2. Main Ideas
1.Warm air rises.
2.Air moves toward the place
where warm air is rising.
3.Air moves from high-pressure
areas to low-pressure areas.
4.Land heats up (and cools
down) faster than water.
4. What happens to the air in the
surroundings as warm air
rises?
5.
6. Warm air is rising
Air moves toward
the place where
warm air is rising
7. What makes the air move?
When the sun heats up the earth, some places
heat faster than the others. The air above the
warmer places will also warm up and will rise
as a result. The air in the surroundings will
then move toward the place where warm air
is rising. We call this moving air as wind.

22. Low Pressure
A low-pressure
area, low or depression, is a region
where the atmospheric pressure is
lower than that of surrounding
locations. The formation process of a
low-pressure area is known
as cyclogenesis. Lows are usually
associated with high winds, warm air,
and atmospheric lifting. Because of
this, lows normally produce clouds,
precipitation, and other bad weather
such as tropical storms and cyclones.
23. HIGH PRESSURE SYSTEM
"high," is an area where the
atmospheric pressure is greater than
that of the surrounding area. In some
places highs are referred to as
anticyclones. These move clockwise in
the northern hemisphere and
counterclockwise in the southern due
to theCoriolis Effect.
