TLDR: Earth is the third planet from the Sun and the only known planet with life. It has a water world with oceans covering most of its surface. Earth's land is home to diverse ecosystems and is shaped by tectonic activity. The atmosphere protects the planet and supports life. Earth has a long history, from its formation to the evolution of life. In the future, Earth's fate is tied to the Sun's evolution.

Earth is a unique planet in our solar system. It is the third planet from the Sun and the only one known to have life. It is often called the "water world" because it has vast oceans that cover about 70% of its surface. The remaining 30% is land, which is home to diverse ecosystems and supports a wide range of life forms.

The planet's land is shaped by tectonic activity, which involves the movement of Earth's crust. This movement creates mountains, volcanoes, and earthquakes. Earth's atmosphere is also crucial for supporting life. It is composed of gases like nitrogen, oxygen, and carbon dioxide, and it protects the planet from harmful solar radiation.

Earth has a long history that spans billions of years. It formed about 4.5 billion years ago from a cloud of gas and dust in space. Over time, the planet's surface cooled and solidified, and water vapor in the atmosphere condensed to form oceans. The first life forms emerged about 3.5 billion years ago, and since then, life has evolved and diversified.

In the future, Earth's fate is tied to the Sun's evolution. In about 5 billion years, the Sun will become a red giant and expand, potentially engulfing the Earth. Before that, Earth's increasing surface temperature may lead to the loss of its oceans and the extinction of many life forms. However, these events are far in the future, and for now, Earth remains a vibrant and diverse planet.
