•Brazil has a large area where
the average wind speed is
low.
•Gabon, Congo and DR Congo
in Africa, Sumatra, Indonesia
and Malaysia are the least
windy places on earth.
Seasonal winds are those
which change their
direction according to
season in a year.
• They are called as

• These winds blow from
sea to land during summer
and land to sea during
winter.
The horizontal movement of air is called
wind.
• Vertical movement of air is said as air
current.
• The winds move from high pressure to low
pressure.
• Unlike other elements a wind is made up
of a series of gusts and eddies which can
only be felt and not seen.
• Winds get their name from the direction
from which they blow i.e, wind blows from

the availability of oxygen to
breath also decreases.
• At very high altitudes,
atmospheric pressure and
available oxygen get so low
that people can become sick
and even die.
