Troposphere
Which layer has the ozone
Stratosphere
What is the importance of the ozone
Absorbs UV rays-protects
Which layer contains charged molecules that glow
Thermosphere
What determines which organisms can survive in a region
Temp and precipitation
Why is it hotter at the equator
Sun rays are more concentrated and hits earth more directly. Travels shorter distance.
What is albedo
Percentage of incoming sunlight that is reflected from a surface
Warm vs cold air
warm air less dense
warm air more moisture
What factors determine which season it is
Earth tilt
Position around the sun
How do ocean currents affect local climate
Move water around and regulate temp
El nino
South American trade winds weaken

Why are air and ocean currents called heat engine systems
Air and water transport heat in currents
