Discussion Overview

The discussion centers on the conditions of Earth 200,000 years ago, including aspects of continents, climate, and life during that period. Participants explore the geological and environmental context of this time, touching on theories related to ice ages and other geological events.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant suggests that Earth was experiencing a cold climate, referencing ice cores from Greenland as evidence of an ice age.
  • Another participant mentions that volcanic eruptions and potential collisions with asteroids or comets may have triggered ice ages, indicating a possible connection between these events and climate changes.
  • Some participants imply that the original question may relate to a homework assignment or a creative writing project, prompting discussions about the adequacy of research conducted by the questioner.

Areas of Agreement / Disagreement

There is no consensus on the specifics of Earth's conditions 200,000 years ago, as participants present varying viewpoints and hypotheses without resolving the discussion.

Contextual Notes

Some claims are based on interpretations of geological evidence, such as ice cores, while others suggest a need for further research into plate tectonics and continental drift, indicating potential limitations in the original question's scope.

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.
