Coördinaten
Om een locatie te kunnen aanwijzen heb je twee getallen nodig: de breedtegraad en de lengtegraad (longitude.
Longitude
Latitude
Slide 4 - Slide
Where is an energy surplus?
A
Low latitude
B
Middle latitude
C
High latitude
Slide 5 - Quiz
Is an energy surplus a positive or a negative thing?
Slide 6 - Slide
Negative
Enhanced greenhouse effect
Positive
Renewable energy --> Solar Panels
Slide 7 - Slide
What is the difference between an energy deficit and an energy surplus?
Slide 8 - Slide
Energy deficit (Low) Less energy than needed. More outgoing than incoming energy
Energy surplus (High)
More energy than needed.
More incoming than outgoing energy.
Slide 9 - Slide
Global warming
Global warming is caused by the enhanced greenhouse effect. The greenhouse gases reflects heat coming from the surface of the earth back towards the earth. This causes the atmosphere to increase in temperature

Temperatures above land and sea
Slide 15 - Slide
Land gets warmer than water but it gets colder than water too.
Land heats up and cools down faster than water.
Slide 16 - Slide
What effect does this have on for example the Netherlands?
Slide 17 - Slide
In coastal areas, temperature differences are small.
(Flora and Fauna)
Slide 18 - Slide
Pressure: High pressure & Low pressure
Slide 19 - Slide
Slide 20 - Video
High pressure area
Sinking air due to low temperatures.
Summer: Hot & Dry Winter: V Cold & Dry
+ / H / Maximum
Air molecules are close to eachother --> heavy --> sinking
Slide 21 - Slide
Low pressure area
Rising air due to high temperatures.
Summer: Hot & Rain Winter: Cold & Snow
- / L / Minimum
Air molecules are further away from eachother --> not as heavy --> rising

Slide 23 - Video
Global wind patterns
Slide 24 - Slide
What is Buys Ballot's Law?
Slide 25 - Slide
1. Air moves from H --> L
2. In the northern hemisphere the wind has a deviation to the right, in the southern hemisphere a deviation to the left (as if the wind is in your back when you're standing on the equator).
