1. LOCAL WINDS Land and Sea Breezes At night the reverse takes place.
The land surface is heated more intensely during the daylight hours than an adjacent body of water is heated.
As a result, the air above the land surface heats,
expands, and rises, creating an area of lower pressure.
At night the reverse takes place.

3. GLOBAL WINDS Air heats up at the equator and rises.
It moves towards the poles and cools down and sinks.
This creates convection currents that we call global winds.

5. Coriolis Effect
The Coriolis effect describes how Earth’s rotation affects moving objects.
In the Northern Hemisphere, all free-moving objects or fluids, including the wind, are deflected to the right of their path of motion.
In the Southern Hemisphere, they are deflected to the left.

7. Review
Tell whether the following are examples of conduction, convection or radiation:
The heat from a furnace heating the room.
You put a spoon in hot chocolate and it gets hot
The heat from the sun warms the earth.
Cold water in the ocean sinks, causing currents.
You feel the heat of hot pavement through the bottoms of your flip flops.
