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 . 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.. By Ross . Nuechterlein. Convection. Convection.  is the movement of molecules within fluids and is one of the major modes of heat and mass transfer in liquids and gas.. Buoyancy . Buoyancy.  is an upward acting force exerted by a fluid , that opposes an object's weight.. s. Warm. . currents flow . away. from the . equator.. Cold. currents flow . toward. the . equator.. Ocean Currents. Sun. Wind. Coriolis. Effect. Gravity. Factors Influencing Currents. Energy from the Sun heats the water.. T. Lebrun. 1. , H. Massol. 1. , E. Chassefière. 1. , A. Davaille. 2. , E.

Identify the parts of a wave. . • Explain how the parts of a wave relate to wave movement. . • Describe how ocean waves form and move. . • Classify types of waves. . Oceans and Temperature. Ocean surface temperature strongly correlates with latitude because . insolation. , the amount of sunlight striking Earth’s surface, is directly related to latitude.. 1. Ocean currents carry warm water . Identify the parts of a wave. . • Explain how the parts of a wave relate to wave movement. . • Describe how ocean waves form and move. . • Classify types of waves. . Have you seen a wave? . We all know what ocean waves look like. Even if you’ve never been to the seashore, you’ve most likely seen waves on TV. . A puddle formed on grass after a heavy rainfall. But now the rain has stopped and the sun is out. In a few hours, the puddle will completely disappear. Design a model that uses arrows to show where the water in the puddle will go.. We Get Our Food from the Ocean. 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. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. Ocean Currents?. Chapter 9. First ….a key concept to keep in mind:. Winds. are named from the direction in which they are coming….. for example: A Southerly – is a wind coming from the south . 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. Develop and use models to explain the effect of the movement of ocean water (including waves, currents, and tides) on the ocean shore zone (including beaches, barrier islands, estuaries, and inlets)..
