Answer:

6.) The San Andreas Fault

The San Andreas Fault is one of the most intensely studied faults on the planet. It is a continental transform that separates the Pacific plate from the North American plate along its entire trace. The trace of the fault through California is shown in Figure 17.1.

7.) Subduction occurs .when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth's interior Not all convergence leads to subduction. Continental rocks are too buoyant to be forced downward, so when continents collide, they crumple but stay at the surface.

8.) Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. Sometimes, the two tectonic plates press up against each other, causing the land to lift into mountainous forms as the plates continue to collide.

Hope this helps!
