Question 1
- What do you understand by the term Climate.
- Briefly describe the relationship between Geography and Mathematics
Answer
- Climate is the average weather conditions of a given place for a long period of time, usually over 35 years
-
- Mathematics is a branch of science dealing with figures and numerical values.
- Formulae of mathematics are used to calculate distance and Area in Geography
- Numerical values in geography can be appropriately presented and analysed by means of mathematical techniques such as graphs and charts.
Question 2

- Identify the size of soil particle (i) and class of soil (ii)
- State three ways in which humus is important in the soil
Answer
-
-
- Gives soil a black or dark brown colour
- Source of nutrients to the plants
- Source of food for micro organisms in the soil such as Bacteria & fungi
Question 3
- What is the meaning of plate tectonics
- State three effects of convectional currents generated by the heat from the centre of the earth have on tectonic plates
Answer
- - The study of the movements of plates and various land forms resulting from such movements
-
- Causes plates to move away from each other
- Causes plates to move towards each other
- Causes plates to move parallel past one another along transform fault
Question 4
- Differentiate between an Earthquake and an Earth tremor.
- Identify three major regions where earthquakes are likely to occur?
Answer
- - An earthquake is a strong vibration of crustal rocks caused by seismic waves while an earth tremor is a mild vibration of crustal rocks
-
- Mid oceanic ridges
- Ocean deeps and volcanic islands
- Regions of crustal compressions
- Within the Rift Valley / faulted belts
Question 5
The feature below is formed from exoskeletons of polyps.
Describe the formation of the feature marked
Answer
- The feature marked S is a barrier reef formed by corals . Initially corals form close to the
shore and grow seaward level of the sea may subside forcing corals to grow further into the
steep sea. Later the level of the sea rises forcing the corals to grow upwards to catch up with the
phase of the rising level of the sea. Finaly a coral reef enclosed by a deep lagoon called a barrier
reef is formed, Alternative land may also subside or landslide is experience in the continental
shelf forcing corals to grow vertically upwards to catch up with the level of the sea forming a
Barrier reef
