Unit 2: Ocean Zones Review

Front

What is the intertidal zone?

Back

The intertidal zone is the area between the high tide and low tide marks, where the ocean meets the land.

Front

What is the pelagic zone?

Back

The pelagic zone is the largest life zone in the ocean, encompassing the open water column away from the coast.

Front

What is the photic zone?

Back

The photic zone is the portion of the marine biome that is shallow enough for sunlight to penetrate, allowing photosynthesis.

Front

What is the hadalpelagic zone?

Back

The hadalpelagic zone is the deepest part of the ocean, home to the deepest trenches, characterized by high pressure and low temperatures.

Front

What is bioluminescence?

Back

Bioluminescence is the ability of certain organisms to produce light through chemical reactions, often used for hunting or communication.

Front

What defines the abyssopelagic zone?

Back

The abyssopelagic zone is a deep ocean zone characterized by complete darkness, high pressure, and cold temperatures.

Front

What is the difference between the neritic zone and the oceanic zone?

Back

The neritic zone is the coastal area where sunlight penetrates, while the oceanic zone is the deeper part of the ocean beyond the continental shelf.

Front

What organisms are typically found in the benthic zone?

Back

The benthic zone is home to organisms that live on or near the ocean floor, including crabs, starfish, and various types of fish.

Front

What adaptations do organisms in the bathypelagic zone have?

Back

Organisms in the bathypelagic zone often have adaptations like bioluminescence and large eyes to navigate in darkness.

Front

What is the significance of the photic zone for marine life?

Back

The photic zone is crucial for marine life as it supports photosynthesis, providing energy for the entire oceanic food web.
