I think it began as a no animals, humans, including dinosaurs it only has trees until it changed. I don't think so because it says that there were more trees back then than today and the Earth maybe changed like a hot place could have been a warm place many years ago.

9/10 species on earth died away (no more, once dead they don't come back) Earth didn't always look the way it does today.

The life of Earth began with huge bugs/insects because of the oxygen. Almost the entire world was dying and there were certain plants were becoming extinct.

The Earth first started because of the " Big Bang". The Earth didn't look the way it did today because there was more oxygen and Earth slowly started to die off. One out of ten species were extinct. The trees stated to decay and fall over. This happened because of global warming

The Earth on life was different than it is now because 9 to 10 species died and the insect were more larger because there was more oxygen.

The earth didn't look the same with the insects. The dragon flies were the size of eagles. The leaves and plants decompose to put carbon dioxide back into the air. Bacteria killed most of the population of plants and animals. Bacteria was most of the poison that killed most of the land.

There were oversized insects/animals because of oxygen/carbon dioxide.9/10 Animals became instinct on earth. Earth hasn't always looked the way it does now. It began with no humans or animals or plants, and now there are humans ,animals, and plants. That shows how earth began and how it was in the past.

Life began on earth because of the trees made the land and they gave oxygen. No it did not look like today because there was nothing.

Life on earth evolved through time from different animals. Earth didnt always look the same. It used to be one big continent named pangea. There was a continental drift that was caused by earthquakes and it separated into different continents.

The Earth's continents use to be all one huge chunk of land when the dinosaurs lived and the huge chunk was called Pangea. Animals back then were really big for example centipedes were the size of alligators.

The crust on earth is as thin as the skin on an apple. Earthquakes are caused by the random movement by Mother Nature.

An asteroid hit the surface of the earth that caused a species to become extinct.

Humans put so much pollution into the air that most of the atmosphere is just carbon dioxide. We evolved over time.

For photosynthesis you need light and water.Carbon dioxide and fuel that is being put into the earth is effecting our climates.
