Volcanoes

When the Earth's crust melts, magma is formed. Magma builds up high-pressure fast, and needs somewhere to escape, and the hole at the top of a volcano is the easiest place to do this. This is called a volcanic eruption. When magma and rock bursts out of a volcano, it's called lava.

Volcanologists use many different tools to measure volcanic eruptions, such as seimometres!
