| Some things happen that we can not stop. We can not stop the power of the nature. For example, a flood comes when there is too much water on the land. Sometimes, it can come after a big storm when too much rain falls on the land. Sometimes, it can come after a big rainstorm out at sea where too much sea water comes onto the land. Fast moving flood water can hurt us. They can also hurt our homes. We cannot stop a flood from coming, but we can try to stop the water from coming into our homes. We can try to stop the water by making a wall with sandbags. Sometimes, the sandbags help stop the water. Sometimes, they don't. An earthquake happens where the land moves. The land goes up and down and all around. The land shakes. We can get hurt by things that fall down in an earthquake. Falling things can start fires. We can not stop an earthquake from coming. We can try to make our houses strong so that they will not fall down in an earthquake. | |||
