Can wind change the surface of a volcano?
Question Date: 2018-12-02
Answer 1:

Yes! Wind, like water and ice, is a very powerful force for erosion.

Erosion one of the main processes that change how Earth's surface looks. It involves the breakup of rocks into small sediments, that can then be carried away. This is how sand is transported down the coast, how river channels form, and why we worry about the coastal cliffs collapsing and breaking away. Erosion helped create the Grand Canyon, as a river cut down through the bedrock. Erosion also transports sediments from the top of the Santa Ynez mountains down into the Santa Barbara Channel in the ocean. And erosion can change the surface of a volcano in the same way.

Some really old volcanoes have slowly been eroded away so that only the central magma chamber is exposed, or a side vent is exposed. This erosion could be caused by wind, water, or ice. Wind can also blow away ash that is erupted, redistributing the ash material to the bottom of the volcano or even further away.

Answer 2:

Yes, wind erodes any land surface, including those of volcanoes. So wind can change the surface of a volcano.

Answer 3:

Wind can most directly affect the surface of a volcano in two ways.

The first is that wind can erode the surface of a volcano by blowing small sediment particles over it and gradually sanding it away. Wind could also affect how a volcano is built up in the first place. If the eruption ejects ash, small rocks, or lava droplets into the air and the wind is blowing hard in one direction, more material will be deposited on the downwind side of the volcano.
