The horizontal motion of air relative to Earth's surface is
barometric pressure.
wind.
convection flow.
a result of equalized pressure across the surface.
Winds are named based on
the direction from which they originate.
the direction in which they are blowing.
the scientist who first described them.
the altitude at which they occur.
Which of the following is not a driving force of wind speed and direction?
electromagnetic force
pressure gradient force
Coriolis force
friction force
Which of the following is not true of the wind?
It is initiated by the pressure gradient force.

centrifugal force.
Which of the following describes the pressure gradient force?
It drives air from areas of higher to lower barometric pressure.

The El Niño-Southern Oscillation
is a periodic shift of high and low-pressure zones over the western and eastern Pacific, respectively, usually occurring every 2 to 12 years.
is a pattern of sea surface, air pressure, and wind shifts between the northern and tropical western Pacific.
is a north-south fluctuation of high and low-pressure zones in the North Atlantic Ocean.
has weakened throughout the 20th Century and is expected to disappear completely in the first couple of decades of the 21st century.
