Landforms, Weathering and Erosion

When hiking in the mountains, Tanya observed a narrow valley with water running through it. What most likely caused the valley to form?

• an earthquake

• weathering by water

• rock landslide

• erosion by wind

In what ways are rocks eroded and sand deposited?

• Rocks are eroded by wind as sand. Sand is deposited as abrasion.

• Rocked are eroded by abrasion. Sand is deposited by wind as dunes.

• Rocks are eroded by tiny particles moving downward. Sand is deposited by erosion as dunes

• Rocks are eroded by water and wind. Sand is deposited by more water and wind.

How does a delta form?

• a river slowing down
• it's just a river that empties into an ocean or lake
• the current of the river speeds up at the mouth causing sediment to wash away
• the current of the river slows down causing sediment to deposit

Which of these landforms was made by deposition?

• River mouth 
• Delta 
• Meander 
• Canyon 

Many processes that shape Earth happen over thousands of years. Some processes happen much more quickly. Which of the following has the potential to change Earth's landforms quickly?

• The carving of a valley by a glacier

• The formation of a canyon by a river

• The erosion of sand on a beach by storms

• The weathering of rocks by wind

Dalton noticed that recent rain had loosened up the dirt in his backyard. As a result, much of the dirt had moved around. There were holes and mounds where the dirt had been level before. This is an example of which of the following?

• An earthquake

• Weathering

• A mudslide

• Erosion

Ricky created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The other was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Ricky's model explain how glaciers change Earth's surface?

• The rocks and sand contained in most glaciers create grooves in Earth's surface.

• The rocks and sand contained in some glaciers fill the grooves in Earth's surface.

• Pure glaciers and glaciers that contain rocks and sand affect the Earth in exactly the same way.

• The water in pure glaciers cools Earth's surface.

How will placing rocks offshore affect the coastline?

• They will form an arch

• They will form a sea stack

• They will decrease the impact of the waves

• They will increase the impact of the waves
