Weathering

Destructive Forces

• The process in which a rock is broken down.
• Ice wedging
• Erosion
• Rust

Constructive forces

• Constructive forces are things that help build up the earth.
• volcanoes
• Tectonic plates
• Deposition

Chemical weathering

• The erosion or disintegration of rocks, building materials, caused by chemical reactions.
• Acid rain
• Rust
• Carbon Dioxide

Mechanical weathering

• The process of breaking down rocks by physical means.
• Ice Wedging
• Pressure
• Animals

Deposition

• The process of eroding or being eroded by wind, water, or other natural agents.
• Water
• Wind
• Abrasion

Deposition

• the process in which rocks, soil, and sediments are added to a landform.
• Glaciers
• water
• volcanic eruption

As you all know weathering and erosion are two different things. Weathering is the process of wearing away sediments from a land form. Erosion is the process of eroding or being eroded by wind, water, or other natural agents. The reason why erosion is not the same as weathering is because weathering is wearing sediments away. Erosion would be like water carving into a land form to make a divot in the land.
