3. Upland Regions Per 1000m temperature drops by how much?
What difference does height make to rainfall?
What difference does altitude make to sunshine hours?
Does more or less rain fall on the leeward side of a mountain?
Why are valleys often cooler than the hills that surround them?

4. Coastal Regions
Why does the wind often change direction on coastal areas?
Why does fog disappear by midday normally? (or soon after)

5. Forests Why don’t areas of woodland have high wind speeds?
Why are these areas cooler?
