GEOGRAPHY TOPICAL QUESTIONS AND ANSWERS

It is a condition where the incoming solar radiation passes through the atmosphere while the outgoing terrestrial is blocked by the gases/ atmosphere making the earth retain most of the terrestrial radiation. This makes the earh to be warmer than it would have been or it is a condition where the atmosphere balances the incoming and out-going and out-going terrestrial radiation making the earth to retain optimum heat.

KCSE Geography Paper 1 1998 Section B Question 8.

The graph below represents the climate of a station in Africa. Use it to answer question

(i) Describe the characteristics of the climate represented by the graph

Temperature are higher between September and March/ relatively low during April to August
Most of the rainfall is received during the warmer season/ cool season relatively dry/ single maximum R/F regime
The highest temperature are experienced in December (230C) / the lowest temperature range is large / 140 C
The highest rainfall is received in December (125mm) the lowest June to August ( 10mm)
There is no distinct dry month
Rainfall is low ( 6.55mm)

(ii) Describe the type of natural vegetation likely to be found in an area with the type of climate represented by the graph.

(iii) Scrub/ thicket/bush/ Shrubs

Grass is tall in the wetter areas and short in drier areas
The vegetation in mainly grass
Trees are only found along water courses/ trees scattered
Grass withers during the dry season/ winter but spouts at the beginning of wet season
Acacias
Umbrella shaped trees/ thorny trees

(b) Explain four factors that influence climate.

Latitude
Areas near the equator are hotter than those far away from the equator. This is due to a higher concentration of trees in rays per unit area at the equator. The amount of solar insulation decreases polewards since it passes through a longer distance of the atmosphere and therefore more interference.
Altitude
Lowlands are usually warmer than highlands because the atmosphere becomes thinner as the altitude increases where the ground loses heat to enter space faster. Atmosphere pressure decreases with increasing altitude. This is due to the weight of atmospheric air above highlands being less than in lowlands.
Distance from the sea/ continentally
During the hot season, coastal lands are relatively hotter than inland areas on the same latitude due to the existing effect of the sea breezes. By the time the sea breezes. By the time the sea breezes reach inland areas they have adapted to the temperature of the land for which are passing. During the cold season the effects is reversed.
Ocean currents
When winds are on shore warm ocean currents have a warming effect on the adjacent coasts./ Lead to higher rainfall than inland areas/ cool ocean currents have a cooling effects/ drying effect on the adjacent coastlands.
Wind/Air Masses
Warm/ cool winds bring a warming/ cooling influences to a place if they come from a warm / cool zone. Areas under the influence of dry winds have little or no rainfall/ areas under moist winds are usually wet.
Aspect
In the northern hemisphere outside the tropics the non facing slopes are cooler than the south- facing slopes because they do not receive direct solar isolation. (The reverse is true for the southern hemisphere). Windward slopes are generally wetter than leeward slopes because the moisture- laden winds rise and drop their moisture on this side first.

Maximum and minimum thermometer

Used to record/ measure maximum and minimum temperature in a day
Be at the station at the convectional time for taking records
Read the position of the metal indices for both maximum and minimum temperature
Record the readings in a book or table
Reset the thermometer using a magnet (3mks)

(iii) State three advantages of studying the weather through
fieldwork

It enables students collects first hand information
Students develop skills of weather observation

a) Differentiate between weather and climate (2 mks)

Weather is the atmospheric conditions of a place over a short period of time, usually twenty- four hours , whereas climate is the average weather conditions of a given place over along period of time, usually 30-35 yrs.

The graph below shows climatic characteristics of a station in Kenya. Use it to answer the following questions

i) Calculate the annual range temperature. (1mk)

The annual range of temperature is 15⁰C

ii) Calculate the total amount of rainfall received at the station (1mk)

Total amount of rainfall is 1300mm
