-You understand the influence the position of the Sun and the geographical latitude have on temperature.

-You can calculate the average temperature.

What fits best with weather and what with climate. Swipe please

Climate

Weather

measured over 30 years

Can change any minute

big area

small area

high latitude

Low latitude

Why is snow more common in Switserland than in the Netherlands? 

Why is snow more common in Finland than in the Netherlands?

Why is snow in Poland more common than in the Netherlands? 

Which termperature factor plays a role here?

altitude

Latitude

distance to the sea

Low latitude

high latitude

It is colder at higher latitudes because:

• -Sunrays hit earth at a slanting angle (vallen schuin in)
• Sunrays have to heat up a larger area
• Sunrays travel a longer distance to earth which gives them a higher change of being reflected back to space

please note!

The further from the equator, the colder

Language to use

I think the …. could be ..

You reckon it is… …?

Which of them shows….?

What do/does the …. mean?

• Air in the atmosphere is heated from below
• the higher you go, the further you are from the earths surface

Altitude

Altitude

The higher you go, the colder it gets

Altitude

Rotations of the earth

earth has two rotations

in 24 hours: a spin around its own axis> day and night

in 1 year: a spin around the sun> seasons

please note!

What creates the difference between night and day?

1. rotation of the earth around the sun
2. rotation of the sun around the earth
3. the moon and its gravity
4. the earth rotating around its own axis

Which month gives the Netherlands the most daylight?

1. Maart
2. Juni
3. September
4. December

Why do we have less daylight in the winter?

minimum and maximum temperature

Every day has a maximum temperature.The warmest moment of the day. This is somewhere between 12:00 and 15:00 depending where you are. 

Everyday also has a minimum, when it is coldest. This is usually somewhere just before morning

Why is the coldest moment of the 24hour cycle just before sunrise?

The atmosphere gets heated from

1. Below
2. Above

How many degrees does the temperature drop if you climb a 1000meters?

1. 10 degrees
2. 1 degree
3. 6 degrees
4. 3 degrees

Explain why it is colder in the Netherlands than on the equator. Use at least 4 sentences
