Final answer:
Location A, where tectonic plates move away from each other, likely features the formation of a mid-ocean ridge due to divergent boundaries, while Location B, where plates collide and one subducts beneath the other, likely experiences the creation of a trench and volcanic activity.
Step-by-step explanation:
When looking at the movement of tectonic plates at Location A, where plates move away from each other, we are observing a divergent boundary. This can lead to the creation of new crust as magma rises to fill the gap and cools, forming new lithosphere. This is often seen in the mid-ocean ridges such as the Mid-Atlantic Ridge. On the other hand, at Location B, where tectonic plates collide, one of the colliding plates is forced beneath the other in a process known as subduction. This typically results in the formation of a deep ocean trench and volcanic activity due to the melting of the subducting plate.
Therefore, the most likely correct statement about these locations would be that at Location A, a mid-ocean ridge is likely forming, while at Location B, there could be a formation of a trench accompanied by volcanic activity.
