Question

What is a volcanic eruptioOR is the process of volcano? Explain.

Answer 1

Explanation:

Volcanoes occur when material significantly warmer than its surroundings is erupted onto the surface of a planet or moon from its interior. On Earth, the erupted material can be liquid rock ("lava" when it's on the surface, "magma" when it's underground), ash, cinders, and/or gas.

Answer 2

Volcanic eruption

Explanation:

• A volcano is a vent or fissure in the earth's crust through which the hot lava and volcanic gases are thrown out.
• Volcanic eruption may be either explosive or quiet.
• The earth's upper mantle which is also known as asthenosphere under the crust is nearly molten.
• Magmas originate at this depth.
• They migrate upwards along the faults.
• In, a volcano the magma rises through a opening called vent and reaches the surface as lava.
• At the surface pressure in the rising magma falls, the dissolved gases gets separated out and such a magma is called lava.
