This week we have started our weather unit. We started by focusing on atmospheric circulation looking at the main reason we have weather: wind. We examined the atmospheric layers, understood the atmospheric circulation patterns and atmospheric pressure.
We watched a couple of videos:

This will help you understand why the globe experiences uneven heating, the circulation cells and why and how wind moves. We also checked out a weather map and how they work. See this video to help with understanding: https://www.youtube.com/watch?v=bd7DcVnrSL8

We read chapter 14, completed the chart on p. 237 and you should be able to answer #9 on p. 239.
On Thursday this week we focused in on the polar, ferrel and hadley cells and what climate we would match with these understanding the lows and highs that form as a result. (work sheet that is a hand in).
We also created three climate graphs and matched these with each of the cells above. Check out some examples of climate graphs on page 403 in Earth Matters.
Ensure the graphs are fully labelled.
Decide which climate graph represents a region under:
The Hadley Cell
The Ferrel Cell
The Polar Cell
Make sure you write an explanation as to why you made your choice.
Here are is the data for the three climate graphs:
