1. Latitude G33/34
2. Altitude G84
3. Distribution of land and sea G36-39
Latitude
• How far away is a place
from the equator?
• Definition: the distance
in degrees of a place
from the equator
• Places with a low latitude
have a higher temperature
than places with a high
latitude
Latitude and temperature
 When the sun shines vertically the heat is more
intense, because it has to warm a small surface.
 When the sun shines diagonally, the heat is less
intense, because the heat is diverted over a
bigger surface.
diagonally high latitude
vertically
low latitude
Angle of the sun
• The more diagonally the angle of the sun,
the bigger the part that has to be warmed
up.
Altitude
• Places on a higher
altitude are colder than
places on a lower
altitude.
• Air is warmed up from
the earth.
• When you go 1000
metres up, the
temperature goes 6˚C
down.
Distribution of land and sea
• Land warms up quickly and cools down
quickly; water warms up slowly and
cools down slowly.
Direction of the wind
• Onshore winds: come from the sea and give a
temperature moderation.
• offshore winds: come from the land and give
very high (summer) or very low (winter)
temperatures.
Ocean currents
• In the oceans there are warm and cold
gulf streams, which make the temperature
on land go up or go down.
Location of the mountains
• A mountain range can stop (moisture) air
and therefore cause a different climate on
each side of the mountain range.
• For example the Himalaya mountain
range: on the southside the climate is very
warm and moisture. The north side on the
other hand is very dry and a lot cooler.
