Volcanoes erupt because of the way heat moves beneath Earth ’s surface. Heat is conveyed from the planet’s interior to its surface largely by convection —the transfer of heat by movement of a heated fluid. In this case, the fluid is magma —molten or partially molten rock —which is formed by the partial melting of Earth's mantle and ...

Rather than a violent explosion, lava pours or flows out. Fatalities from effusive volcanoes are rare because people can usually outrun the lava. However, some people get too close or become trapped ...
