3 tto part II

• Aardrijkskunde
• Middelbare school
• havo, vwo
• Leerjaar 3

First 10 minutes: Work on your own!

- Read section 3.1 and read your notes from last time!

- Unfortunately don't have the test results, but before the end of the lesson you might have! You will correct your own test :D

- I need to do something important, I will tell you later

- Ten minutes later we will continue!

Planning:

• Reading and answering questions
• Recap last time
• El Nino

Lesson goals

• which factors influence the climate
  
• What is el Nino and what are the differences between el Nino situation and the normal situation?

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

How many climates does Chile have?

1. 3
2. 4
3. 5
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

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.

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

Humboldt current

3. Andesmountains

EL NIÑO

Climatic phenomenon that heats sea water

in the central and eastern Pacific.

Once every three to seven years, el Niño lasts about six months and the peak is often around Christmas.

5. Ocean currents

Warm current -> warmer air

Cold current -> colder air

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.
