This "theory" proposed that the Earth's tectonic plates were once joined together as one big landmass called Pangaea, and eventually separated into their present positions.

Where in the mantle are Convection Currents found?

As we move down into the Earth, what happens to the temperature?

From which structure is new ocean floor created?

Old oceanic crust moves sideways from mid-oceanic ridges in a process called Seafloor Spreading. This sideways movement eventually stops because the old oceanic crust gets destroyed. In which structure does old oceanic crust gets destroyed?

In which type of tectonic plate boundary do we find plates sliding past each other?

In which type of tectonic plate boundary do we find plates colliding with each other?

In which type of tectonic plate boundary do we find magma rising to the surface?

In which type of tectonic plate boundary do we find rocks/ crust on either side of the boundary having the SAME age?

Which type of tectonic plate boundary is associated with mountains?

Which type of tectonic plate boundary is associated with volcanoes?

Which type of tectonic plate boundary is associated with the strongest earthquakes and tsunamis?

Observe the diagram of rock layers. Which rock layer is the oldest?

Observe the diagram of rock layers. Which rock layer is the oldest?

This is an area where one tectonic plate dives or moves under another tectonic plate
