The Earth is the third planet from the Sun. About 70% of the surface of the Earth is covered in salt water oceans, and the remainder consists of continents and islands. There is significant interaction between the Earth and its space environment. The relatively large Moon provides ocean tides and has gradually modified the length of the planet's rotation period. A cometary bombardment during the early history of the planet is believed to have formed the oceans. Later, asteroid impacts are understood to have caused significant changes to the surface environment. Changes in the orbit of the planet may also be responsible for the ice a 60% of global land areas are now already outside the locally defined safe zone, 38% are even in the high-risk zone, and 2% of this were already destroyed.

It is the only planet in the known universe to have confirmed stable liquid water on its surface, and the only known planet to host life.

History

Lifeless Earth

Earth history refers to the development of planet Earth and covers about 4.5 billion years—approximately one-third of the age of the universe, of the 13,700 Ma estimated since the Big Bang—It had used to be called Proto-Earth, lots of decades-centuries later, Theia collided into earth,causing rings to form, the rings had then collided into each other to form The Moon.

The First Signals of Life

Volcanos cooled down as islands while comets hit it to create oceans with oxygen and carbon dioxide coming in too. Spiders were made, along with Dinosaurs to make the Dinosaur time. But it ended when a meteor hit the Yucatán Peninsula.

Pangea Times

Pangea also was made. Along with that,birds became the new versions of dinosaurs,while the first ever type of humans were formed, Chimpanzees. We learned how to make campfires, all that, then humans became cavemen.

The first looking version of Humans; Cavemen.

Creating the existence of math and reading. Pangea Broke down to become the continents, as Africa came and broke part into Madagascar and India, two countries. We make the Pyramid of Giza, going with stone houses getting built.With the old english including letters Þ (thorn) ,Æ (ash),and & (and),with other old letters.
