Weathering, Erosion & Deposition

How do plants most commonly break large rocks into smaller pieces?

• Seeds from plants fall onto rocks and release acidic compounds.

• Plant roots grow into cracks in rocks.

• Stems of plants surround and squeeze rocks.

• Plant protects surrounding rocks from extreme temperatures.

What is the process of transporting 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 

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

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 correct order of the processes?

• they all happen at the same time
• erosion, weathering, deposition
• weathering, erosion, deposition
• weathering, deposition, erosion
