X. Read the passage carefully, then do the tasks.
Elephants on the coast of Thailand are acting strange. They stamp their feet and motion
toward the hills. The sea draws back from the beaches. Fish flop in the mud. Suddenly, a huge
wave appears. This is no ordinary wave. It is a tsunami!
Tsunami waves are larger and faster than normal surface waves. A tsunami wave can
travel as fast as a jet plane and can be as tall as a ten-story building. For a tsunami to occur,
there must be some kind of force that causes the ocean water to become displaced. Most
tsunamis are caused by underwater earthquakes. However, volcanoes, landslides, large
icebergs, and even meteorites are capable of causing one of these mighty waves. Tsunamis are
extremely powerful. Because tsunami waves are so strong, they can kill people, damage
property, and completely ruin an ecosystem in just one hour.
