Ocean trenches are the deepest parts of the ocean. They border continents or island arcs where tectonic plates come together.

Deep ocean trenches are evidence for?

Deep ocean trenches are evidence for plate tectonics, showing where one tectonic plate is subducting beneath another. These trenches form at convergent boundaries when the denser oceanic plate sinks into the mantle. The presence of deep ocean trenches also indicates areas of seismic activity and potentially tsunamis.


What are deep ocean trenches associated with?

Deep ocean trenches are associated with tectonic plate subduction, where one tectonic plate is forced beneath another into the mantle. This process leads to the formation of deep-sea trenches, which are the deepest parts of the ocean floor. Trenches are often sites of intense seismic activity and can also be locations where volcanic arcs form.


What percentage of the ocean bottom is covered by trenches?

Approximately 2.5% of the ocean bottom is covered by trenches, which are deep depressions in the ocean floor that form where tectonic plates collide and one plate is forced beneath the other. These trenches can be incredibly deep, with the Mariana Trench being the deepest known point in the ocean.


Explain what plate tectonics and ocean trenches have in common?

Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)


What are 2 geological features that can occur at plate boundaries?

Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
