PRODUCT DESCRIPTION

A poster highlighting the weathering and erosion process.

Weathering and erosion work together to change the environment.

Weathering is the process where surface rocks are broken down, worn away or dissolved into smaller and smaller pieces through mechanical or chemical processes.

Erosion is the process of moving these small, weathered rock particles to another location by the forces of wind, water, glaciers, waves or gravity.

Wind - Dust particles picked up and carried in the air by wind is an example of erosion.

Glaciers - Rocks and sediment moved by a glacier is an example of erosion.

Mechanical Weathering – The physical breakdown of rocks into smaller particles without changing its chemical composition.

Example: Tree roots growing and breaking through rock.

Chemical Weathering – The breakdown of rocks into smaller particles by changing its chemical composition. Water is perhaps the most powerful agent of chemical weathering.

Gravity - Rock particles falling from the cliff is an example of erosion.

Water & Waves - Rocks and sediment moving with the swell of waves and the current of water is an example of erosion.
