Dear MEL Topic Readers,
A massive
asteroid shower hit Earth and the moon 800 million years ago, study says
When was the
last time you took a shower? Unless you’ve been hospitalized for some time, it probably
was hours or a day before. Then, when do you think our planet and the moon took
an asteroid shower? It is believed that about 66 million years ago, a meteor
the size of a mountain slammed into Earth, filling the atmosphere with gas,
dust, and debris that drastically altered the climate, which made dinosaurs went
extinct while some mammals, birds, small reptiles, fish, and amphibians
survived. You probably have known this presumption, haven’t you?
But some
scientists now believe that our planet and the moon were hit by a massive
asteroid shower about 800 million years ago and it might have initiated the ice
age by the massive impact. How do they find such traces? Those researchers
study the moon and asteroid to find what happened so long ago because they
hold a more original state than the earth, where volcanic activities, geologic processes
like erosion, and weathering erase the trace of the past incident. That’s one
of the reasons rockets are sent to the moon and asteroid to bring back the
sample of the ancient trace.
Enjoy
reading the article and learn about how the earth was impacted by asteroids.
