Ocean Floor Features

Front

What is a volcanic island?

Back

A volcanic island is an island formed by volcanic activity, typically arising from underwater volcanoes that erupt and build up over time.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where tectonic plates are moving apart and magma rises to create new oceanic crust.

Front

What is the continental shelf?

Back

The continental shelf is the submerged border of a continent, extending from the shoreline to the continental slope, characterized by shallow waters.

Front

What is the order of seafloor features from the shoreline to the deep ocean?

Back

The order is: Continental shelf – continental slope – continental rise – mid-ocean ridge.

Front

True or False: Volcanoes can be found on both land and underwater.

Back

True.

Front

What is the continental slope?

Back

The continental slope is the steeply sloping area that connects the continental shelf to the deep ocean floor.

Front

What is the continental rise?

Back

The continental rise is the gently sloping area at the base of the continental slope, where sediments accumulate.

Front

What are ocean trenches?

Back

Ocean trenches are deep, narrow depressions in the ocean floor, often formed at convergent plate boundaries where one plate is subducted beneath another.

Front

What is the abyssal plain?

Back

The abyssal plain is a flat, deep-sea floor area that lies at depths of 3,000 to 6,000 meters, characterized by a lack of features.

Front

What is a seamount?

Back

A seamount is an underwater mountain formed by volcanic activity, rising from the ocean floor but not reaching the surface.
