PPT-Currents 13) Ocean currents can be caused by factors such as

wind salinity temperature the Coriolis Effect and gravitational pull 14Ocean currents flow in predictable patterns around the earth 15 Differences in density and temperature causes currents.

Describe. . the properties of ocean water.. Describe. . the two types of ocean currents.. Explain. how the ocean regulates Earth’s temperature.. Wind-driven surface currents. Figure 7-4. Ocean Circulation Animation. Ocean Currents. Ocean currents- are stream-like movements of water. Ocean currents affect our weather and climate. 2 Types:. 1) Surface Currents. Global winds. Ocean Currents . Local winds. Coriolis Effect. Because the Earth rotates, and consists of a mixture of land and sea, the . Coriolis Effect . exists. The . Coriolis Effect. is the movement of particles (such as air) to the right in the Northern Hemisphere. The water in the ocean moves in giant streams called currents.. Scientists place ocean currents into two major categories: surface currents and deep currents.. Surface . Currents. Ocean currents that occur at 328 feet deep or above. Transport . heat. Equator to poles. Transport nutrients and organisms. Influences weather and climate. Influences commerce. Surface . Currents. The upper 400 meters of the ocean (10%).. Deep Water Currents. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. How do different currents form. What is upwelling. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents. Currents only flow near the surface of the ocean. Warm Up & Spiral . November 4. How are surface currents created?. How are deep ocean currents created? . What are 2 factors that affect the density of water?. What is upwelling? . Objectioves. : 8.E.1.1/1.2. 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 . Ocean Current Layers. Surface Currents. . – . top . 10% of the ocean; upper 400 m. Deep Currents . – lower 90% of the ocean. Properties . of . Ocean . Water . How they impact ocean currents. Temperature. Chapter 14. Page 364 – 387. Currents. Imagine that you are stranded on a desert island. You stuff a distress message into a bottle & throw it into the ocean, hoping it will find its way to someone who will send help. .
