How Does Water Change Earth's Surface?

During a storm, rainwater can quickly erode soil by...

• soaking into the soil and making it damp
• getting absorbed by plant roots in the soil
• hitting and loosening the soil at the surface
• all of the above

Eroded materials deposited in new areas is called 

• crust
• mud
• rock
• sediment 

What is sedimentary rock?

• solid rock formed in layers from deposited sediment
• soft rock that weathers and becomes sediment
• sediment that has been washed away by water 
• sediment that forms under water 

What is the process of ice wedging? 

• blocks of ice freeze together and create a large block
• water in a pond freezes into a single piece of ice
• cracks in a rock get bigger when water inside freezes 
• snow and rocks are deposited in layers and form sedimentary rock

Landforms created by weathering, erosion, and deposition take how long to form?

• hours 
• days
• months 
• years 

Glaciers traveling down a mountain create a valley by carving what shape?

• s shape
• v shape
• u shape
• x shape

Where would you find the oldest layer of sediment in sedimentary rock?

• the top layer
• the bottom layer
• the middle layer
• all layers are the same age 

The Grand Canyon was formed after years of weathering and erosion caused by...

• rainwater
• The Atlantic Ocean
• The Mississippi River
• The Colorado River 

Which factors will affect the amount of weathering and erosion?

• slope
• amount of water 
• material 
• all of the above

Where is ice wedging most likely to occur?

• Antartica
• California 
• Florida 
• Australia
