Tectonic Plates

PangaeaThe Theory of Pangaea Is that 300 million years ago, all the continents were once connected.

The super continent idea was not accepted by scientist because Wegner did not have enough proof that this had happed such a long time ago.

Pangaea means all lands. The Period in which Pangaea accrued is the Carboniferous Period.

A convergent boundary is an actively deforming region where to plate tectonic plates collide. As a result all the pressure and friction often can cause an earthquake and volcanoes Volcanoes because they collide and it forms when magma finds a pathway to go thru.Convergent Boundary

a linear feature that exists between two tectonic plates that are moving away from each otherIt forms volcanic islands when it moves apart to make gaps which magma moves in and fills up to the top and eventually creates a volcanic island.An example is the Red Sea riftDivergent Boundary

A fault which runs along the boundary of a tectonic plate

It can cause earthquakes

New Zealand's Alpine Fault

6The United States is on the North American Tectonic PlateWhat Plate Do we Live On?

North American

Pacific

Juan de FucaWhat Plates Border the United States

The United States is not in danger due to the tectonic plates moving.If they so happened to move which scientists dont think would happen, there would be safety lines to follow. Are we in any serious danger of hazards related to plate tectonics?

In the futureIn the future, I think the plate tectonics will spread out even farther which will keep causing whats happening in the picture above. If this happens all the continents will be farther apart and maybe even split again.
