What is the Kinetic Molecular Theory?

Back

A scientific theory that explains the behavior of gases in terms of particles in motion, based on many observations and investigations.

Front

What are the two main types of weathering that break down rocks?

Back

Chemical weathering and physical weathering.

Front

What is the rock cycle?

Back

A continuous process that describes how rocks change from one type to another over time.

Front

What must happen to igneous rock to become sedimentary rock?

Back

It must be broken down into sediment by weathering and erosion.

Front

Is the rock cycle a process that ends after a rock is formed?

Back

No, the rock cycle is a continuous process.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is abrasion in the context of rock breakdown?

Back

The process of scraping or wearing away of rocks due to friction.

Front

What is sediment?

Back

Small, solid pieces of material that come from rocks or living things.

Front

What is the difference between chemical weathering and physical weathering?

Back

Chemical weathering involves changes in the chemical composition of rocks, while physical weathering involves the physical breakdown of rocks without changing their chemical composition.

Front

What role does gravity play in erosion?

Back

Gravity helps to pull rocks and soil down slopes, contributing to erosion.
