Unit 6: Weathering, Erosion, Deposition

The process that breaks rocks apart without changing their chemical composition

• Chemical weathering

• Physical weathering

• Deposition

• Erosion

The process that moves bits of rock or soil from one place to another

• Chemical weathering

• Physical weathering

• Deposition

• Erosion

Changes within the rock's minerals that break down bonds and change the chemical makeup

• Chemical weathering

• physical weathering

• deposition

• erosion

The natural process in which eroded sediments, soil, and rocks are laid down and are added to a landform

• chemical weathering

• physical weathering

• deposition

• erosion

Chemical weathering is NOT caused by

• abrasion

• carbonation

• hydrolysis

• oxidation

Small, broken down pieces of rock are called

• sedimentary rock

• sediment

• smaller rocks

• crumbs

The movement of weathered rocks due to wind, rain, or gravity

• Chemical weathering

• Physical weathering

• Deposition

• Erosion

Flood water pounding against a canyon wall and wearing it down

• Weathering
• Erosion
• Deposition

Glaciers dropping rock and sand to form moraines (deposition of debris)

• Weathering
• Erosion
• Deposition

Over millions of years, the shape of mountains on Earth's surface can change to low hills and then rolling plains. These changes are most likely caused by-

• Folding and faulting

• Volcanoes and Earthquakes

• Human activity

• Weathering and Erosion
