Only write down the question number and the answer. 1.1. F (1) 1.2. F (1) 1.3. T (1) 1.4. T (1) 1.5. F (1) (5) 2. Latitude or distance from equator Mountains or relief Ocean currents Altitude Distance from the sea (1x5=5) 3. Water is transparent so rays penetrate deeper (bigger area to heat) while only the top surface of land warms up. Water moves & distributes heat (waves and currents) Evaporation from water surface (uses energy) so cools the water down Water reflects much of the sun's energy (albedo) Land masses only need ½ as much eat to raise the temperature by 1°C as the same mass of water. ANY 3 (3x2 = 6) 4.1. The sun heats the earth’s surface in the form of short wave radiation called insolation. The earth then heats the atmosphere in the form of long wave radiation called terrestrial radiation. (6x1=6) 4.2. 1140m – 40m = 1100, 1100/100=11, 11 x 0.65˚C = 7.15 ˚C, 20 – 7.15 ˚C = 12.85 ˚C (4) (10) 1
