Landforms/Weathering and Erosion

__________________ is the most significant form of erosion.

• Glaciers

• Waves

• Water

• Wind

What is the difference between weathering and erosion?

• Deposition breaks rocks down, weathering carries sediment away

• Weathering breaks rock down and erosion moves it

What are the agents of erosion?

• deflation and deposition

• water, wind, ice, gravity

• oxidation, acid rain, abrasion, root rust, root pry, abrasion

NGSS.MS-ESS2-4

(a)   is the breaking down of rocks that does not change the mineral makeup of the rocks- just makes smaller pieces.

• Mechanical weathering

• Chemical weathering

(a)   occurs when materials containing iron are exposed to oxygen and water.
