What happened?
209
The rock that
created the
Mexican crater
was 10 km
(6 miles) in
diameter.
Was that all?
The meteorite hit at a time of immense volcanic activity
in what is now western India. This activity would have
sent up clouds of ash and dust that would have blocked
the Sun’s light – just like the effect of the meteorite.
That’s two major events around the same time.
