Ocean Currents
What are the 2 types of ocean currents?
Deep and Surface
What causes wind on earth
Differences in air pressure
How does water from the ground make its way into the clouds
evaporation
What do you call the movement of air or water in a stream
current
Due to the Coriolis effect winds in the N Hemisphere turn ____________ while winds in the S Hemisphere turn ___________
Clockwise, counterclockwise
What 2 things effect deep ocean currents
Salinity, Temperature
Describe a convection current
warm air rises cold air falls causing movement
What do we call the process where water cools off in the clouds and becomes liquid again?
condensation
explain the difference between high pressure fronts and low pressure fronts
High pressure means cold air low pressure means warm air
What energy source caused currents in the air and water
Sun
What 3 things effect surface currents
Continental deflections, global winds, and Coriolis effect
Why does cool air always sink
Its more dense
rain snow and hail are all examples of what
precipitation
Global wind belts located near the equator
Trade winds
Warm currents typically bring what type of weather
warm, wet
What warm ocean current brings warm weather to the southern united states
gulf stream
Explain a land breeze
cool air over the land replaces warm air over the ocean
explain all steps of the water cycle
water evaporates, it condensates in the clouds and falls in the form of precipitation
Calm area near the equator with no wind is called what
Doldrums
What causes the Coriolis effect
earths rotation
Whare do most warm and cold ocean currents originate from
cold/poles warm/equator
Explain a sea breeze
cool air over the ocean replaces warm air over the land
What do you call water that is released by plants into the air?
Transpiration
explain the Coriolis effect
earths rotation causes currents to appear to move in circles
What effects do currents have on coastal areas
they effect the weather by warming and cooling the air
