What factors contribute to the temperature in a country?

Temperature factors

1. Latitude: the further from the equator, the colder.
   
2. Altitude: the higher, the colder.
   
3. Location in relation to the sea: the further from the sea, the warmer in summer and the colder in winter.
   
4. Supply of cold or heat from elsewhere by wind or sea currents.
   
5. Location of mountains: sheltered or not.

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).
   

TEMPERATURE FACTORS

Why is it warm or cold somewhere?

1. Latitude

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

2. Altitude

The higher, the colder.

3. Land or sea

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

3.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.

4. Ocean currents

Warm current -> warmer air

Cold current -> colder air

5. Location of 

    mountain

    ranges

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

What do you think is causing the drought in the atacama desert?

Arid conditions in Chile

Combination of three factors:

• High-pressure area
• Humboldt currents (ocean current)
  
• the Andes Mountains

Droogte in Chili
(Atacama woestijn)

Droogte komt door:

1. Subtropisch hogedrukgebied
2. Humboldtstroom (zeestroom)
   
3. Het andesgebergte
   

High-pressure area

1. high-pressure area

2. How is the arid/draught conditions near the atacama desert caused by the cold Humboldt seacurrent?

Humboldt current

3. Andesmountains

El Niño (het jongetje)

Opwarming zeewater door omgedraaide lucht- en zeestromen

Warmer zeewater:

Minder vissen

meer verdamping > meer neerslag, overstromingen etc>

Het Kerstkind

El Niño

- Verandering in lucht- en zeestromen (rond kerstmis).    - Gevolgen voor Chili: warmer zeewater, meer neerslag, overstromingen, minder visvangst.

Why doesn't the seawater off the coast of Chile evaporate.

1. The seawater is too warm so it does not evaporate
2. The seawater is too salty and does not evaporate
3. The seawater is too cold so it does not evaporate
4. The seawater belongs only to Spongebob

How many climates does Chile have?

4. 6

In a high-pressure area it does not rain because the air sinks. Why is that?

1. Rain only occurs when air becomes colder and descending air becomes warmer
2. Rain only falls when there is moisture in the air and valley air is dry
3. Rain only falls when there is a lot of wind and when the air is falling it does not blow
4. Rain only falls when there are clouds and descending air is too dry for tha

What is not a reason why the north of Chile is so dry?

1. The cold Humboldt current provides cold seawater
2. It is located on the leeward side of the Andes
3. High pressure causes air to descend
4. It's a desert. Duh
