How do volcanic eruptions work?

154 views

I suppose I either read or was told, somewhere in early childhood, that volcanoes go *boom* and explode, which for some reason just stuck and I never bothered to re-check. (thinking back on it, I was probably being told about Pompeii, where it did kinda go *boom*)

With footage of Mauna Loa all over the place..that does not look like what kid-me thought a volcanic eruption did.

Do different types of volcanoes erupt differently? Do none erupt like kid-me was told they do?

Volcanic eruptions happen when molten rock (called magma) builds up pressure beneath the Earth’s surface and is forced out. Magma rises from deep within the Earth and is usually very hot. When it reaches the surface, it is called lava, which can be extremely dangerous. Lava can flow out of the volcano and cause destruction in its path. Volcanic ash, smoke, and gases are also released during an eruption.
