Rocks, Erosion, Weather Review

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary
• Metamorphic, Igneous, Cementation
• Brown, Red, Gray
• Streak, Hardness, Breakage

This rock formed when bits of other rocks became pressed into a solid. What type of rock is it?

• Sedimentary Rock
• Metamorphic Rock
• Igneous Rock

This rock was formed when molten rock cooled into a solid. What type of rock is it?

• Igneous Rock
• Metamorphic Rock
• Sedimentary Rock

The process when rocks break into smaller pieces due to exposure to natural elements is called

• erosion
• weathering
• sediments

True or False: Once a rock is sedimentary, it cannot become an igneous rock.

• True
• False

What is process in which water, wind, and heat break down rock?

• weathering
• exfoliation
• cementation
• composition

When particles are eroded and moved, they are eventually laid down in a process called: 

• deposition
• weathering
• supposition
• refraction

When temperatures repeatedly go from hot to cold this can cause what type of geological process?

• weathering

• erosion

• deposition

• all of the above

What is erosion?

• When sediment is transported from one place to another

• When eroded materials are dropped or laid down.

• when sediment or rocks are broken down

• when rocks react with oxygen and water

What are glaciers?

• They are winding rivers that carry sediment to a delta

• They are waves that constantly crash against the shoreline.

• are huge masses of ice that move slowly over land.

• They are sand dunes that form from wind depositing sediments.
