Learning goals 3.2
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.

Slide 7 - Slide

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

Slide 8 - Slide

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?

Slide 9 - Slide

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

Slide 10 - Slide

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?

Slide 12 - Video

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.
