Mass Movement, Wind, and Waves

Front

What is mass movement?

Back

Mass movement refers to the downward movement of soil and rock due to gravity, which can occur rapidly (like landslides) or slowly (like soil creep).

Front

Define deposition in the context of geology.

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring in new locations after being transported by wind, water, or ice.

Front

What is the primary cause of erosion on beaches?

Back

Waves are the primary cause of erosion on beaches, as they continuously impact the shoreline, wearing away rocks and sand.

Front

True or False: Erosion can occur when rain hits the dirt ground.

Back

True. Erosion can occur when raindrops dislodge soil particles, which can then be carried away by water.

Front

Which climate is associated with faster mechanical weathering?

Back

Cold and Dry climates are associated with faster mechanical weathering due to freeze-thaw cycles that break down rocks.

Front

What is a mudslide?

Back

A mudslide is a type of mass movement that involves the rapid flow of water-saturated soil and debris down a slope.

Front

Explain the term 'soil creep'.

Back

Soil creep is a slow, gradual movement of soil down a slope, often caused by the expansion and contraction of soil due to temperature changes.

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by lifting and transporting fine particles, especially in arid environments, leading to the formation of features like dunes.

Front

Define the term 'landslide'.

Back

A landslide is a sudden and fast movement of rock, earth, or debris down a slope, often triggered by factors like heavy rainfall or earthquakes.

Front

What is the difference between erosion and weathering?

Back

Erosion is the process of transporting soil and rock, while weathering is the breakdown of rocks into smaller pieces without movement.
