Tsunamis are huge ocean waves that usually occur after an earthquake.
Tsunamis can cause massive flooding and destruction.
Hurricanes can result in the erosion of beaches.
Look at the beach before and after the hurricane.
Earthquakes are usually caused when rock underground suddenly breaks
along a fault. Earthquakes result in a sudden release of energy which causes the ground to
shake.
Volcanic eruptions occur only in certain places, usually along the edge of plates.
Volcanic eruptions result in the formation of new land including some islands in the ocean.
The new land is very fertile and rich in nutrients.
