Which feature of the ocean floor is observed more than any other feature? Which ocean floor feature is responsible for creating the largest mountain ranges in the world?

Which two ocean floor features are found most closely to the ocean shore?

Which ocean floor feature is responsible for creating new land? Which is responsible for destroying land?

In fact, the tallest mountains and deepest canyons are found on the ocean floor; far taller and deeper than any landforms found on the continents.

Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth.

Underwater landforms · Continental shelf Abyssal plains Mid-ocean ridge Ocean trenches Plate tectonics and the ocean floor Hydrography.

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted. Thus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones.

hope my ans helps

please give brainliest to my answer

be sure to follow me

stay safe

have a good day

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

i think the answer is a, hope this is right, that would be my best guess.
