Earth’s Waters Chapter 4.4 Pages 134-140Currents & Climate Earth’s Waters Chapter 4.4 Pages
Go With the Flow Currents: a large stream of moving water that flows through the ocean Carry water great distances Occur at varying depths
Surface Currents Surface currents affect water to a depth of several hundred meters Driven mainly by wind Move in circular pattern due to Coriolis Effect, caused by Earth’s rotation.
The Gulf Stream
Deep Currents Deep Currents are caused by differences in density, not wind Warm surface water flows to poles Cools and sinks Flows back towards equator.
Climate Climate is the pattern of temperature and precipitation typical of an area over a long period of time Currents affect climate by cooling / warming air above them.
Upwelling Upwelling is the upward movement of cold water from the deepCaused when wind pushes warm surface water away Deep water brings with it valuable nutrients.
Chapter 16 The Dynamic Ocean.
Crest- highest part of a wave Trough- lowest part of a wave Wavelength- horizontal length between crests. Wave height- vertical distance from crest to.
Vertical temperature change ● Temperature – there are 3 temperature zones in the ocean. ● Surface to 200 meters – warmed by the Sun. ● Thermocline: 200.
OCEAN CURRENTS AND WEATHER. Oceans currents are created by: surface wind, corliolis effect, land shape, and salt content and temperature of the water.
Movement of Air Chapter 14-4 Pages
Class 3b: Climate and Weather. Air pressure and winds Air is a fluid Warmer air is less dense Air moves from dense to less dense conditions Ex.: Land-sea.
Ocean Currents Objective:
Surface Currents (ocean) Affect water to a depth of several hundred meters Driven by winds Move in circular patterns in 5 major oceans. Because of Coriolis.
Ocean Currents “Rivers in the Ocean”. Currents Current – a large stream of moving water that flows through the ocean. Capable of moving large amounts.

Ocean Currents Chapter 16. Surface Currents A current is the flow of water moving through the ocean. Surface currents (flow in the upper 1000 m) are.
Surface Ocean Currents What are surface ocean currents? Ocean water that flows on the top layer of the ocean in predictable patterns around the Earth.
Unit 2.4: Currents and Tides. Vocabulary: 1.Current: a large stream of moving water that flows through oceans Unlike waves, currents carry water from.
Starter: What influences ocean currents? 10/23/ Convection and Ocean Currents 10/23/14 Practice : Glue notes here Application: Glue activity here.
Ocean Circulation Winds and Currents. The __________________ and the ___________________ interact The ocean and atmosphere transport heat from the ______________________________.
Ocean Motions Information to help you along in Earth science.
Ocean Currents 1.What is the cause of various kinds of oceans currents? 2.What is the impact of ocean currents on the transfer of energy around the globe?
Ocean Currents Text Book Page #
Ocean Currents. Objective Ocean currents are cause by unequal heating and differences in salinity. The currents distribute heat around the planet.
