Magma
Magma explained in an easy to understand way:
Imagine you have a pot of soup simmering on the stove, with bubbles occasionally breaking the surface. This bubbling soup is like magma, which is molten rock simmering beneath the Earth's surface, occasionally making its way to the top. Just as the soup bubbles up because of the heat from the stove, magma rises due to intense heat and pressure from the Earth's interior, waiting for any opportunity to escape, much like the soup bubbles waiting for a gap in the surface to release steam.
