Earth Changes

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

• sediment
• erosion
• weathering
• deposition 

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

• Deposition

• Erosion

• Weathering

• Compaction

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 

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

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
• Plants don't weather rocks

Deltas are mainly created by the process of -

• deposition

• weathering

• waves

• erosion

Wind blowing sand from one location to another

• Weathering
• Erosion
• Deposition

Which of these are an example of erosion?

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

How would a fast-flowing river be most likely to move sand-sized particles of sediment?

• It would lift them and carry them downstream.
• It would dissolve them completely in solution.
• It would roll or slide them along the streambed.
• It would deposit them on the streambed.

Which of these is NOT an example of how wind can change the surface of the Earth?

• Lift and carry sand in a desert

• Creating a canyon by depositing sediment

• Weathering large rocks into arches and hoodoos

• Change the shape of sand dunes on a beach
