Presentation transcript:

What moved each of these sediments? How do you know? b) a) c) d)

Aim: How do weathered fragments get carried away? Topic: Unit 4 Main Idea: Erosion

How did this boulder end up in the middle of the woods?

The process where weathered fragments are carried away. 1) Define erosion: The process where weathered fragments are carried away.

2) Agents of Erosion Abrasion by sand Carries small particles Features Wind Abrasion by sand Carries small particles Pitted surface

outlier arch

Faster flow=more power Features Water Faster flow=more power #1 agent of erosion Rounded particles “V”-shaped valley Fastest in the middle Just below the surface

The Grand Canyon and the Colorado River

Animals

Striations (scratches Features Glaciers “U” shaped valley “rivers of ice” Striations (scratches in bedrock) Erratics (boulders in odd places)

talus Driving force of all agents Jagged edges Features Gravity Features Gravity Driving force of all agents Jagged edges Mass movement: avalanche, mudslide, landslide, creep (very slow) talus
