KNOWLEDGE

• You know that the Earth has a habitable climate thanks to the atmosphere.
• You understand the influence the position of the Sun and the geographical latitude have on temperature.

SKILLS

• You can calculate the average temperature.

The Earth has a blanket

1. Without the atmosphere, the temperature at night would be freezing cold / boiling hot.
2. The atmosphere is directly / indirectly warmed by the Sun.
3. The higher in the atmosphere, the higher / lower the temperature

The higher, the colder.

Temperature decreases on average by 6  ⁰C per kilometre.

The temperature at 1000 metres is 14 ⁰C.

What is the temperature at 2000 metres?


What is the temperature at 3500 metres?

The higher, the colder.

Temperature decreases on average by 6  ⁰C per kilometre.

The temperature at 1000 metres is 14 ⁰C.

What is the temperature at 2000 metres?
8 ⁰C

What is the temperature at 3500 metres?
-1 ⁰C

Average daily temperatures are used to describe the climate with.

• maximum temperature
• minimum temperature

5a + b. At what time of day is the temperature often the lowest? Explain your answer.

5c. When te maximum T is 21 degrees and the minimum T is 5 degrees. What is the average day temperature?

5d. What does the average day temperature say about the climate?

The Netherlands lies at 52⁰ N:

• Suns rays hit the Earth at an angle.

The Equator lies at 0⁰:

• Suns rays hit the Earth perpendicularly
• 3x as much Sun-energy as the poles

Because the Earth is a sphere, the angle of incidence of the Sun is different everywhere on Earth.

high Sun position

large surface is heated

4a. The photo was taken on the beach in the Netherlands. Is it evening or morning?
