100

The type of weathering that breaks rocks into smaller pieces

What is Mechanical?

100

Name the three types of soil.

What are sand, silt, and clay?


100

This mechanical weathering takes place when water in a crack of a rock freezes.

What is ice wedging?

100

This is what is being tested by the scientist. 

What is the independent variable?
100

Weathering breaks down rocks and soil. Erosion ________________ rocks and soil. 

What is transport?

200

The type of weathering that keeps the chemical makeup of rocks the same

What is Mechanical?

200

This type of soil has a large surface space and holds water.

What is clay?

200

This is a constant rubbing of rocks due to gravity or water.

What is abrasion?

200

These cannot change throughout the experiment.

What are constants?


200

The two main agents of soil erosion are ______________ and _______________.

What are wind and water?

300

The type of weathering water is involved in

What is mechanical and chemical weathering?

300

Soils that allow water to flow through are called _______________. 

What is permeable?

300

These two living things break apart rocks.

What are plants and animals?

300

Every experiment must have this for comparison. 

What is the control?

300

Soil erosion takes place where the soil has been _________________. 

What is disturbed?

400

The process when oxygen strongly reacts to Earth's elements

What is oxidation?

400

This soil is made of organic material and makes fertile topsoil.

What is humus?

400

This changes the composition of a mineral by breaking it down.

What is chemical weathering?

400

This changes as a result of the independent variable.

What is the dependent variable?

400

This protects the soil where logging takes place.

What is replant forests?

500

This weak acid created by carbon dioxide and rainwater dissolves rocks

What is carbonic acid?

500

This is a combination of sand, silt, and clay.

What is loam?

500

Water chemically weathers rock in ____________.

What is hydrolysis?

500

This must be recorded and analyzed during and after every experiment.

Data

500

This protects agricultural farmland from erosion.
