- There's 2 types of volcanoes, dormant
- People live near the volcano because it has fertile land?
- convection currents in the magma

- Volcanoes are cone shaped mountains that’s contain lava
- Formed when the crust of the Earth opens
- Plate tectonics occur when there is friction

volcanoes are dangerous, causes damage to areas around it
to measure volcanoes : seismographs
the higher up the scale, the stronger the shock.

# data[].attributes.body
- Volcanoes are usually cone shaped mountains.
- When magma reaches the Earth's surface it's called lava.
- When lava cools, it forms rock.
- Volcano eruptions can happen at destructive and constructive boundaries.
- The magma chamber is a collection of magma inside the Earth.
- The main vent is the main place where magma escapes.

# data[].attributes.body
-Volcanoes are formed when magma from the earths upper mantle works its way to the surface.
-Earthquakes happen when there is friction between tectonic plates
-Earthquakes can set off volcanoes
- Plinian eruptions are the most dangerous (Mt Vesuvius)
