Copernicus believed planets moved at uniform speeds around the Sun and were affected by retrograde motion.
<span>Earthquakes occur in the crust or upper mantle, from the earth’s surface to about 400 miles below the surface. But the very deepest earthquakes only occur at subduction zones where cold crustal rock is being pushed deep into the earth. In California, earthquakes are almost all in the top 15 miles of the crust, except in northern California along the Cascadia Subduction Zone, which extends into Oregon, Washington, and British Columbia.</span>
Answer:
The teacher is demonstrating a convergent plate boundary.
Explanation:
A is correct because this type of boundary is characterized by two or more plates moving toward each other and pressing each other, with the smaller ones gradually moving below the larger ones.
B is not correct because the earthquakes are a consequence of the plate boundaries and their activity.
C is not correct because the equator is simply an imagined line that is separating the northern and southern hemispheres.
D is not correct because the divergent plate boundaries are the ones where the plates are moving away from each other.
