F(1) Lesson 1: Weathering, Erosion and Deposition

Front

Weathering

Back

The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

Erosion

Back

The process by which soil, sand, and rock are removed from one location and transported to another.

Front

Deposition

Back

The process by which sediments, soil, and rocks are added to a landform or landmass.

Front

Physical Weathering

Back

The mechanical breakdown of rocks and minerals without changing their chemical composition.

Front

Chemical Weathering

Back

The process of breaking down rocks through chemical reactions, often involving water and atmospheric gases.

Front

Acid Rain

Back

Rainfall made acidic by atmospheric pollution that causes environmental harm, typically to forests and lakes.

Front

Sediment

Back

Solid material that is moved and deposited in a new location by water, wind, ice, or gravity.

Front

Abrasion

Back

The process of scraping or wearing away rocks and sediments through friction.

Front

Wave Action

Back

The impact of waves on the shore, which can cause erosion and shape coastal landscapes.

Front

Oxidation

Back

A chemical reaction in which a material combines with oxygen to form an oxide, often leading to rusting in rocks.
