Marine Science Final Exam Review

Front

Phytoplankton

Back

Phytoplankton are microscopic marine plants that produce roughly 50%-55% of the oxygen on planet Earth through photosynthesis.

Front

Seismic sea waves

Back

Seismic sea waves, also known as tsunamis, are caused by underwater explosions, earthquakes, and landslides.

Front

Beluga whale

Back

The Beluga whale is known as the 'canary of the sea' due to its wide range of vocalizations and communication abilities.

Front

Swim bladder

Back

Sharks lack a swim bladder, which is an organ that helps many fish maintain buoyancy.

Front

Continental margins

Back

Continental margins are the zones of transition between the land and the ocean, classified as either passive or active margins.

Front

Passive margins

Back

Passive margins are typically found along the Atlantic Ocean and are characterized by low seismic activity and little volcanic activity.

Front

Active margins

Back

Active margins are usually located along the Pacific Ocean and are associated with high seismic activity and volcanic activity.

Front

Oxygen production in oceans

Back

The oceans, primarily through phytoplankton, contribute to more than half of the Earth's oxygen supply.

Front

Tsunami causes

Back

Tsunamis can be triggered by underwater earthquakes, volcanic eruptions, or landslides.

Front

Marine ecosystems

Back

Marine ecosystems include various habitats such as coral reefs, estuaries, and open ocean, each supporting diverse marine life.
