Question

Which environmental changes occur faster?

A. volcanic eruption

B. regrowth of forest after volcanic eruption

Answer 1

Volcanic eruption ==> A volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust... The largest eruptions come from volcanoes called rhyolite calderas, and these huge eruptions may occur at intervals of """10,000 to 30,000 years"""". Yellowstone, the largest caldera in the U.S.A. seems to erupt on average every 600,000 years!

Regrowth after volcanic eruption ==> If a plant or area comes in contact with lava or debri from a volcanic eruption, it could take """20 or so years""" for anything to even start growing...

So option B is fast occurring natural change.... @♥Ashley♥
