Earth and water

Earth is the big rock we live on, and water is the wet stuff that comes out of the faucet and makes puddles outside. The Earth is mostly covered with water, but we can't drink all of it because some of it is salty and some of it is dirty. We need water to survive, but we also need the Earth for things like growing food and building houses. Sometimes the Earth moves and shakes, and when it does, it can cause big waves in the water. But we also need the water to keep the Earth from getting too dry and dusty. So the Earth and water need each other to keep everything in balance and to keep us healthy and happy.
