Mass Wasting & Glaciers

Front

What is mass wasting?

Back

Mass wasting is the movement of soil and rock down a slope due to gravity.

Front

What are glaciers?

Back

Glaciers are large masses of ice that form from compacted snow and move slowly over land.

Front

How do glaciers affect freshwater supply?

Back

Glaciers contain about 2/3 of the world's freshwater.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface and transported elsewhere.

Front

What is deposition?

Back

Deposition is the process where materials are dropped or settled after being transported by wind, water, or ice.

Front

What causes mass wasting?

Back

Mass wasting is primarily caused by gravity, but can be influenced by factors like water saturation and vegetation.

Front

Why is vegetation important in preventing erosion?

Back

Vegetation helps to anchor soil in place, reducing the risk of erosion and mass wasting.

Front

What happens to glaciers as they melt?

Back

As glaciers melt, they contribute to rising sea levels and can lead to increased erosion and deposition.

Front

What is a landslide?

Back

A landslide is a sudden and fast movement of rock and soil down a slope, often triggered by heavy rain or earthquakes.

Front

How do glaciers erode land?

Back

Glaciers erode land by sliding over it, scraping away soil and rock, and transporting debris.
