Question

The smallest body of water is the stream(溪流）,a natural body of water that is found above ground and is often called a creek（河灣）as well. A river is a larger body of water that moves above ground, in a particular direction, and usually has a large amount of water in it. Rivers often go into other bodies of water. For example, The Chanjiang River goes into the sea. A lake is a large body of water that is completely surrounded（環(huán)繞)by land. A pond（池塘）is the same thing, only with less water and a smaller size. No one can tell you how big a pond can become before it is called a lake. A sea is a large body of water that is surrounded by land and connected to another body of water. The Caspian Sea（里海）is one that is surrounded by land. The Mediterranean Sea（地中海）is one that connected to another body of water, the Atlantic Ocean（大西洋）Why are these bodies of water called seas but not oceans? Geographers（地理學家）don't have a really good reason. An ocean, which is the largest body of water on the Earth, is generally thought to have no borders（邊界）
