Science Module 2

The breaking down of rocks and other materials on the Earth's surface.

• Weathering

• Abrasion

• Erosion

• Deposition

Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.

• Chemical Weathering

• Physical Weathering

• Delta

• Floodplain

The process that breaks down rock through chemical changes

• Physical Weathering

• Sandbar

• Chemical Weathering

• Mountain

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another

• Delta

• Weathering

• Acid Precipitation

• Erosion

Process in which sediment is laid down in new locations.

• Erosion

• Abrasion

• Delta

• Deposition

a mass of material deposited in a triangular or fan shape at the mouth of a river or stream

• Delta

• Floodplain

• Coastline

• Dune

The land adjacent to a river

• Mountain

• Shoreline

• Floodplain

• Delta

a long ridge of sand or narrow island that lies parallel to the shore

• Lake

• Ocean

• Glacier

• Barrier Island

The break down and wearing away of rock material by the mechanical action of other rocks

• Abrasion

• Erosion

• Mechanical Weathering

• Physical Weathering

When fossil fuels are burned, other chemicals combine with water in atmosphere to produce stronger acids and then fall to earth

• Abrasion

• Delta

• Acid Precipitation

• Weathering
