R27 Global and Local Winds1. What causes

wind?2. Why is the equator

hotter than the poles?

3. What is a convection current?

4. How many degrees latitude to get a wind belt?

5. Local Winds =

1. Uneven heating of the earth

2. Direct sunlight at the equator, angled sunlight spreads out the energy

3. Warm air rises and cold air sinks b/c differences in density and air pressure

4. 305. Convection currents that

affect a smaller area
