Main source of energy for Earth
The Sun
Land and water heat the air through what process
direct contact - conduction
Large scale water movements
currents
Convection is
The circular motion formed by warm and cool fluids
What causes wind?
Uneven heating of the earth's surface by the sun.
The way energy travels to Earth from the Sun
Radiation
How does atmospheric circulation influence climate?
Redistributes heat and moisture
What is another name for oceanic circulation?
Thermohaline circulation
warm air or water will ______________ and cool air or water will ___________
warm = rise
cool = sink
What are the 3 Global winds called?
Trade winds,Prevailing Westerlies,and the Polar Easterlies
Reason you feel warmer in a black t-shirt on a sunny day than a white one
Dark colors absorb heat better - lower albedo
White reflects better - higher albedo
What controls atmospheric circulation?
Temperature differences
Surface currents are formed by the ___________ and shaped by the _______________
formed by wind blowing the top layer of water away
Shaped by the Coriolis effect
warm
This causes winds and water to curve
Coriolis Effect
Which has a higher specific heat sand or water and why
Each hemisphere is broken into how many convection cells
Daily double - can you name them
3 cells Hadley cell,Ferrel cell,Polar cell
Besides temperature, this influences the density of ocean water
salinity
This system of surface and density currents helps distribute heat across the globe through water. What is it called
Global (Great) Conveyor Belt
This wind belt blows over the continental United States What is it called and which way does it blow
Westerlies blow from west to east
Reasons Earth has unequal heating
1. Different latitudes get different amounts of solar radiation
2. Different surfaces absorb heat at different rates based on their specific heat and albedo
Air flows from
Areas of high pressure to low
4 things that affect ocean currents (Hint: Density is not one of the answers I'm looking for, break it into its pieces)
wind, temperature, salinity, and landmasses
Cool air rushes in to replace rising warm air. This is called ___________
In the ocean cold water rising up to replace surface water is called _______________
air = wind
ocean = upwhelling
This is the reason a sea breeze blows during the day and a land breeze at night.
Land heats and cools faster than the water
