![]() ![]() Ask students to take turns reading the Internet web pages and leading the discussion in their small groups. Encourage groups to use information from the diagram and the provided Internet resources, or classroom and library resources. Have students research the animals of each zone and their adaptations.ĭistribute the worksheet and have students work in small groups to complete it. Students should realize that it gets colder and darker and pressure increases as one moves from the surface to the bottom of the ocean.ģ. Have students predict the different conditions that exist in each habitat.Īsk students to describe the differences in pressure, temperature, and light in the different layers of the ocean. Ask: Why is the ocean divided into different zones? Elicit from students that each zone has unique characteristics and animal and plant life.Ģ. Explain that the abyssopelagic, or abyssal benthic, zone is the region that includes the ocean floor. Then point out to students that the top three zones together are called the pelagic zone, or open ocean. Point out the intertidal zone-in the epipelagic zone right above the continental shelf-and tell students it is the region along the shoreline covered by the sea at high tide but exposed to air at low tide. Point out to students that the deepest part of the ocean shown is 11,000 meters (36,100 feet), or approximately 11 kilometers (7 miles) deep. Discuss the significance of the depths shown on this diagram. The Abyssal Zone or the Abyssalpelagic zone is the next layer of the ocean that is approximately 13,000 ft below the oceans surface and reaches depths to 20,000 ft (4,000- 6,000 m).
