Slide 1 - Slide

Energy Balance
Get your notebook or a piece of paper.

Slide 2 - Slide

Slide 3 - Slide

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 22 - Slide

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).
