2. Weather- is the combination of
temperature, humidity,
precipitation, wind, cloudiness,
and other atmospheric conditions
at a specific time.
Climate- is the characteristic
condition of the atmosphere near
the earth's surface at a certain
place on earth. It is the long-term
weather of that area (at least 30
years).

6. • The amount of solar energy varies markedly with
Latitude.
Variation Factors:
i. At higher latitudes, radiation hits the
surface at a greater angle, so it spreads over a
larger area.
ii. Radiation that intercepts the atmosphere at
an angle must travel through a deeper layer of air.

7.  As the winds move northward and
southward, they cool.
 In the horse latitudes (subtropical
high), where the cool air descends ,
two belts of dry climate encircle the
globe.
 The descending air warms and can
therefore hold more moisture.
 The dry air draws water from the
surface, causing arid conditions.

8. Fridge zones

9. Climate Polar region receive less intensive solar radiation because the sun's energy
arrives at an oblique angle, spreading over a larger area, and also travels a
longer distance through the Earth's atmosphere in which it may be absorbed,
scattered or reflected, which is the same thing that causes winters to be colder
than the rest of the year in temperate areas.
The axial tilt of the Earth has a major effect on climate of the polar regions.
Since the polar regions are the farthest from the equator, they receive the least
amount of sunlight and are therefore frigid. The large amount of ice and snow
also reflects a large part of what little sunlight the Polar regions receive,
contributing to the cold. Polar regions are characterized by the polar climate,
extremely cold temperatures, heavy glaciation wherever there is sufficient
precipitation to form permanent ice, and extreme variations in daylight hours,
with twenty-four hours of daylight in summer, and complete darkness at
mid-winter.

20. Clothing consisted of coat,
trousers, stockings, shoes or
boots.
This Inunait or Inuit parka/anorak is
typical of an Inuit woman's parka from
the early 1900s and was made from the
thin skins of summer caribou (the
summer skin is short, mostly consisting
of tight under wool). The parka has 2
extra layers to provide additional
warmth to its user.

22. WE CAN DIVIDED THE EARTH INTO 3
TEMPRATURE ZONES ACCORDING TO THE
SUN LIGHT RECEIVED ROUND THE YEAR
i. TROPICAL ZONE.
ii. TEMPERATE ZONE.
iii.FRIGID ZONE.

24. The region from23 1/2 North to
23 ½ south is known as
TROPICAL ZONE.

25. THE REGION BETWEEN 23 ½
NORTH TO 66 66 ½ NORTH AND 23
½ SOUTH TO 66 ½ SOUTH IS
KNOWN AS TEMPERATE ZONE.

26. THE REGION BETWEEN 66
½ NORTH TO 90 NORTH
AND 66 ½ SOUTH TO 90
SOUTH IS KNOWN AS
FRIGID ZONE.

28. Torrid zones

29. Torrid Zones
In the Torrid or tropical Zone, also known as the Tropics, the Sun is
directly overhead twice (only once at the extreme limits of the zone)
during the year.
In the Northern Hemisphere, after the sun moves north from the
equator it will be overhead once before it reaches, at the June
solstice, the Tropic of Cancer (at 23.5 degrees North), and
once after, before it moves south back to the Equator.
In the Southern Hemisphere, after the sun moves south
from the equator it will be overhead once before it
reaches, at theDecember solstice, the Tropic of
Capricorn (at 23.5 degrees South), and once after, before
it moves north back to the Equator.
The Torrid Zone is bounded by the Tropic of Cancer and
the Tropic of Capricorn.

32. A relatively rapid increase in
temperature has been documented
during the past century, both at
Earth’s surface and in the oceans.
 If emission rates for greenhouse
gases (which trap heat inside Earth’s
atmosphere) continue on their
current track, models indicate that
the globe will be 4.3 to 11.5°F
warmer by 2100 than it was in 1990.
