Weathering

3
Weathering - is the wearing down of rocks on the Earth’s surface by wind, water, and ice. o Weathering can be caused by water seeping into cracks in rocks, freezing, expanding, causing the cracks to get bigger, and over time breaking the rock apart. o Rain and running water also help to break down rocks into smaller particles. o Wind carrying sand and other particles can also wear down rocks over time.

Weathering- is the wearing down of rocks on the Earth’s surface by wind, water, and ice.

o Weathering can be caused by water seeping into cracks in rocks, freezing, expanding, causing the cracks to get bigger, and over time breaking the rock apart.

o Rain and running water also help to break down rocks into smaller particles.

o Wind carrying sand and other particles can also wear down rocks over time.

Erosion- is the process in which rock, soil, and sand are broken down and moved away.

Wind- can wear down rock and blow away sand and soil.

Water- Streams and rivers break up rocks and soil and carry them to a different location.

Ice- Glaciers cause erosion by scraping the ground along their paths and carrying away the sediments.

Page 3: Weathering

Deposition- is the processes by which rocks, soil, and other sediment are deposited in new places.

Dune- Hill of sand on beaches and in dry deserts formed by blowing sand.

Beach- Area of shoreline where waves have deposited sand and sediment from the ocean.

Deltas- Area formed when a river’s current slows down as at flows into an ocean, sea, or lake and drops the sediment it is carrying.

Flood Plain- Area built when a river, creek, or stream floods and leaves behind mud and sediment.

Glacial Moraine- Area formed by gravel, rocks, sand soil scraped, carried and left behind when a glacier retreats.
