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.
Oceans and Climate Changes
Crest- highest part of a wave Trough- lowest part of a wave Wavelength- horizontal length between crests. Wave height- vertical distance from crest to.
Guided Notes about Ocean Movements Chapter 15, Section 3.
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.
Boardworks Middle School Science Wind and Ocean Currents
Oceanic Circulation Current = a moving mass of water.
Ocean Currents and Climate
Grade Eight Science Chapter Two. An ocean current is a large mass of moving water in the ocean. A current moves in one, unchanging direction. There are.
Ocean Currents Objective:
CLIMATE WHAT IN FLUENCES the Climate of a region?
Surface Currents and Deep Currents
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.
