How to make a model volcano erupt is a popular and exciting topic for school science projects because it clearly demonstrates chemical ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...

Volcanoes erupt because hot, melted rock from deep inside the Earth finds a way to reach the surface. This melted rock is called magma, and it forms when parts of the Earth’s mantle become so hot that ...
