Geography - Storms

Niamh started on the year 6 Bitesize which she had no issues with and completed the little test.

Niamh then had some questions which were more complicated so some further research took place.

One of Niamh's questions was 'why is it colder at the top of a mountain when it's closer to the sun?

We went onto another webpage to learn about air pressure and this has been copied and pasted from that, it explains it far better than I could but Niamh understood this due to watching a film about Everest climbers also. 

You may already know about the relationship between temperature and pressure: When you pressurize air (or any gas), it gets hotter, and when you release the pressure on air it gets colder. So a bicycle pump gets hot when you pump up a tire, and a spray paint can or a C0₂ cartridge gets cold as you release the pressurized gas. A refrigerator puts both of these processes together, pressurizing gas on the outside of the refrigerator to release heat and decompressing it inside the refrigerator to absorb heat (see How Refrigerators Work for details).

You may also know that air pressure decreases as altitude increases.
