

• Neither changes Earth’s surface
