A section of the lithosphere that slowly moves over the asthenosphere, carr
2
Subduction is when...?
One plate slides under the other
New islands are formed
New crust is formed
Earthquakes along a boundary
3
What is a divergent boundary?
Where two tectonic plates are moving towards each-other
Where two boundaries are moving away each-other
Where two tectonic plates are moving past each-other
4
Pangea can be proved by...
climate evidence (proof of a different climate in the past than now)
fossil evidence (similar remains of animals and plants across several areas
rock evidence (mountain chains that are similar and could connect)
mid-atlantic ridge (caused by the same thing that caused it to seperate)
5
What Causes Plate Tectonics?

Volcanoes
Weather
Earthquakes

10
What is Continental Drift?
The theory that the continents move
large sections of the earth crust
the boundary of continents colliding
the cycle of heating, rising, cooling and sinking
11

The process by which iron particles in lava erupted and aligned
13
Which is not evidence for continental drift?
Glaciation
Magnetic rocks that all pointed the same way
Matching mountain ranges
Same fossils found across continents
14
Plate Tectonics
gave rise to today's continents
by convection currents in the mantle.
