1. The diagram below shows three plates (A, B, C). Plate B is denser than Plates A and C.
A continent is shown on Plate C, along with seafloor. The other plates are entirely seafloor. The arrows show the directions that the plates are moving.
Complete the table. First, note the geologic feature(s) that corresponds to each number on the map. Then explain in detail how the plate movements at each location account for the features at that location.

Answer:
Number on Map
Feature(s)
Explanation
1
islands
Islands are convergent boundaries because the plate B goes toward the direction of the plate A, this collapse creates what we call islands.
2
trench
This trenches are convergent boundaries because the plates B goes toward the direction of plate A, the result of these collapse is what we call trenches.
3
rift valley
The movement of the plates A and C is a divergent plate boundary, which are two tectonics plates that move away from each other. What happens in rift valleys is that materials rise from beneath the earths surface.
4
trench
The movement of the plates B and C is a convergent plate boundary, because the two plates are moved together. What happens at trenches is that the lithosphere is pulled into the asthenosphere.
5
volcanoes and mountains This type of plate collapse is a convergent boundary. When the plates crashes, it creates a hot spot in the center, which is the cause of the creation of mountains that come out of the oceans, which we call volcanoes.
