Volcanoes

A boy and two girls are standing around a exhibit that has a yellow and blue information panel at the back. In the centre of the group is a model volcano.

Magma underground is released through volcanic vents to flow as lava above ground.

How it works

Move the knob and watch how simulated strips of 'lava’ build a mountain.

Things to try or ask around the exhibit

How do some volcanoes form mountains?

Background

Some mountains form when lava flows out from volcanic vents. When lava is stored deep underground, it is called magma. Once the magma travels up and out through a volcano’s vent, it is called lava! As each wave of lava spreads out around a volcano’s vent, it cools down and sets hard. As more layers of lava flow out and cool down, they create mountains on continents and on the ocean floor.

Finding the science in your world

Villages surrounding extinct and active volcanoes tend to have productive agricultural lands, because volcanic deposits create nutrient-rich soils that generate healthy crops.
