Junior Cycle Geography

The Earth's outer skin, consisting of solid rock between 10km and 60km thick. Crust
At the centre of the Earth, made of nickle and iron with a temperature that reaches over 5000c. Core
Beneath the crust, a layer of molten and semi-molten rock called magma. Mantle
What the Earth's crust is broken into. Plates
Where plates collide, the heavier plates is forced downwards into the mantle where it melts. Destructive boundary
Where plates pull apart molten magma rises up from the mantle forming new crust. Constructive boundary
Where plates slide past each other, and occasionally get stuck. Passive boundary
Describes how the Earth's continents move about as passengers on the plates. Continental drift
The molten or semi-molten material that makes up the Earth's mantle. Magma
The movement of magma caused by the heating and cooling of the material as it moves away from the core. Convection currents
One large landmass formed when all the continents were connected. Pangaea
