What causes the MOST erosion on Earth?

• running water
• wind
• chemical action
• glaciers

Which is an example of chemical weathering?

• rocks hitting each other in a swift river
• a strong wind blowing sand through a canyon
• ice forming in cracks in rocks
• acidic water dissolving limestone

Why are the rocks and pebbles found in riverbeds usually smooth?

• The rocks are very old.
• Animals in the river keep rubbing against the rocks.
• Rivers only flow where rocks are smooth.
• The rocks are worn smooth by rubbing against other rocks.

Which one of the following is MOST LIKELY to make a rock break open?

• dew evaporating on the rock
• tree leaves decaying on the rock
• snow melting in a crack
• water freezing in a crack in the rock

This picture shows a sea arch.  As erosion from ocean waves continues, what will most likely happen to the hole in this landform?

• It will become larger.
• It will fill with sediment.
• It will remain the same size.
• It will be covered with water.
