abrasion

• the process of glaciers   scraping along rock and   smoothing their surfaces

• rock foundation 

• the mixture of carbon   dioxide and water

• the transportation of   weathered rock pieces   called sediments

frost wedging

• a  type of weathering   that  occurs when water enters the cracks in rocks, freezes and melts   continuously

• the process of glaciers   freezing to bedrock and taking layers of sediment with them when they move 

• a specific type of water erosion that occurs when a single raindrop causes soil to “jump” and creates a small crater

• the process of weathering that occurs when rocks heat up, expand, cool off, and  contract  

ice thrusting

• a  type of weathering   that  occurs when water enters the cracks in rocks, freezes and melts   continuously

• the process of glaciers   freezing to bedrock and taking layers of sediment with them when they move 

• a specific type of water erosion that occurs when a single raindrop causes soil to “jump” and creates a small crater

• the process of weathering that occurs when rocks heat up, expand, cool off, and  contract
