   River regime is best described as the

   1. A
      Channel shape and river cross-section
   2. B
      Pattern of river discharge throughout the year
      Correct
   3. C

   4. D
      Speed of water flow in the river
   Show answerHide answer

   Answer: B

   The pattern of river discharge throughout the year option correctly describes river regime. Regime shows seasonal variation in water flow and is influenced by climate and drainage basin characteristics.

4. 4.

   An example of a coastline of emergence is

   1. A
      The Dalmatian coast with rocky islands
      Correct
   2. B
      The Norwegian fjord coast
   3. C

5. 5.

   "An open forest with evergreen, thick leathery leaves and woody stems with deep roots" is known as

   1. A
      Coniferous forest
   2. B
      Savanna woodland
      Correct
   3. C
      Deciduous forest
   4. D
      Equatorial rainforest
   Show answerHide answer

   Answer: B

6. 6.

   The coastal regions of Sierra Leone record an annual rainfall of over

   1. A
      2000mm
   2. B
      3000mm

      1000mm
   4. D
      4000mm
      Correct
   Show answerHide answer

   Answer: D

   The over 4000mm option is correct. Sierra Leone's coastal regions receive over 4000mm of annual rainfall, making them one of the wettest areas in West Africa due to monsoon influence.

7. 7.

   The difference in time between two longitudes is approximately

   1. A
      2 minutes per degree
   2. B
      4 minutes per degree
      Correct
   3. C
      6 minutes per degree
   4. D
      10 minutes per degree
   Show answerHide answer

   Answer: B

   The 4 minutes per degree option is correct. Since Earth rotates 360° in 24 hours (1440 minutes), each degree of longitude represents 1440÷360 = 4 minutes of time difference.

8. 8.

   Plateaux formed together with fold mountains are best described as

   1. A
      Erosion plateaux
   2. B
      Volcanic plateaux
   3. C
      Inter-mountain plateaux
      Correct
   4. D
      Block mountains
   Show answerHide answer

   Answer: C

   The inter-mountain plateaux option correctly describes plateaux formed alongside fold mountains. These elevated plains lie between ranges of folded mountains.

9. 9.

   Soil erosion by action of rain can be caused by all of the following except

   1. A
      Absence of vegetation cover
   2. B
      Use of mulch and cover crops
      Correct
   3. C
      Steep slopes
   4. D
      Heavy rainfall intensity

       The changing position of stars throughout the year
    4. D
       The presence of different climate zones
    Show answerHide answer

    Answer: A

    The curvature of Earth visible from space and ship disappearance option is the most direct evidence of Earth's sphericity. The perspective change as objects move away demonstrates Earth's curved surface.
