Start-Up excercise 

Have you ever traveled to a place with a very different climate from the Netherlands? Discuss with your neighbour what the difference was

§ 3.1: climates around the world

Learning targets

-You know which climates there are on Earth.

-You understand what influence the latitude has on climates.

-You can explain why vegetation differs between climates.

What is 'weather'?

What is climate?

Which 3 elements make up weather?

1. Wind, Sun, Snow
2. Precipitation, Wind, Temperature
3. Temperature, Rain, Wind
4. Wind, Sun, Precipitation

Weather

The condition of the atmosphere at a specific time and at a specific place. 

Climate

The average weather measured over a period of thirty years. 

climates on earth

Tropical rainforest

- Always above 18 degrees

- Lots of precipitation (average 2000 mm a year)

- Close to the equator (low latitude)

- There are no seasons (spring, summer, autumn, winter)

- Lots of vegetation (plantgrowth)

Veel plantengroei, dit komt door de hoeveelheid neerslag die er valt.

Savanna climate

- Dry and wet season 

- Less precipitaion:  1000-1500mm per jaar

- Vegetation: grasses and some trees 

- Wildlife: Zebras, Lions etc

- Low latitude

Veel dieren, omdat het er genoeg geregend en de temperatuur altijd hoog is.

Steppe climate

- Vegetation: some grasses or bushes, no trees

- little precipitation: 200-500mm a year

- Low latitude

Climate with high temperatures and little precipitation that

limits vegetation to grass. 

Desert Climate

- Little precipitation (less than 200mm a year) 

- Almost no vegetation

- Low latitude

Climate with usually high temperatures and nearly no

precipitation. 

Savanna climate

Steppe climate

Tropical climate

Desert climate

Low latitude/high latitude

• Low latitude means close to the equator
• High latitude means close to the poles
• Why?

Low latitude

low latitude

high latitude

high latitude

Start-up exercise. Name a few climatezones

Latitudes

Temperate sea climate 

- Average because it is not too cold or warm, not too dry or wet. 

- this is due to the sea

- High latitude

Continental climate

• Warm summers, cold winters
• Example: Russia
• High latitude

Tundra climate

• It is always cold here, trees can no longer grow
• High latitude

Het is hier erg koud, waardoor er geen bomen groeien.

Why does the continental climate only exist on the northern hemisphere?

Polar climate 

• Can be found where it is close to freezing point all year around
• at high latitude 
• or in high mountain ranges
