AI Thread Summary
Around 200,000 years ago, Earth was experiencing one of its frequent ice ages, characterized by colder temperatures and extensive glaciation. Research indicates that volcanic eruptions and potential asteroid or comet collisions may have triggered these ice ages. The discussion suggests that understanding plate tectonics and continental drift is essential for grasping the geological context of that time. Ice core samples from Greenland provide compelling evidence of the climate conditions during this period. Overall, the Earth was significantly different, with a landscape shaped by glacial activity and geological events.

in terms of continants, life, etc

thanks in advance

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:
 
thanks i'll stop bugging you all..;)
 
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.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
