Earth Planet refers to the third planet from the Sun in our solar system and is the only known celestial body to support life. It has a diameter of approximately 12,742 kilometers and a mass of roughly 5.97 x 10^24 kilograms. Earth is considered a terrestrial planet, consisting primarily of rock and metal. It is positioned within the habitable zone, also known as the Goldilocks zone, where conditions for life are believed to be suitable.
The Earth is composed of several layers, including the solid inner core, the liquid outer core, the mantle, and the Earth's crust, which is further divided into tectonic plates. This dynamic nature of the planet's surface leads to various geological phenomena such as earthquakes, volcanic eruptions, and the creation of mountains.
The Earth is known for its diverse and abundant ecosystems, supporting millions of species, including humans. It has a complex atmosphere primarily composed of nitrogen, oxygen, and trace amounts of other gases, which helps regulate temperature and provides a breathable environment. Earth's oceans cover approximately 71% of its surface and play a crucial role in regulating climate, storing heat, and supporting various forms of life.
The Earth orbits the Sun once every 365.25 days, resulting in the four seasons we experience. Additionally, it rotates on its axis, completing one full rotation every 24 hours, causing day and night cycles. The Earth also has a natural satellite, the Moon, which is an essential factor in tides and influences various aspects of life on Earth.
As the only known planet with confirmed life, the Earth holds immense scientific, ecological, and cultural significance. The study of Earth sciences, including geology, meteorology, and environmental science, aims to understand the planet's processes, natural resources, and sustain
