    • A.Waterfall✓ Correct Answer
    • B.Lake
    • C.Plain
    • D.Desert

    Explanation: Water streams dropping from a hanging valley create waterfalls.

    • C.Amazon
    • D.Ganga

    Explanation: The Congo River crosses the equator twice.

    • A.Limpopo✓ Correct Answer
    • B.Zambezi
    • C.Orange
    • D.Nile

    Explanation: The Limpopo River crosses the Tropic of Capricorn twice.

13. Q13.The process of soil being washed away by running water is:

    • A.Soil Erosion✓ Correct Answer
    • B.Soil Creep
    • C.Deposition
    • D.Weathering

    Explanation: This is water erosion.

14. Q14.Contour ploughing is a method to check:

    • A.Soil Erosion✓ Correct Answer
    • B.Flood
    • C.Drought
    • D.Earthquake

    Explanation: It slows down water runoff, reducing erosion.

15. Q15.Mulching helps in:

    • A.Retaining soil moisture✓ Correct Answer
    • B.Increasing erosion
    • C.Removing weeds
    • D.Drying soil

    Explanation: Covering soil (mulching) retains moisture and prevents erosion.

16. Q16.Shelter belts are used to:

    • A.Prevent wind erosion✓ Correct Answer
    • B.Stop floods
    • C.Irrigate fields
    • D.Grow fruits

    Explanation: Rows of trees (shelter belts) reduce wind speed and erosion.

17. Q17.The Nile River forms which type of delta?

    • A.Arcuate✓ Correct Answer
    • B.Bird's Foot
    • C.Estuarine
    • D.Cuspate

    Explanation: The Nile Delta is triangular/arcuate.
