The most likely true statement is that subduction occurs in Location A, and a volcanic eruption may occur in Location B. The Option D is correct.
In Location A, the two horizontal arrows pointing towards each other indicate a convergent boundary where tectonic plates are colliding. The portion of the block on the right moving down suggests that one tectonic plate is subducting beneath the other which is a characteristic feature of subduction zones. This process leads to the formation of deep-sea trenches and volcanic activity.
In Location B, the two horizontal arrows pointing away from each other represent a divergent boundary where tectonic plates are moving apart. The vertical gap in the middle is the mid-ocean ridge where seafloor spreading occurs as magma rises from the mantle to create new crust. This process result in volcanic eruptions along the ridge.
Therefore, subduction is likely happening in Location A, while Location B is characterized by seafloor spreading and the potential for volcanic eruptions.
The Full question is:
The movement of tectonic plates in two different locations is shown below: Two blocks labeled Location A and Location B are shown. At Location A the top layer of the block shows two horizontal arrows pointing towards each other. The portion of this block on the right is shown moving down. The block labeled B Shows two horizontal arrows pointing away from each other. A vertical gap is seen in the middle Which statement is most likely true? Subduction occurs in both locations. Seafloor spreading occurs in both locations. An earthquake may occur in Location A and subduction occurs in Location B. Subduction occurs in Location A and a volcanic eruption may occur in Location B.
