Slow and Fast Changes to Land

Which of the following is a slow change to the Earth's surface?

• Rocks falling down the side of a hill
• An earthquake creating cracks on the road
• A glacier scraping down the side of a mountain
• Hot lava creating new land from a volcano

This landform was created by-

• glacier
• wind
• landslide
• water

Which of the following does NOT cause a slow change on the Earth's surface?

• earthquake
• ice
• water
• wind

A student was observing rocks he found at a river bed.  The rocks he found were smooth and rounded because they-

• formed from lava during an earthquake
• were part of a glacier that melted
• were in a river that had fast moving water
• rolled down a side of the mountain

When ocean waves crash against rocks, 

• the rocks will melt
• the rocks will explode as the waves hit them
• pieces of the rock may break off due to weathering
• the rocks will move to another quieter location

Water is flowing underground for millions of years. Eventually it carries away minerals, leaving a large empty space. What does that process create?

• Caves 
• Volcanoes
• Oceans
• Rivers

Heavy rains fall on a farm for several months. What might the farmer notice as a result? 

• An increase in soil due to deposition
• A decrease in soil due to erosion
• an increase in temperatures due to weathering

What might cause a sand dune to move from place to place?

• rushing rivers
• blowing winds
• freezing water
• weathering rock

A canyon might be formed by

• wind blowing
• ice freezing
• water moving
• snow falling

Which of the following is NOT caused by moving water?

• deep cracks forming
• smoothing of rocks
• dunes moving
• canyons forming
