　　The earth did not always look the way it does today. Once the sea covered more of the land. Then mountains pushed up. They pushed up through the water. Land from the bottom of the sea became mountain tops. Seashells and fish bones were pushed up too. They were now far away from sea water. They were left high and dry.
