* Molten: This means the rock is extremely hot and liquid.

* Rock: Lava is composed of various minerals and rocks that have melted due to intense heat.

* Expelled from a volcano: Lava originates from the Earth's mantle and is forced out through volcanic vents.

* During an eruption: Lava flows are a hallmark of volcanic eruptions, a powerful release of energy from the Earth's interior.

Here's a simple analogy: Imagine a pot of boiling water on the stove. The boiling water is like the lava, and the stove is like the volcano.

Lava is fascinating because it is a powerful force of nature that can shape the Earth's landscape. It is also a source of valuable minerals and resources.
