Unit 2: Weathering, Erosion, Deposition, and Landforms

What are the two ways that rocks are broken down into smaller pieces?

• chemical weathering and physical weathering

• physical weathering and precipitation

• chemical weathering and dissolving

• abrasion and erosion

What is the difference between chemical and physical weathering?

• they both the same

• physcial changes the composition of rocks and chemical does not

• chemical changes the composition of rocks and physical breaks them down into smaller pieces

• physical changes the composition of rocks and chemical breaks them down into smaller pieces

• physical breaks down rocks and chemical does too

Wind picks up sediment from the ground and carries it aloft. As the wind slows, it deposits the sediment in other places, sometimes forming dunes. Which type of sediment will be dropped and deposited first as the wind slows?

• the biggest

• the lightest

• the smallest

• the heaviest

What are some ways that animals contriute to physical weathering? Must choose all correct answers.

• animals borrow causing abrasion

• animal movememnt exposes rocks to wind and water

• animals release acids that change the chemical composition of rocks

• animal casue acid precipitation

What living organisms contribute to physical weathering?

• Plants

• animals

• plants and animals

• neither

Which is the steepest side of a dune?

• the slip face

• the side facing the ocean

• the side facing away from the ocean

• the windward face

The roof of a cave eroded and became thinner over time. The roof then collapsed and the landform shown in the figure was formed.

• canyon

• delta

• cavern

• sinkhole

• glacier
