Weathering is not caused by 

• rivers flowing from the mountains
• strong winds blowing
• the rotation of the earth

Volcanoes create new land on the Earth’s surface when –

• lava flows then cools and hardens to form rock.

• an eruption destroys the side of a mountain.

• magma forms giant underground chambers.

• saltwater touches lava and changes into steam.
