What are the two type of
motions that we are
experiencing right now?
Rotation= Earth spinning on its axis
Revolution = the movement of one body
around another ( the earth revolves
around the sun in space)

Rotation
Earth spins 15o/hr on its axis
1040 mph at the Equator
800 mph at our latitude

Looking down on the Earth's North Pole, it is rotatingcounterclockwise.

Coriolis EffectNorthern hemisphere objects

RIGHT
Southern hemisphere objects deflect:
LEFT

Navigators must allow for deviation to right when flying in northern hemisphere -- and to left in southern hemisphere.
The rotation of the earth creates special problems on flights to and from the moon.

Fastest human = ~18 mph
Cheetah = 46 mph
Fastest car = 350 mph
Planes = up to 2,200 mph

FQ:
What causes the Coriolis Effect?
How does it affect the Northern Hemisphere?
