Slide 1 - Tekstslide
Energy Balance
Get your notebook or a piece of paper.
Slide 2 - Tekstslide
Slide 3 - Tekstslide
Coördinaten
Om een locatie te kunnen aanwijzen heb je twee getallen nodig: de breedtegraad en de lengtegraad (longitude.
Longitude
Latitude
Slide 4 - Tekstslide
Where is an energy surplus?
A
Low latitude
B
Middle latitude
C
High latitude
Slide 5 - Quizvraag
Is an energy surplus a positive or a negative thing?
Slide 6 - Tekstslide
Negative
Enhanced greenhouse effect
Positive
Renewable energy --> Solar Panels
Slide 7 - Tekstslide
What is the difference between an energy deficit and an energy surplus?
Slide 8 - Tekstslide
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 - Tekstslide
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
Slide 10 - Tekstslide
Slide 11 - Tekstslide
Slide 12 - Video
Slide 13 - Video
Slide 14 - Video
Temperatures above land and sea
Slide 15 - Tekstslide
Land gets warmer than water but it gets colder than water too.
Land heats up and cools down faster than water.
Slide 16 - Tekstslide
What effect does this have on for example the Netherlands?
Slide 17 - Tekstslide
In coastal areas, temperature differences are small.
(Flora and Fauna)
Slide 18 - Tekstslide
Pressure: High pressure & Low pressure
Slide 19 - Tekstslide
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 - Tekstslide
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 22 - Tekstslide
Slide 23 - Video
Global wind patterns
Slide 24 - Tekstslide
What is Buys Ballot's Law?
Slide 25 - Tekstslide
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).
