Question

It seems like millions of years ago there were lots of really active volcanos. Why is that no longer the case?

In: Planetary Science

Answer 1

nowadays, there are more than 1500 active volcanoes on Earth

and around 50–70 volcanoes erupt every year

now multiply THAT number with *”millions of years”*

and you see that it’s easy to *think* there were

many more vulcano’s erupting back then
