Question

Where on Earth’s surface do you think scientists can locate rocks from the Precambrian era? How do scientists determine the age of the rocks they’re analyzing? What types of tests or analyses do you think scientists would conduct on a rock from the Precambrian era? Lastly, how does understanding the Precambrian era enhance our chances of finding another planet that could one day support life?

Answer 1

Scientists can run tests on the rock samples and find out where the rock is from, how old it is, and what kind of rock it is. With knowing all this information it can help our understand more of how it came to be in that place and in the condition it is in. Since humans were not alive during this period of time, it is difficult to know for sure what happened and if our predictions are correct. If we are able to understand the Precamrrian Era then we are capiable of identifying if another planet is like ours and being formed the same way our planet was created. Being able to identify this would be a big discovery for humans because then we would know what to look for and know if a new found planet could be suitable to support life one day.
