Seamounts and Their Ecological Impact

The video explores seamounts, isolated mountains rising from the ocean floor, and their role in disrupting ocean currents. These underwater structures create unique ecosystems, attracting diverse marine life, including predators like tuna. Seamounts act as oases in the open ocean, providing rich feeding grounds. The Pacific Ocean hosts over 10,000 seamounts, with many more yet to be discovered.

What are seamounts?

• Isolated mountains rising from the ocean floor

• Deep-sea trenches

• Underwater volcanoes

• Coral reefs

How do seamounts affect ocean currents?

• They create whirlpools

• They have no effect on currents

• They disrupt the smooth flow of currents

• They stop the currents completely

What role do seamounts play in marine ecosystems?

• They are primarily used for human exploration

• They are only home to large predators

• They support diverse marine life by bringing plankton to the summit

• They are barren and lifeless

Which creatures benefit from the plankton brought to seamount summits?

• Only deep-sea creatures

• Only large fish

• Corals, sponges, and various fish

• Only surface-dwelling fish

How does the life around seamounts compare to the open Pacific Ocean?

• There is no life around seamounts

• It is more abundant

• It is equally abundant

• It is less abundant

Approximately how many seamounts are there in the Pacific Ocean?

• Exactly 10,000

• More than 10,000

• Less than 1,000

• Around 5,000
