Volcanoes

4. A volcano that will not erupt again
6. Magma that flows out onto the Earth’s surface
8. Molten rock beneath the Earth’s crust
9. A volcano with regular eruptions
10. A low, flat volcano, made from runny lava
12. Differences in temperature of material beneath the plates of the Earth’s crust leads to the creation of currents to transfer the heat. These currents move the plates above them
14. Region created by the action of two tectonic plates colliding and the less dense plate, submerges underneath the denser one
15. A volcanic mudlfow that contains a mixture of rocky debris, ash and water
16. A volcano that hasn’t erupted for many years but activity can be detected inside

1. Type of energy that can be derived from heat within the Earth's crust
2. Plate boundaries where two plates are sliding past eachother in opposite directions
3. Rigid segments of rock that make up the Earth’s crust, they meet at plate boundaries where volcanoes are created
5. Plate boundaries where two plates are moving away from eachother
7. A high, steep-sided volcano made from thick lava
11. Mass movement of rocks and soil down a slope that is often triggered by heavy rain
13. Plate boundaries that move towards eachother and collide
