Water: Zones of the Ocean

The video explores different ocean zones, including the intertidal, neritic, and open ocean. It discusses how factors like sunlight, temperature, and water pressure influence where marine organisms live. The intertidal zone is dynamic, requiring organisms to adapt to changing conditions. The neritic zone is rich in nutrients and marine life, while the open ocean is deep, dark, and less biologically productive, yet home to diverse organisms.

What is a key characteristic of the intertidal zone?

• It experiences changing water levels.

• It is never exposed to sunlight.

• It is located in the deep ocean.

• It is always covered by water.

How do organisms like razor clams adapt to sandy beaches?

• They migrate to deeper waters.

• They attach to rocks.

• They float on the water surface.

• They burrow deep into the sand.

What makes the neritic zone rich in life?

• High water pressure.

• Extreme temperatures.

• Nutrients from the land.

• Lack of sunlight.

Which of the following organisms is commonly found in the neritic zone?

• Anglerfish

• Starfish

• Giant squid

• Deep-sea jellyfish

What is a challenge faced by organisms living in the open ocean?

• High temperatures

• Great pressure

• Abundant sunlight

• Low salinity
