How was Earth formed?

Earth was formed by Rocks and dust put together by gravity!

Early earth is the movement of rocks,plants,cavemen,mountains,dinosaurs,and animals. It was inhospitable because of how hot it was.

Well what is it and how was it back then?

The Precambrian Era started about 3.5 billion years ago and made up 87% of earths history. This era was important because organisms developed the ability to photosynthesize 2.7 billion years ago like sponges,jellyfish,and other single celled organisms

Early earth was made up of Era's and time periods could you explain what were those events?

Precambrian Era

The Paleozoic era lasted until about 245 million years ago but started about 358.9 million years ago. Life began to diversify and the fossil records show many different types of plants and animals. Vertebrates and invertebrates developed during this era!! The Paleozoic era held the largest mass extinction on fossil record

90% of marine life extinct

70% of land species went extinct

The mesozoic era started about 251 million years ago and ended about 66 million years ago. This is the era where much larger and complex organisms like dinosaurs,mammals, and birds developed during this era.

This is the era where the mass extinction of dinosaurs occurred and separation of continents.
