Earths Crust |
Earths crust is broken up into separate plates ,Seven large and seven small , they fit together like a jigsaw , floating on magma in the mantle , they meet at plate boundaries., Ireland lies on the Eurasian plate. |
|
|
|
Colliding Plates |
When two plates collide , they build up huge pressure . plates would be forced down into mantle , where it melts , Destructive boundary. |
Nazca and American Plates |
|
|
Plates that Pull apart |
When plates pull apart, magma rises from mantle , where it cools and new crust is formed called a constructive boundary. |
Eurasian and African Plates |
|
|
What is Continental Drift ? Why do the plates move on top of the mantle? Name 5 plates? Name differences between plate collision and pulling apart? What was earths landmass called?
|
1 : The breaking apart of landmasses , e.g Europe is moving away from america (very slow) 2: The very hot core heats magma in mantle , this sets up convection currents , magma moves upwards from core to crust , cools and sinks back to core so it can start again 3: Eurasian , American , Pacific , African , Indian 4: Collision causes destruction because some crust is destroyed (melts) ( earthquake ) 5: Pangaea 6:Only known planet to store life 7:A: one tenth B :6 billion C: one eighth D : two thirds E: one quarter |
