Unit 3 Lesson 1 Quiz Landforms

Wind, water, and ice are involved in both weathering and erosion. However, weathering and erosion are two different processes. Which sentence states a difference between weathering and erosion?

• Erosion moves rocks to a new location.
• Weathering moves rocks from place to place. 
• Erosion breaks down rocks but doesn’t move them. 
• Weathering moves rocks without breaking them down.

A glacier is a large mass of slow-moving ice that flows down a slope. Glaciers cause erosion on Earth. Which of the following landforms is formed by a glacier?

• delta
• sea arch
• moraine
• sand dune

Elements in nature such as rock and ice affect one another.  Which statement describes the process shown in the diagram?

• Ice changes into rock. 
• Ice seals the crack in the rock.
• Ice causes erosion to take place. 
• Ice forms in a crack and causes the rock to break.

Trace the path of the river in the picture. Which of the following processes cause the formation you see at the end of the river?

• Gravity caused rocks to fall from the mountain. 
• Wind caused sand to build up many sand dunes. 
• Melting ice caused large puddles to form a river delta. 
• Sediments of silt and sand were deposited to form a delta.

Which of these is an example of how a glacier causes erosion to happen?

• As glacial ice melts, lakes are formed. 
• Glaciers drop off sediments forming moraines. 
• Glaciers pick up rock and soil and move them along.
• Glaciers form when snow and ice pile up over years. 

Weathering is defined as the process by which rocks are broken down into smaller pieces. Which of the following choices is an example of weathering?

• glaciers creating moraines 
• wind blowing dust across flat land
• plant roots breaking apart rock
• ocean waves depositing sand on beaches

River deltas are triangular deposits of sediment that are created by the flow of water at the mouth of a river.  Which kinds of materials make up the sediment that forms a river delta such as the one in the picture?

• boulders and pebbles
• trees and branches
• ice and snow
• silt and sand
  

Some natural events cause landforms to change quickly. Other events cause change to happen slowly. Which of the following events causes landforms to change quickly?

• glacier 
• erosion
• landslide 
• weathering

Some kinds of weathering and erosion cause landforms to change quickly. Other kinds cause change to happen slowly. Which of the following statements is true?

• Deltas appear quickly. 
• Waves change landforms slowly.
• Landslides cause change slowly. 
  
• Glaciers change landforms quickly. 
  

Sadie builds a bridge of sticks and places it on top of two blocks of wood. She moves the blocks. The bridge collapses. What natural event does Sadie's model show?

• the shifting of rocks along a fault
• loose rocks sliding during a landslide 
• the movement of a glacier over land
  
• magma forcing its way to Earth's surface
