What was earth like 200,000 years ago?

In summary, the conversation revolves around the topics of continents, life, and the history of planet Earth. The individual asking the question is looking for information on these subjects for a sci-fi story they are writing, and others suggest doing research on plate tectonics and continental drift. The conversation also touches on the topic of ice ages and their possible triggers.

Sounds like a homework question. What research have you done?

Ah. A review of your past posts suggests you're writing a sci-fi story.

Still, a quick wiki of plate tectonics or continental drift would probably be better than having to give us all credit in your book for doing your basic research for you. :biggrin:

Cold is the short answer. Ice cores from Greenland are pretty compelling. Earth was in one of its frequent ice ages back then. Volcanic eruptions, and possibly collisions with asteroids/comets, appear to trigger ices ages.
 

1. What was the atmosphere like 200,000 years ago?

The atmosphere 200,000 years ago was significantly different from what it is today. It was composed mainly of carbon dioxide, methane, and water vapor. The levels of these gases were much higher than they are now, creating a much warmer climate.

2. Did humans exist 200,000 years ago?

Yes, humans did exist 200,000 years ago. The earliest known Homo sapiens fossils date back to around 300,000 years ago, and evidence suggests that humans were living in Africa 200,000 years ago.

3. Were there any major geological events 200,000 years ago?

There were several major geological events that occurred 200,000 years ago. The most significant was the beginning of the last glacial period, which lasted until around 11,700 years ago. This period saw large ice sheets covering much of North America, Europe, and Asia.

4. What type of animals lived on Earth 200,000 years ago?

During this time, Earth was home to a diverse range of animals, including early humans, woolly mammoths, saber-toothed cats, and giant sloths. Many of these animals are now extinct.

5. How has Earth changed since 200,000 years ago?

Since 200,000 years ago, Earth has undergone significant changes, both geologically and biologically. The last glacial period ended, leading to a warmer climate, and the rise of modern human civilizations. The extinction of many species has also occurred, while new species have evolved and thrived.
