Slow changes to earth check

The diagram shows a barrier island before and after a hurricane. What can you infer from the diagram?

• Barrier islands are constantly changing but never being built up or destroyed.

• Strong storms can take sand away.

• The saltwater evaporates the sand causing the island to get smaller.

• Barrier islands are formed by strong winds.

Erosion and weathering can both cause changes to the surface of the earth. Which of the following happens only because of erosion, and not because of weathering?

• Plant roots break rocks underground.

• Rocks become smooth and round.

• Ice breaks rock as it freezes in cracks.

• Rocks are moved from one place to another.

Explain how the stalagmites in a cave are formed.

• Wind deposits dust and rocks into caves which build up over time.

• Water drips slowly to the cave floor and deposits minerals as it evaporates.

• Moving water erodes shapes as it washes through the cave.

• Ice forms overnight and cracks the rocks into shapes before it melts away.
