These concepts are VERY important.
Think about these questions as your watch the videos and read the text. You should be able to answer them by the time you are finished with this page.
The two videos below will help you understand how tectonic plates move, the different types of plate boundaries, and the types of land forms that occur at each type of boundary.
Key information for plate boundaries:
There are 3 types of convergent boundaries.
Oceanic to Continental Continental to Continental Oceanic to Oceanic
Subduction happens at convergent boundaries. Subduction is when one plate is pushed under another plate.
At convergent boundaries, tectonic plates are moving towards each other. Here, you will find...
Divergent boundaries develop like the image below.
At divergent boundaries, tectonic plates are moving away from each other. Here, you will find...
Transform boundaries are tectonic plates slipping beside each other.
At transform boundaries, you will find "disconnected" land forms; land forms that were once together but are now disconnected, like the river in the above picture.
If you can remember which way the plates are moving at each boundary, then you will do just fine!
Also, remember that convection currents cause the plates to move and are the reason there are ridges and rifts at divergent boundaries and trenches, mountains, and volcanoes at convergent boundaries.
