The Earth is the third planet from the Sun and the only known planet to harbor life. It is a rocky planet with a solid surface and is composed of various layers, including the crust, mantle, and core.
The Earth is estimated to be around 4.54 billion years old. This age is determined through various scientific methods, including radiometric dating of rocks and fossils.
The Earth's atmosphere is primarily composed of nitrogen (78%) and oxygen (21%), with small amounts of other gases such as carbon dioxide, water vapor, and argon. It also contains layers of ozone that protect the planet from harmful UV radiation.
The Earth is the third planet from the Sun and is one of the four terrestrial planets in our solar system. It plays a crucial role in providing the right conditions for life to exist, such as a habitable temperature range and the presence of liquid water.
The Earth's rotation on its axis and its tilt on its axis (23.5 degrees) are responsible for the changing of seasons. As the Earth orbits around the Sun, different parts of the planet receive direct sunlight, resulting in the four seasons: spring, summer, fall, and winter.
