How does the Sea cause Erosion?

• Wears away valleys at the bottom and the sides of it

• Coastlines are under constant attack by waves

• Wears away bits of rock from its bed and the bank on either side of the channel

• Bulldozers or Lorries move large amounts of soil or loose rock, remove trees and vegetation which allows water, wind and ice to erode the land more easily

• Picks up tiny particles of sand and blast them against anything
