| Wind Blow |
Wind is caused chiefly by the uneven heating of the earth by the
sun. All winds, from gentle breezes that rustle leaves to raging
hurricanes, are caused chiefly by the uneven heating of the earth by the sun.
When the air near the ground gets hot, it expands or
swells. This makes it lighter, and light
air rises.
As it rises, cooler, heavier air flows in to take its
place. This movement of air makes a
wind.
When the air moves slowly, we call it a breeze. When it moves fast and strong, we may call it
a gale or a hurricane.
If you live by the seashore, for instance, you may feel a cool
sea breeze on a warm day.
During the day, the land becomes warmer than the sea and so does
the air above it. As the warmer, lighter
land air rises, cool winds blow in from the sea to take its place.
All night the land cools more rapidly than the sea, and the
breeze is reversed. It blows out to sea.
What is true in your area is true on a larger scale of the big
winds that blow over the earth.
A wind gets its name from the direction it comes from. A north wind, for example, is one coming from
the North blowing toward the South. – Dick Rogers
