plate movement!
Hey this is the plate movement page. There are three ways the plates can move. Convergent, divergent and transform. If you want to find out more about those three movements, you have to scroll down!!!
Convergent boundaries
Convergent boundaries are when plates crash or crunch together. The plates only move a few centimeters each year, so it takes millions of years for plates to collide. In the image to the left, an oceanic plate has crashed into a continental plate.
divergent boundaries
Places where plates are moving apart from each other are called divergent boundaries. When the earth's brittle surface layer called the lithosphere is being pulled apart, it breaks along parallel faults that tilt a lttle bit outward from each other. As the plates separate along the boundary, the block between the faults cracks and drops down into the soft and plastic interior called the asthenosphere.
transform boundaries
Places where plates slide past each other are called transform boundaries.
The plates push against each other and using the force, they slowly slide past each other. When the two plates finally release, it releases energy and creates an earthquake.
For example: Use your hand and push them against each other side by side with your palms facing down. Push your hands in two different directions, and finally release them. Did you feel the force? If you did, that is what is happening under your feet right now slowly.

the theory of pangea
This theory was created by Alfred Wagener, in December 1910. Wageners hypothesis was that at one point all of the continents were all part of one super continent called "Pangea". The evidence came from the shape of the land, fossils, landforms and the ancient ice age. The shape of the land was South America and Africa. Matching plant and animal fossils have been found on different sides of the ocean. The landforms are like mountains ranges and rock formations match on different continents.
