Earth has different parts that work together to keep Earth in balance. The geosphere is the rocky part of Earth. The atmosphere contains all the air. The biosphere is made of all the living things. The hydrosphere consists of all the liquid water, snow, and ice. The magnetosphere includes the magnetic field surrounding Earth. All of these parts are needed for life to exist. Rain and snow in the hydrosphere give water to plants and animals. Plants take carbon dioxide from the atmosphere and change it into oxygen. Animals breathe in oxygen and breathe out carbon dioxide. The magnetosphere lets just enough of the Sun's energy through to keep plants and animals alive. When all these parts of Earth are in balance, plants and animals can stay alive and healthy. But it is possible for Earth to become unbalanced. If there is too much carbon dioxide in the air and not enough plants to change it to oxygen, weather patterns can change. Too much carbon dioxide also makes oceans become less healthy for fish. If too much ice melts, sea levels can rise, leaving less land for plants and animals to live on. We can help keep Earth in balance by cleaning the air and the water. We can choose to use products that are Earth friendly, use fewer plastics, and recycle. Everyone can help!
