Latitude & Energy
imaginary line that divides Earth into Northern & Southern hemispheres
EQUATOR
type of current moving from the South Pole
COOL
Ebergy transfers from warmer to ______ substances.
COOLER
Water heats and cools --- than land
MORE SLOWLY
large circular patterns of moving ocean water
GYRE
as latitude increases, the amount of solar energy transferred _______.
DECREASES
type of current moving from the equator
WARM
CAUSE: A warm current moves past a city.
EFFECT: _____
AIR TEMPERATURE INCREASES
Land heats and cools --- than water.
MORE QUICKLY
ocean currents move ---- around the globe
ENERGY
A city at 10oN will generally be ______ than a city at 60oS.
WARMER
warm currents transfer energy from ____ to ____
WATER TO AIR
CAUSE: A location is far from the equator.
EFFECT: ----
IT RECEIVES LESS SOLAR ENERGY/HAS LOWER AIR TEMPERATURE
Which city has a larger yearly temperature range?
Seattle (coastal) OR Minneapolis (inland)
MINNEAPOLIS
OBJECTS AND ORGANISMS
Why does latitude affect air temperature?
LATITUDE DETERMINES HOW MUCH SOLAR ENERGY IS TRANSFERRED TO THE SURFACE
A cold current moving past a coastal city will cause air temperature to ______.
DECREASE
Explain a chain of causes and effects that connects a cold current to cooler air temperatures.
COLD CURRENT -->WATER COLDER THAN AIR --> ENERGY TRANSFERS FROM AIR TO WATER --> AIR COOLS
Why does Seattle have more stable temperatures than Minneapolis?
THE OCEAN STORES AND SLOWLY RELEASES ENERGY
Why are ocean currents important for Earth’s climate system, even in places far from the equator?
THEY MOVE ENERGY FROM THE EQUATOR TO HIGHER LATITUDES, REDISTRIBUTING HEAT AND STABILIZING AIR TEMPURATURES AROUND THE GLOBE
Two cities are at the same latitude. One is much warmer than expected for that latitude. How this could happen?
A WARM OCEAN CURRENT TRANSFERS ENERGY FROM THE WATER TO THE AIR, INCREASING THE AIR TEMPERATURE.
If ocean water did not move, temperature would depend mostly on ____.
LATITUDE
Air temperature in a coastal city is higher than expected for its latitude.
Explain two different causes that contribute to this effect and describe how they are linked in a chain of causes and effects.
LATITUDE DETERMINES THE AMOUNT OF SOLAR ENERGY IS THAT IS TRANSFERRED TO THE SURFACE, AND A WARM OCEAN CURRENT CAN BRING WARMER WATER; ENERGY TRANSFERS FROM THE WARMER WATER TO THE COOLER AIR, THEREBY INCREASING THE AIR TEMPERATURE (MAKING IT WARMER).
The affect of ocean currents on coastal cities like Christchurch, NZ
MORE STABLE TEMPERAUTRES BECAUSE WATER STORES ENERGY WELL
How do ocean currents redistribute energy from the equator to other parts of Earth?
CURRENTS CARRY WARM WATER AWAY FROM THE EQUATOR AND MOVE COOLER WATER TOWARDS THE EQUATOR, TRANSFERRING ENERGY BETWEEN WATER AND AIR
