Erosion- a process in which the materials of Earth's surface are loosened, dissolved, or worn away and transported from one place to another by a natural agent, such as wind, water, ice, or gravity
Deposition- The process in which material is laid down
Types of Chemical Weathering
Chemical Weathering- The process by which rocks are broken down by chemical reactions.
Water- broken down by water
Wind- When wind blows sand and silt against exposed rock, the sand eventually wears away the rock’s surface.
Air- The oxygen in the air is reacting
Acids- These acids react with rocks in the ground
Examples and Pictures of Chemical Weathering
Types of Mechanical/Physical Weathering
Ice-Gouging. Ice digs into the ground and scratches it. Plucking-Ice picks up rocks off of the ground and takes it.
Living Things-Plants(root pry). Roots break the rock. Animals. Digging in the ground
Water-Movement(abrasion). Water weathers the surface of the rock.
Air-(wind). Air moves and breaks something off of a rock.

Types of Erosion
Erosion By Water
Water moved the sand
Erosion By Wind
The wind knocked pieces off of this rock
Erosion By living things
These cows can move rocks and soil
