Weathering,Erosion and Mass Movement 3

 What is erosion?

• the process of moving water, moving ice, or wind carrying away a part of a rock
• the process of a part of a rock loosened usually by nature
• a natural event that happens quickly, such as lightning striking a tree

Type of landslides that involve rocks, are very to extremely rapid and can travel great distances.

• creeps
• mudslides
• rock fall
• slumps

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

• weathering
• erosion
• soil conservation
• decomposition

What type of Weathering is caused by animal actions?

• Chemical Weathering 
• Erosion 
• Mechanical Weathering 
• Animals 

The most important factors in determining the rate of weathering are - 

• carbon dioxide and acid rain
• abrasion and acids from plant roots
• animal actions and oxygen
• rock type and climate

What is mass movement?

• When rain causes the land to become very muddy and flow across the land
  
• When rivers carry pieces of dirt and sediment
  
• When gravity causes material to move uphill
  
• When gravity causes material to move downhill
