(a) With the aid of diagrams, explain how the following factors affect the temperature of a place: (i) latitude (ii) aspect and slope
(ai)
- places that are nearer the Equator are warmer than places near the poles
- At the Equator, the sun is always high in the sky
- As such the sun shines vertically on the earth's surface
- therefore, heat is concentrated upon a smaller area which become hot
- Towards the poles the sun's rays fall at an oblique angle
- as such the rays have a greater area to heat; the sun's rays travel through a longer distance hence the intensity reduces
(aii)
-The influence of slope and aspect on temperature is noiceable in temperature latitudes
- in the tropics, the sun is always high in the sky to the aspect and slope of the do not affect temperature
- in the northern hemisphere, south facing slopes receive more insolation hence north facing slopes
- hence the south facing slopes are warmer
- north facing slopes are sheltered from the sun
- hence the north facing slopes are cooler
- in the southern hemisphere, north facing slopes recieve more insolation south facing slopes hence they are warmer
- on the contrary south facing slopes in southern hemisphere receive less insolation hence they are cooler
- the influence of slope on temperature is noticeable in mountanous area
- slopes facing the sun receive a lot more insolation than sheltered areas
- hence slopes facing the sun are warmer than sheltered slopes.
