What causes mountain to erupt?

Volcanoes erupt when molten rock called magma rises to the surface. As the magma rises, bubbles of gas form inside it. Runny magma erupts through openings or vents in the earth’s crust before flowing onto its surface as lava. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.

What would happen if Mount Everest fell into the ocean?

If you cut Mount Everest off at sea level and put it on the ocean bottom in the Challenger Deep, there would still be over a mile of water over the top of it. This movement creates a trench where the descending oceanic plate drags down the edge of the overriding plate.

What happens if Mount Everest melts?

The report from the International Centre for Integrated Mountain Development says that if global warming continues, two-thirds of Himalayan glaciers could melt by 2100 and that the melting ice could cause major floods and destroy crops.

Can a mountain turn into a volcano?

A mountain is very unlikely to turn into a volcano. Those mountains, are created by volcanoes! After those volcanoes erupt, scientists say that it will be very unlikely for those retired volcanoes, to erupt again. The rock that is formed after the volcano has erupted, is called basalt.

What do lava tubes do?

These underground passageways, also known as pyroducts, are created by lava flows themselves and are capable of transporting great quantities of lava long distances underneath the surface. When the supply of lava stops at the end of an eruption, or if it gets diverted elsewhere, it leaves behind an empty cave.

How could you find out if a mountain is a volcano?

A mountain is formed due to various geological processes like movement and opposition of tectonic plates but a volcano is formed around a vent that allows magma to reach the surface of the earth. It all has to do with plate tectonics.
