What is eath?

Earth is the third planet from the sun and is the only known planet to support life. It has a diameter of approximately 12,742 kilometers and a mass of 5.97 x 10^24 kilograms. The planet has a diverse ecosystem with a variety of flora and fauna species.

Earth's atmosphere is composed of 78% nitrogen, 21% oxygen, and trace amounts of argon, carbon dioxide, and other gases. The atmosphere helps to regulate the planet's temperature, with the greenhouse effect trapping some of the sun's heat and making life possible.

The planet rotates on its axis every 24 hours, causing day and night, and orbits the sun once every 365.25 days, causing the annual cycle of seasons. The Earth has one natural satellite, the moon, which orbits the planet once every 27.3 days.

Humans have inhabited Earth for thousands of years and have significantly impacted the planet's environment through activities such as deforestation, pollution, and climate change. It is important that we take measures to preserve and protect the planet's biodiversity and ecosystems for future generations.
