Wind, Waves, & Glaciers

What is wind erosion?

Back

Wind erosion is the process by which soil and rock are removed from the Earth's surface by the wind. It often occurs in dry, arid regions where vegetation is sparse.

Front

Where is wind erosion most commonly found?

Back

Wind erosion is most commonly found in deserts, such as the Atacama Desert, where loose sediments can be easily picked up and transported by strong winds.

What type of sediments are typically deposited by wind?

Back

Sediments deposited by wind are generally pitted, meaning they have small holes or indentations due to the abrasive action of wind-blown particles.

Front

How does a glacier erode a valley?

Back

A glacier erodes a valley by moving slowly over the land, carving out a U-shaped valley as it transports and deposits sediments.

What shape is a valley eroded by a glacier?

Back

A valley eroded by a glacier is generally U-shaped, characterized by steep sides and a flat bottom.

How can you determine wind direction by observing a sand dune?

Back

You can determine wind direction by observing that the wind blows up the gentle slope of the dune and down the steeper slope.

Front

What is deposition in the context of wind and water?

Back

Deposition is the process by which sediments are laid down or settled out of a transporting medium, such as wind or water.

On which side of a groin will sand deposition occur?

Back

Sand deposition will occur on the east side of a groin, where the current slows down and allows sediments to settle.

Front

What is the role of glaciers in shaping landscapes?

Back

Glaciers shape landscapes by eroding rock and soil, transporting sediments, and depositing them in new locations, creating features like valleys and moraines.

What are the main factors that influence wind erosion?

Back

The main factors influencing wind erosion include wind speed, vegetation cover, soil moisture, and the type of soil or sediment present.
