TEMPERATURE
FACTORS
  1. You can name the 6 temperature factors (G37).
  2. For each temperature factor you can explain how it influences temperature in a certain place (G38, G42, G43, G44, G45, G46).















Slide 4 - Diapositive

TEMPERATURE FACTORS
Why is it warm or cold somewhere?

Slide 5 - Diapositive

1. Latitude
The closer you are to the equator, the warmer it is.

Slide 6 - Diapositive

2. Altitude
The higher, the colder.

Slide 7 - Diapositive

3. Land or sea

  • Land heats up and cools down quicker than water.
  • Land and water influence the temperature of the air above it.


Slide 8 - Diapositive

4.Onshore/
offshore wind

  • This factor only applies to places close to the sea.
  • Onshore wind moderates temperature (cool summers, mild winters), while offshore winds cause bigger temperature differences.


Slide 9 - Diapositive

5. Ocean currents
Warm current -> warmer air
Cold current -> colder air

Slide 10 - Diapositive

6. Location of 
    mountain
    ranges
Mountain ranges can block prevailing winds, so they can be a dividing line between 2 climates.
