LESSON 14.11 What are the types of volcanoes and how do they erupt?
LEARNING INTENTION By the end of this lesson, you should be able to: • describe the different types of volcanic landforms • explain why volcanoes have different shapes and how they erupt.
Tune in Look closely at FIGURE1 . In the area around the erupting volcano, you can see the lights of a built-up area.
FIGURE1 An erupting volcano in Spain
1. Suggest why people would be living so close to an erupting volcano. 2. Describe what you can see being erupted. What impact might it have on the surrounding land?
Volcanic mountains are formed when magma pushes its way to the Earth’s surface and then erupts as lava, ash, rocks and volcanic gases. These materials build up around the vent through which they erupt. A volcanic eruption can be slow or spectacular, and can erupt in a variety of different ways (see FIGURE1 ).
