What is a volcano?
What is a pyroclastic flow?
Identify and explain the factors that affect the force of a volcanic eruption.
The force depends on its viscosity. The viscosity is determined by its temperature and its silica content. The hotter the magma is, the thinner it is and the quieter its eruption. The more silica the magma contains, the thicker it is and the more explosive its eruption.
Volcanic soils are fertile because they contain...
