Is volcano the same as a mountain? Explain the differences.

A volcano is a mountain with an opening for magma and gas beneath the Earth to escape. They are formed in the breaks of Earth's crust.

How does a volcanic eruption happen? Explain clearly (use words: pressure, temperature, mantle)

A volcanic eruption happens when the temperature and pressure in the Earth's mantle become too high.

List the Earth's layers from the top to bottom and describe each of their state of matter (liquid, gas, solid).

Crust (solid), Mantle (semi-liquid), Outer core (liquid), Inner core (solid)
