Magma is molten rock that lies beneath the Earth’s surface. The temperature of magma is between 650°C and 1100°C. Most of the magma solidifies beneath the Earth’s surface, thus forming Igneous rocks. During a volcanic eruption magma could reach the Earth’s surface, after which it is called lava.
Magma is formed in the Earth’s crust under the influence of very high temperature and pressure. Heat coming from the Earth’s mantle plays a crucial role in this process. How this process exactly works is still not fully understood.
