Question

What characteristic of a slab of oceanic lithosphere leads to the formation of deep-ocean trenches instead of shallow trenches

Answer 1

Answer:

Densidad.

Explanation:

The greater the density of an oceanic lithosphere plate, the greater the weight of that plate. This will affect the degree of subduction of that card. The higher the density, the greater the degree of subduction and the ability of the plate to descend, forcing the creation of prominent and well-defined trenches on the ocean floor.

The density of the plaque increases as the age of the plaque increases, so we can consider age, another factor in the formation of these trenches.
