How does wind cause weathering?

• Wind can not cause the weathering of rocks

• Wind can blow sand to make mountains

• Wind picks up sand or dry soil and carries it from one place to another

• Blowing wind can wear away a rock's surface and break it into smaller pieces

The image below shows lava flowing from the Krafla volcano in Iceland. How is a new land feature formed from lava?

• by the constructive process of lava hardening to add new land on top of the ground

• by the constructive process of lava depositing sediment to build up the surface of the ground

• by the destructive process of lava flow carrying sediment away from the volcano by erosion

• by the destructive process of lava weathering rock to carve a new landform in the volcano

What action would most likely be taken to control the damage that could occur?

• People would not be allowed to live in the area or enter the area

• Buildings in the area would be designed to withstand the earthquakes.

• Action would be taken to prevent the earthquakes from occurring.

• Action would be taken to prevent the earthquakes from occurring.
