What is the process of moving sediments from location to another?

• Deposition

• Erosion

• Weathering

• Compaction

The process of breaking up Earth's surface into sediment is called...

• sediment
• erosion
• weathering
• deposition 

What is sediment?

• the process of rocks being broken down and carried away
• bits of rock, sand, and silt caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material 

Which of these is an example of erosion

• Light Shinning onto a mountain
• Rain breaking down rock 
• Wind blowing away sediment
• All of the above

What happens when weathering and erosion work together?

• New Mountains are created
• The climate changes overnight
• Metal objects become rusty
• They change the Earth's surface

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

Which type of climate will have faster chemical weathering?

• Hot and Wet
• Cold and Dry
• Hot and Cold
• Cold and Wet

The process that breaks down rocks and other materials on Earth's surface is called

• weathering
• erosion
• soil conservation
• decomposition

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides

What is the major cause of weathering and erosion to form canyons?

• wind
• ice
• glaciers
• moving water
