What is the intertidal zone?

• The area between the high and low tide lines

• The deepest part of the ocean

• The area where rivers meet the sea

• The zone with the most coral reefs

What is an ocean trench?

• A shallow area in the ocean

• A deep valley in the ocean floor that forms along a subduction zone

• A flat area on the ocean floor

• A mountain range under the sea

Where are hydrothermal vents located?

• On the ocean surface

• On the ocean floor where hot gases and minerals escape from Earth's interior into the water

• In the middle of the ocean

• Near the coastline

What is the photic zone?

• The deepest part of the ocean

• Portion of the marine biome that is shallow enough for sunlight to penetrate

• A dark area of the ocean where no light reaches

• The area where ocean currents are strongest

What is upwelling?

• The movement of warm, nutrient-poor water to the surface

• The movement of deep, cold, and nutrient-rich water to the surface

• The sinking of surface water to the ocean floor

Which of the following best describes the function of phytoplankton in aquatic ecosystems?

• They are predators of small fish

• They are decomposers breaking down organic matter
