Transfrom
A transform boundary occurs where two plates slide against each other. The plates build up tension, then release the tension with a spurt of movement. This movement is felt as an earthquake. Places were plates slide past each other are called transform boundaries. Since the plates on either side of a transformation boundary are merely sliding past each other and not touching or tearing each other apart.
Convergent
A convergent boundary occurs when two plates come together and when they come together they either create a volcano, earthquake or a mountain range depending on the area of the collision. The collisions are very slow and last millions of years. The other name for this is a subduction zone
Divergent
Divergent boundary is also known as a spreading boundary. A divergent boundary is when two plates move away from each which allows lava to fill where the plates were. The plates act like to cars moving super slow. Other when the two plates split it forms a new plate from the lava in the mantle. Where a divergent boundary crosses the land, The rift valleys which form are typically 30 to 50 kilometers wide. Where a divergent boundary crosses the ocean floor
the rift valley is much narrower. Only a kilometer or less across, and it runs along the top of a mid oceanic ridge. Oceanic ridges rise a kilometer or so above the ocean floor and form a global network tens of thousands of miles long( Ex: the Mid-Atlantic ridge). Plates separation is a slow moving for example divergence along the Mid Atlantic ridge. The Atlantic Ocean to widen at only about 2 centimeters per year. Is continental drift making the plates crack? If the Atlantic ocean gets two centimeters bigger every year doesn’t that mean that the continents are moving to?

The Theory of Pangea
The theory is that a long long time ago the earth was one big peice of land but through out the hundreds and hundreds of years the plates moved away from each other. The evendence is that scientist found fossles on other country's that couldn't have swam thier and how all the contenents fit together like one big puzzle piece.
