Weathering and Erosion Review

What is weathering?

• A process that breaks down rocks into smaller pieces

• A shift in weather patterns

• The process by which mountains are formed

• The process by which the seasons change

How might a weathered mountain appear different from an unweathered mountain?

• The weathered mountain would be taller

• The weathered mountain would appear rounder in shape

• The weathered mountain would appear more jagged

• The weathered mountain would contain fewer trees

What impact does weathering have on soil formation?

• Chemical weathering adds helpful chemicals to the soil

• Rocks are broken down into smaller pieces, and finally into sediment

• Mechanical weathering adds ice to the soil, which turns into water

• Volcanic eruptions contribute metamorphic rocks to the soil

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

• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

When flowing water erodes land, it carries the particles downstream. Which statement describes what happens to these particles as the flow of water slows down?

• Larger particles float on the surface, and smaller particles sink.

  
  

• Particles continue traveling at the same speed and do not slow down.

  
  

• Particle movement also slows down and eventually float on the surface.

  
  

• Larger particles are deposited first, and smaller particles settle last.

  
  

Which choice is the BEST example of erosion?

• sand being deposited on a beach

  
  

• wind blowing trees over in a storm

  
  

• rainwater washing dirt down a hill

  
  

• tree roots growing in between rocks

Which of these is evidence of wind affecting rocks and/or soil over time?

• an avalanche occurring after heavy snow fall

  
  

• new plants growing in a flowerbed every spring

  
  

• patterns of ripples formed in sand on a playground

  
  

• the weather patterns of an area changing over time

  
  

Both wind and water can make changes to rocks and soil over time. Which image BEST shows the results of wind moving soil or rocks over time?
