AI Thread Summary
Determining whether an object is not from Earth involves analyzing its composition and characteristics. Meteorites serve as a primary example, as they can be identified through specific tests that reveal their extraterrestrial origin. For instance, lunar rocks, which are collected from the Moon, are studied to confirm their non-Earth origins. Resources like the Washington University in St. Louis provide detailed methodologies for such analyses, emphasizing the importance of scientific testing in distinguishing between terrestrial and extraterrestrial materials.

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
