Unit 7: Soil Layers & Formation

Which statement best describes the processes of weathering and erosion?

• Weathering and erosion are responsible for breaking down rock into particles & carrying away the sediment

• Weathering and erosion are responsible for depositing loose sediments at the bottom of the ocean

• Weathering and erosion are responsible for the amount of water in a river that transports sediments out to sea

• Weathering and erosion are responsible for the deposition, compaction, and cementation of sediments on the seafloor

Which of the following is mostly responsible for preventing erosion?

• weathering

• tilling land

• the presence of plants

• removal of trees

Select all that apply: which scenarios show physical/mechanical weathering?

• Oxidation occurs on a bicycle left out in the rain

• Ice wedges into cracks of rocks & prys them apart because of freezing & thawing

• Tree roots grow into cracks in rocks and pry them apart

• Air pollution combines with water droplets in the air, creating acid rain.

• Animals digging & burrowing in the ground
