Question

Accepted Answer

Aleutian and Mariana trenches are formed along with:

**Option 2: Convergent Plate Boundaries** is the correct answer because:

*   **Trench Formation at Convergent Boundaries:** Trenches are deep, narrow depressions in the ocean floor. They are specifically formed at convergent plate boundaries where one tectonic plate subducts (slides) beneath another. The Aleutian and Mariana trenches are prime examples of this process. The Mariana Trench, in particular, is the deepest part of the world's oceans, formed by the subduction of the Pacific Plate beneath the Mariana Plate. The immense pressure and bending of the subducting plate create the trench.

**Why the other options are incorrect:**

*   **Option 1: Divergent Plate Boundaries:** Divergent plate boundaries are where tectonic plates move *apart* from each other. This separation creates rifts and mid-ocean ridges, where new crust is formed. Trenches are not associated with this type of boundary.

*   **Option 3: Transform Fault Plate Boundaries:** Transform fault plate boundaries are where plates slide horizontally past each other. This movement causes earthquakes, but it does not create the deep depressions characteristic of trenches. The San Andreas Fault is a classic example of a transform fault.

*   **Option 4: Conservative Plate Boundaries:** Conservative plate boundaries are another name for transform plate boundaries. As explained above, these boundaries do not create trenches.
