Exam 10: Weathering and Mass Wasting

Oxidation is a type of physical weathering.

Dissolution is a good example of mechanical weathering.

Which of the following activities can induce mass wasting?

_______ involve the rapid sliding of large masses of bedrock on a steep mountain slope or from a high cliff.

The most dangerous and spectacular type of downslope movement is called a landslide.

The maximum slope angle that allows rock, sand, clay, and debris to stay in place without movement is called:

Plants can be responsible for mechanical weathering.

Explain the primary difference between mechanical weathering and chemical weathering?

Joint planes form as a result of an increase in pressure.

The process where minerals react chemically with water is called _______.

What is required to induce mass movements along the Palos Verdes Hill of Los Angeles, California and other similar developments in steep hillside settings?

Weathered rock moves down the slope into a collection of degraded debris at the base is called:

__________ is the process where oxygen and water react with metallic elements in minerals, making the minerals unstable and causing the rock to degrade in strength and eventually crumble into smaller particles.

The general term for excavations and other land disturbances produced to extract mineral resources is:

All the processes that physically disintegrate or chemically decompose a rock at or near the Earth's surface is called?

Chemical weathering is most effective in environments with:

_______ is the process of ice splitting rocks during freeze/thaw cycles.

Sandstone pillars such as the ones in the figure below are features that can be found in the southwestern US, but are unusual in the southeastern US. Which of the following explanations best account for this?

In general, landscapes of steeper relief experience __________ rate(s)of landform change compared with those of lower relief.

In the figure below, what type of weathering is being shown?
