What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass. It occurs when the energy of the transporting medium (like water or wind) decreases, causing the materials to settle.

Front

What are the main types of weathering?

Back

The main types of weathering are physical weathering (breaking rocks into smaller pieces without changing their composition), chemical weathering (changing the chemical composition of rocks), and biological weathering (breakdown caused by living organisms).

Front

What causes soil formation?

Back

Soil is formed by the weathering of rocks and the accumulation of organic matter, minerals, gases, liquids, and organisms.

Front

What is a mountain?

Back

A mountain is a large landform that rises prominently above its surroundings, typically characterized by steep slopes and significant elevation.

Front

What is a plain?

Back

A plain is a flat or gently rolling area of land that is usually at a low elevation and often found near rivers or lakes.
