2 Lesson #2 Ocean Floor Vocabulary Answers 1. Continental shelf: it extends in a gentle downward slope from the shorelines of the continents into the oceans. It covers about 5% of Earth s surface. 2. Continental edge: is the point at which the shelf surrounding each continent begins to angel sharply downward toward the ocean depths. 3. Continental slope: is the cliff-like drop beyond the continental edge 4. Continental rise: stretches from the lower portion of the continent slop to the deepest part of the ocean 5. Abyssal plain: the bottom of the ocean that covers about 46% of Earth s surface. Parts are flat, but others have deep canyons called trenches. 6. Mid-ocean ridge: the chain of underwater mountains. It is the longest mountain range in the world, passing through the Atlantic, Indian, and Pacific Oceans. 7. Seamounts: are free-standing mountains formed by volcanoes. These seamounts have been flattened because of wave action.

6 Lesson #4: Life in the Ocean Notes Teacher Copy - Today more than 200,000 species of plants and animals live in the ocean. - These organisms can be divided into three groups according to the depth at which they live: 4. Plankton: a. Includes organisms that float on or near the surface and drift with the ocean currents b. There are two types of plankton: phytoplankton and zooplankton. c. Phytoplankton are too small to see with a microscope. d. Phytoplankton produce 80% of oxygen through photsynthesis. e. Zooplankton include larval forms of ocean creatures. When they mature, the adult organism will no longer be considered plankton. f. Examples of zooplankton are :lobsters, jellyfish, and corals. 5. Nekton: a. Consists of all creatures that swim including invertebrates such as squids and octopuses, all kinds of fish, and mammals such as whales. b. Nekton can live at any depth, from the surface to the ocean floor. c. Most creatures stay where the water pressure and other conditions are suitable for their needs. 6. Benthos: a. Consists of plants and animals that live on the ocean floor and do not swim. b. The ocean floor starts at the shoreline and goes to the deepest parts of the ocean. c. Most members of this group live in shallow water, where food is plentiful and water is warmer. - All food chains in the ocean start with phytoplankton. - All creatures need phytoplankton for the oxygen they produce.

Students are encouraged to use this site as well in finding information about their ocean animal This movie clip from National Geographic is an overview of the ocean. It talks about water in the ocean, life found in the ocean, and other areas of oceanography. The movie clip will be playing at the end of the unit, on the last lesson as a wrap-up of the unit.
