Earth is the third planet from the Sun in the solar system and is the only known celestial body to support life. It is characterized by a diverse range of ecosystems, a protective atmosphere, and the presence of liquid water, which covers about 71% of its surface. Earth is composed of various layers, including the crust, mantle, outer core, and inner core. The planet has a unique elliptical orbit around the Sun and rotates on its axis, resulting in the cyclical patterns of day and night as well as the changing seasons. Earth’s environment is influenced by various factors, including geological processes, atmospheric conditions, and biological interactions, making it a dynamic and complex system.
