Features of the Ocean Floor Quiz

Study Notes

Main Features of the Ocean Floor

Eight primary features include: continental shelf, continental slope, continental rise, abyssal plain, mid-ocean ridge, ocean trench, seamount, and volcanic island.

Continental Shelf

A submerged plain located between a continent and the ocean, characterized by a gentle slope.
Acts as an extension of the continental landmass beneath the sea.

Continental Slope

A steep underwater gradient extending from the edge of the continental shelf down to the continental rise.
Marks the transition to deeper ocean areas.

Continental Rise

A gently sloping area located between the continental slope and abyssal plain.
Acts as a sediment accumulation zone.

Abyssal Plain

Flat, vast regions on the deep ocean floor, often found at the base of continental rises.
Considered one of the most level and smooth zones on Earth.

Mid-Ocean Ridge

A significant underwater mountain range formed by tectonic activity at divergent plate boundaries.
Plays a crucial role in the process of seafloor spreading.

Ocean Trench

A deep, narrow depression in the ocean floor located at subduction zones.
Represents some of the deepest parts of the Earth's oceans.

Seamount

An underwater mountain formed by volcanic activity, rising from the ocean floor.
Not tall enough to emerge above sea level.

Volcanic Island

Landforms created by volcanic activity that were once seamounts.
Can emerge above the ocean surface, often becoming prominent land masses.
