New Unit: Ocean Zones The student will know the five ocean zones and differences between them, and will explain how the oceans were explored and the features that were discovered.
Walk-In Copy the question and answer in sentences: How do you think scientists know facts about the ocean and its lifeforms?
Some Answers Scientists have dived below the ocean surface to observe and collect samples. Engineers have created vehicles that can go deep into the ocean to observe. Researchers at the shoreline have observed waves, shore life and weather.
What do we know about the oceans? Watch this video clip about the oceans, its mysteries and its lifeforms!
How do we know all this?!? The branch of science called…
Oceanography
Oceanography Branch of science that studies the ocean, its structures and the ocean floor.
Why Study Oceanography? Oceans comprise (make up) 71% of the Earth’s surface. Oceans can be a source of food. Oceans have a major effect on weather. They provide resources near the shoreline (food, plants, minerals).
Branches of Oceanography Oceanography has different branches that study the water, rocks at the bottom, wave movement, and life forms.
Study of rocks and sediments of the ocean floor. Geological: Study of rocks and sediments of the ocean floor.
- Ocean currents, waves, and effect on weather. Physical; - Ocean currents, waves, and effect on weather.
- Composition of sea water and chemicals in it.
- Study of life forms in the ocean and sea. Marine Biology - Study of life forms in the ocean and sea.
Design of ocean instruments and vehicles to explore the ocean. Ocean Engineering Design of ocean instruments and vehicles to explore the ocean.
