Question

shaping the land
dr. achebe is in charge of a deep - sea exploration off the atlantic coast of western africa. the teams remotely operated underwater vehicle has been exploring several trenches and ocean ridges in the area. along which type of tectonic boundary is dr. achebe and the team operating?
transform boundary convergent boundary eroded boundary divergent boundary

Explanation:

• Transform boundary: Involves lateral sliding of tectonic plates, not typically associated with trenches and ocean ridges.
• Convergent boundary: Where plates collide. Ocean - trench is a feature (e.g., Mariana Trench at a convergent boundary between oceanic and continental or two oceanic plates). But ocean ridges are not formed here.
• Eroded boundary is not a standard tectonic boundary type.
• Divergent boundary: Mid - ocean ridges are formed here as magma rises to fill the gap when plates move apart. Trenches can also be associated (in some complex plate - interaction scenarios near divergent boundaries in oceanic - oceanic settings where one plate starts to subduct slightly due to density differences etc., though mid - ocean ridge is the more prominent feature).

Answer:

divergent boundary
