In order to calculate this, we simply need to find out how many is 80% of 1500, like this:

So the answer is: 120 volcanoes are located in this area!
Answer:
At convergent boundaries, collisions occur as lithospheric plates move toward each other.
Explanation:
A is not correct because the movement of the tectonic plates is not driven by magnetism.
B is not correct because at this type of boundary the tectonic plates move toward each other, not slide past each other.
C is not correct because the plates move toward each other at this type of boundary, not move away from each other.
D is correct because at this type of boundary the plates move toward each other, and as they do collisions occur, resulting in the formation of mountains and subduction zones.
Answer:
Because the Earth is not getting bigger, an equal area of crust must be destroyed in order for the new basaltic crust to form. This takes place at subduction zones, where the denser basaltic rock gets shoved underneath less dense continental crust.
Explanation:
Younger as the sedimentary rock was likely deposited on top of the igneous rock and the scattered pieces are parts of the igneous rock that had been eroded prior to deposition and lithification of the sedimentary rock
