Earth is a rocky, inner planet with liquid water on over 70% of its surface.
Having two different types of surface (land and water) strongly affects the wind produced on Earth.
Which areas of the Earth receive more direct sunlight and therefore are hotter?
Surface type (land or water) and temperature (affected by direct/indirect light and hours of sunlight) can cause an uneven heating of Earth’s surface.
Warm air rises because it is less dense
Cold air sinks because it is more dense
Air near the poles will be colder and higher pressure.
Northern Hemisphere, it’s spinning is counter clockwise
Coriolis Effect on toilets?
All add together to create distinct wind patterns on Earth.
