Chapter 1 Earth Structure And Plates Flashcards
What’s the small movement of plates each year called?
Continental drift
Name the different layers of the earth
Inner core,outer core,mantle,crust
Explain plate tectonics
It’s the study of plate movement and their effects
E.g folding,volcanoes,earthquakes,faulting
What are plate boundaries
The lines where plates edges meet
Explain plates slide past each other
When plates push or slide past each other pressure builds up before the plates move. This movement causes earthquakes
Explain plates separate
When to plates separate magma enters through the cracks and forms volcanoes. Mid ocean ridges are formed and new land is added. This is constructive plate boundary.
What are convection currents
They are caused when plates in the mantle move magma is heated by the core and hot currents rise up and join or separate this causes plates to join or separate
What was the huge landmass called that covered the continent
Pangaea
