Landslides flashcard

Front

What is the primary force responsible for landslides?

Back

Gravity is the primary force responsible for landslides.

Front

True or False: Increased rainfall and earthquakes contribute to landslides.

Back

True. Increased rainfall and earthquakes are significant contributing factors to landslides.

Front

True or False: A previous landslide in an area reduces the likelihood of future landslides.

Back

False. If a landslide has occurred in an area, it may be more likely to happen again.

Front

What type of landslide involves the rapid downward movement of material?

Back

A fall is a type of landslide that involves the rapid downward movement of material.

Front

Define a landslide.

Back

A landslide is the downward movement of soil, rock, or vegetation under the influence of gravity.

Front

What are the main types of landslides?

Back

The main types of landslides include falls, topples, spreads, and flows.

Front

What role does water play in landslides?

Back

Water can saturate soil, reduce friction, and increase the likelihood of landslides.

Front

What is a debris flow?

Back

A debris flow is a type of landslide that consists of a mixture of water, soil, and rock that moves rapidly down a slope.

Front

How can human activity contribute to landslides?

Back

Human activities such as deforestation, construction, and mining can destabilize slopes and increase the risk of landslides.

Front

What is the difference between a landslide and an avalanche?

Back

A landslide involves the movement of soil and rock, while an avalanche specifically refers to the rapid flow of snow down a slope.
