Seafloor

During a marine biology class, Priya was asked to identify the part of the ocean where organisms live on or near the ocean floor. What is this zone called?

• The ocean floor

• The surface of the ocean

• The middle layer of the ocean

• The area above the continental shelf

During a marine biology class, Maya asked which zone is located above the Benthic Zone?

• Epipelagic

• Bathypelagic

• Abyssal benthic

• Mesopelagic

During a marine biology class, Abigail was asked to describe the Bathyal Zone. What is it?

• The ocean floor from the continental shelf down to about 4000 meters.

• The ocean surface layer up to 200 meters.

• The deepest part of the ocean, below 6000 meters.

• The area between the high tide and low tide lines.

During a marine biology class, Arjun asked about the depth range of the Abyssal Zone. What is the depth range of the Abyssal Zone?

• 0-1,000 meters

• 1,000-2,000 meters

• 4,000-6,000 meters

• 6,000-10,000 meters

During a marine biology class, Benjamin asked, "What is the Hadal zone also known as?"

• Epipelagic zone

During a marine biology class, Samuel and Harper learned about a fascinating feature on the ocean floor. What is a hydrothermal vent?

• A place on the ocean floor where hot, chemical-filled water flows up through cracks in the Earth's crust.

• A type of underwater volcano that erupts lava.

• A deep-sea trench where tectonic plates meet.

• A coral reef formation found in shallow waters.
