1. Weather and Climate Year 11

2. You need to know… What is weather and climate? What causes rain (precipitation)? What are depressions and anti-cyclones? What weather do they bring? Case studies: a significant weather event a seasonal weather event

3. Weather and Climate Weather is the state of the atmosphere at any particular moment. Climate is the state of the atmosphere over a period of time. Weather can be measured Temperature (centigrade) Pressure (millibars) Rainfall (millimetres) Wind direction Wind speed (mph) Cloud cover Climate can be measured Months Rainfall Temperature

9. Map and source evidence Use evidence from maps and graphs to answer questions on industrial location and change Question B4 c, d (Paper 2, June ‘04) BUG Box the question word, Underline the key words and Glance back to check you’ve understood what the question is asking.

10. (c)(i)1 mark for distance; 1 for direction ref. (1+1) = [2] Examples: About 28oN (1) of the Equator (1) About 400 km (1) east of China (1) About 600 km (1) north-east of Taiwan (1). (ii)Three points required. (3x1) = [3] Example: From 2nd August moved north (1) 400 km (1) east of China (1) and 350/400km (1) west of Japan (1) eventually reaching land on the west coast of South Korea (1) (d)(i) No mark for country; 2 marks for reasons. 1 max for description. Example: China because highest number of dead at 400 (1) and highest number homeless at 1.8m (1). (1+1) = [2] (ii) Looking for at least two different responses; credit 4 max for one well-qualified answer. Examples: Most LEDCs are economically poor (1) so lack technology/investment in severe weather warnings (1) and regard warnings as low investment priority/take the risk (1). Lack of organised emergency procedures (1) means vulnerable to maximum exposure to damage (1). Many LEDCs are situated in areas where severe weather events occur (1) so they get most damage (1). Housing/infrastructure of LEDCs of poor quality (1) with low safety standards (1) and often weak shelters of poor materials (1). Communications in LEDCs are poor (1) so difficult to spread any warning messages in time (1). Population usually high in LEDCs (1) and not mobile enough due to poor/lack of transport to evacuate quickly (1). Medical care is low in LEDCs (1) so great loss of life following the event.
