- Magma rises - Collects inside magma chambers underneath a volcano - Pressure builds in the magma chambers as they fill - Gain energy for eruption - Some of the energy is converted into seismic activity (earthquakes) - If the magma building in the volcano is thick and sticky it will trap gases - Results in an explosive eruption when the pressure becomes too intense - If the magma is thin and runs - The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption - What might be the first step of the process?
Ans: Magma is formed when rock melts inside the Earth's crust
