WEDS Everything

Choose TWO descriptions below that represent Erosion.

• Rain washing away dirt from a hillside

• Water getting in cracks of rocks, freezing, and breaking them

• Wind hitting the top of a mountain for thousands of years creating arches.

• Waves moving sand from one place to another

Sand and small pebbles are examples of

• deposition

• agents

• exfoliation

• sediments

What is the main agent that causes landslides, mudflows, slumps, and creeps to occur?

• water

• gravity

• ice

• wind

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

• Deposition

• Erosion

• Weathering

• Compaction

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

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

Which agents  break down earth materials?

• wind only
• earthquakes and gravity
• ice and 007
• wind, water, and ice

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

What is weathering?

• The movement of sediment

• The breaking of sediment

• The dropping of sediment

What is deposition?

• The movement of sediment

• The breaking of sediment

• The dropping of sediment
