(a) What is an alluvial fan? (b) With the aid of a diagram, describe the characteristics and mode of formation of an alluvial fan.
Show the model answer
Model answer
(a) An alluvial fan is a fan-shaped deposit of sand, gravel and boulders laid down where a stream flows out of a steep mountain valley onto a flat plain. (b) Diagram: a mountain front, a stream leaving a narrow valley and a fan-shaped spread of deposits on the plain. Characteristics: fan or cone shaped; apex at the mouth of the valley; coarse material near the apex, finer towards the edge; streams divide into many channels; common in arid and semi-arid areas. Formation: a fast stream carries a heavy load down a steep slope; on reaching the gentle plain its gradient and speed drop suddenly; it deposits its load; channels become blocked and the stream shifts from side to side, spreading deposits in a fan; repeated deposition builds the fan up.
(a) Identify four factors which influence the amount of rainfall received in an area. (b) With the aid of a diagram, describe how latitude affects the temperature of a place.
Show the model answer
Model answer
(a) Latitude; distance from the sea; relief (windward or leeward side); prevailing winds and air masses; ocean currents; pressure belts (e.g. ITCZ); vegetation; altitude. (b) Diagram: globe with the sun's rays striking the equator vertically and the poles obliquely. In low latitudes the midday sun is high (overhead at some time of year), so its rays are concentrated on a small area and pass through a thin layer of atmosphere, giving high temperatures; towards the poles the rays are slanting, spread over a larger area and travel through more atmosphere, losing more heat, so temperatures are lower. Temperature therefore decreases from the equator to the poles.
