Deslizamiento de Terra

The video tutorial explains landslides, which are movements of earth, stones, and rocks on slopes. It covers the causes, including erosion, heavy rain, melting snow, and the role of plant roots. The impact of rivers, glaciers, and sea waves is also discussed. Earthquakes and volcanoes can trigger landslides by altering slopes. Landslides vary in size and can be destructive, as seen in the 1980 Mount Saint Helens event, which caused significant damage and created new lakes.

What is a landslide primarily characterized by?

• The movement of animals on a slope

• The movement of air currents on a slope

• The movement of stones, earth, and rocks on a slope

• The movement of water on a slope

Which natural factor is NOT mentioned as a cause of landslides?

• Plant roots

• Heavy rain

• Strong winds

• Melting snow

How can plant roots contribute to landslides?

• By absorbing all the water in the soil

• By preventing erosion

• By acting as a wedge and widening cracks in the soil and rock

• By strengthening the soil structure

What was the significant outcome of the Mount Saint Helens landslide?

• It stopped a river

• It caused a drought

• It formed several new lakes

• It created a new mountain

What is the potential impact of large landslides?

• They are always beneficial for the environment

• They can be extremely dangerous and destructive

• They only affect small areas

• They have no impact on human structures
