Mr. D's Ocean Floor Features Challenge

Front

What is a Trench?

Back

A trench is a deep, narrow depression in the ocean floor, often formed by the subduction of one tectonic plate beneath another.

Front

What is a Mid-Ocean Ridge?

Back

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

Front

What is a Rift Valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often associated with volcanic activity.

Front

How is an ocean trench similar to a canyon?

Back

Both an ocean trench and a canyon are deep, narrow landforms, but a trench is found underwater while a canyon is on land.

Front

What is a Continental Shelf?

Back

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

Front

What is a Continental Slope?

Back

The continental slope is the steeply sloping area between the continental shelf and the deep ocean floor.

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.

Front

What is an Abyssal Plain?

Back

An abyssal plain is a flat, deep area of the ocean floor, typically found at depths of 3,000 to 6,000 meters.

Front

What is a Volcanic Island?

Back

A volcanic island is an island formed by volcanic activity, often resulting from the eruption of underwater volcanoes.

Front

What is the process of subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often forming trenches.
