PPT-The Movement of Ocean Water

Chapter 14 Page 364 387 Currents Imagine that you are stranded on a desert island You stuff a distress message into a bottle amp throw it into the ocean hoping it will find its way to someone who will send help . While written to incorporate computer technology the lesson can be easily adapted to paper and pen Lesson Objective Students will compose a series of slides based on the exhibits at OC The teacher may select one type of exhibit such as those that co Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An . Ocean Current. is a large volume of water flowing in a certain direction.. Wind-driven currents are called surface currents.. Ocean Zones. Which Zone?. 1. Each . group. . will be given a set of words that relate to the different zones of the ocean.. 2. At your table you will . try and place . your words in the correct zone.. Actual Percentages. Water covers . 71% . of the Earth’s surface. The oceans contain . 97.25% . of all the water on Earth. 95% . of the ocean is still unexplored. 50% . of all know species are found in the oceans. What is a current?. 1. An Ocean Current . is a directed, continuous movement of ocean water generated by various forces.. 2. Currents are caused by various factors:. Temperature. Different salinity levels. MEDITERRANEAN SEA. NILE RIVER. CONGO RIVER. ZAMBEZI RIVER. NIGER RIVER. ATLAS MOUNTAINS. SAHARA DESERT. DRAKENSBURG MOUNTAINS. GREAT RIFT VALLEY. ETHIOPIAN HIGHLANDS. KALAHARI DESERT. MT.

We Do this both directly and indirectly. We eat fish that is harvested from the ocean. We also process harvested fish for livestock feed. . We get Valuable Minerals from the Ocean. Submersibles, satellites, and other technology allow scientists to study the structure and composition of the ocean floor.. a. system that uses transmitted and reflected sound waves to measure distances to the ocean floor; SONAR. EFFECT OF TEMP > EFFECT OF SALINITY. OCEAN LAYERS. SURFACE MIXED ZONE – less dense upper ocean, temp and salinity change often. TRANSITION ZONE – fairly constant density, acts as barrier between surface and deep zones. Section 2: Life in the Oceans. Section 3: Ocean Resources. Salinit. y. - measure of the mount of dissolved salts and other solids in a given liquid. Thermocline. - marks the distinct separation between the warm surface water and the deep, cold water.
