Earth

Earth is the third planet from the Sun in our solar system. It has a rocky surface covered mostly by water, which makes it the only known planet with abundant life. The planet's atmosphere, consisting mainly of nitrogen and oxygen, protects us from harmful space radiation and helps regulate climate. Earth's surface is dynamic, with processes like plate tectonics, weather, and erosion constantly shaping it. Its distance from the Sun allows for a temperature range suitable for diverse ecosystems. Earth provides the environment necessary for living organisms and is unique in its capacity to support complex life forms.
