KCSE Geography Paper 1 2011 Section B Question 7.

(a) (i) State three conditions that are necessary for siting a weather station.

• The area should be away from buildings/trees/tall objects.
• The ground should be free from flooding.

(b) The table below shows the temperature and rainfall figures for a weather station in Kenya. Use it to answer question (b) and (c).

​Calculate:
(i) The mean annual temperature for the station. 

(ii) The annual range of temperature for the station.

• (i) The mean - 16.1°C
• (ii) Annual range of temperature - 2.1°C

​(c) (i) On the graph paper provided, draw a bar graph to represent the rainfall figures for the station. Use a vertical scale of 1cm to represent 20mm. 

​(ii) Describe the characteristics of the climate experienced at the weather station.

• The climate conditions are generally cool.
• The station receives high rainfall/2125mm.
• The lowest rainfall (71 mm) is received in December /the highest rainfall (323 mm) is received in May.
• The temperature ranges from 15.0° in August to 17.1°C in March/April. /The annual range of temperature is small /(2.1 °C).
• The area is wet receives rainfall throughout the year.
  
• There is no dry month.

​(d) Suppose you visited a weather station for a field study on weather;
(i) Give three methods you would use to collect data.

• Observation
•  Interviewing
•  Reading from secondary sources
•  Administering/filling in questionnaire s
•  Taking measurements e.g. rainfall
•  Reading instruments (Thermometer)
•  Filming/video taping/taking photographs.

​(ii) State three advantages of studying weather through fieldwork.

• It enables students to collect first hand information.
• It helps students to develop manipulative skills.
• It enables students to learn how to make weather recording instruments.
• It enables students to apply the knowledge learned in the classroom.
• It makes learning interesting.
• It makes learning real
• It provides detailed/in-depth/broader learning.
