Plate tectonics

2. this type of plate boundary sees an oceanic and a continental plate collide
8. this type of plate boundary sees two tectonic plates slide past each other in opposite directions
10. this type of tectonic plate is made of light material and are found under land masses
11. this type of plate boundary sees two continental plates collide
13. these types of hazards are caused by movements of the earth's crust
15. a natural event which is non man-made, and poses risk to life or property
16. this type of plate boundary sees two tectonic plates pull apart
17. this is the inner most layer of the earth. It is a solid ball of nickel and iron

1. this occurs at a destructive plate boundary, where the oceanic plate is forced to sink underneath the continental plate, into the mantle
3. heat that rises and falls within the earth's mantle
4. this is the widest layer of the earth. This layer is made of semi-molten rock called magma
5. this layer surrounds the inner core, and is made of liquid nickel and iron
6. magma that has erupted onto the earth's surface
7. this is the largest tectonic plate
8. this is the outer most layer of the earth
9. these types of hazards are caused by atmospheric changes
12. this type of tectonic plate is made of dense material, and is found under the earth's oceans
14. the point at which two or more tectonic plates meet
