The mantle makes up 84 percent of Earth’s volume, and though it’s solid rock, over the course of millions of years, it behaves like a liquid. The crust is made of giant blocks called tectonic plates that slide on top of the mantle, which can reach temperatures of 3,700 degrees Celsius. 1) How volcanoes form, and what makes them eruptĪ volcano is what happens when the earth’s crust leaks and molten rock squirts through.
