Weathering and Mass movements Review

Frost Wedging is a form of physical weathering caused by

• Expansion of water in the cracks of rocks

• The transformation of granite into a new substance

• Fast moving fluid substances down a hill

• The removal of the the outer layer of rock

The two main factors that affect the rate of weathering are

• Climate and location

• Location and moisture

• Climate and rock features

• Moisture and rock features

Chemical weathering is the most effective in what type of environment?

• A moist environment with low temperatures

• A moist environment with high temperatures

• A dry environment with low temperatures

• A dry environment with high temperatures

Which of the following is NOT a major component of soil?

• Mineral remains

• Humus

• Air

• Natural gas

Land with a steep slope is likely to have what type of soil?

• Poor quality

• High quality

• Mineral rich

• Moist

Which of the following is a type of mass movement. SELECT ALL THAT APPLY

• Mudflow

• Creep

• Waterfall

• Landslide

Which of the following events are commonly associated with mass movements? SELECT ALL THAT APPLY

• Heavy rainfall

• Tornadoes

• Earthquakes

• Droughts

Internal slope failure is commonly caused by what?

• Water and weak material

• Water and dry heat

• Weak material and plant growth

• Dry heat and plant growth

A creep is

• a slow, gradual movement of earth

• a quick movement of earth that behaves like a fluid

• a quick movement of rocks

• a slow, gradual movement of water

Mechanical Weathering happens when

• a substance is broken down but not changed

• a substance is transformed into a new substance

• a substance is covered by water

• a substance is transformed by natural means
