Is when tectonic plates move towards each other and crunch together. In the picture a Oceanic Plate and a Continental Plate crash together, causing them to bend. This then forms a trench. The bending causes them to slip or break causing the earthquakes.
Is when tectonic plates move away from each other. It causes to make a central valley called a rift. Magma builds up to fill in the crack. Volcanos start to form where the magma is. Earthquakes occur along the faults.
Is when tectonic plates move past each other. They cause many earthquakes. The San Andreas Fault hit San Francisco in 1906. This became the most famous earthquake, because it shook buildings until they crumbled to pieces.
Places where you can find these plate boundaries?
Divergent Boundaries: Mid-Atlantic Ridge
Transform Fault: San Andreas Fault
East Coast of North America vs. Mid-Atlantic ridge
Why do you think this is the case?
What do ocean trenches and plates tectonics have in common?
When a plate tectonic crashes with a oceanic crust it forms a trench. The ocean trench is old crust that gets pushed under the crust. It begins to form mountains under the water that can cause earthquakes, and even volcanos. That's something plate tectonics can create as well.
