Practice Questions from Geography Chapter 11 Movements of Ocean Water with Stepwise Answers

1. Multiple choice questions.

Q1. The upward and downward movement of ocean water is known as:

(a) tide
(b) current
(c) wave
(d) none of the above

Answer: (a) tide.

Tides refer to the periodic rise and fall of sea level mainly due to the attraction of the sun and the moon.

Q2. Spring tides are caused:

(a) As result of the moon and the sun pulling the earth gravitationally in the same direction.
(b) As result of the moon and the sun pulling the earth gravitationally in the opposite direction.
(c) Indention in the coast line.
(d) None of the above.

Answer: (a) As result of the moon and the sun pulling the earth gravitationally in the same direction.

This causes higher high tides known as spring tides.

Q3. The distance between the earth and the moon is minimum when the moon is in:

(a) Aphelion
(b) Perigee
(c) Perihelion
(d) Apogee

Answer: (b) Perigee.

Perigee is the point where the moon is closest to Earth.

Q4. The earth reaches its perihelion in:

(a) October
(b) September
(c) July
(d) January

Answer: (d) January.

Earth is closest to the Sun (perihelion) around 3rd January each year.

2. Very Short Answer (VSA).

Q5. What are waves?

Answer: Waves are the oscillatory movements on the ocean surface, where only energy is transferred while the water particles largely move in small circles.

Q6. Where do waves in the ocean get their energy from?

Answer: Most ocean waves get their energy from wind blowing against the surface of the water, transferring energy to the water body.

Q7. Define tides.

Answer: Tides are the periodical rise and fall of sea level, occurring once or twice daily, mainly due to gravitational attraction of the sun and the moon.

Q8. What causes tides?

Answer: Tides are caused primarily by the gravitational pull of the moon and, to a lesser extent, the sun on the Earth’s oceans, along with centrifugal force.

Q9. How are tides linked to navigation?

Answer: Knowledge of tides helps navigators plan safe entry and exit for ships, especially in shallow harbours, enabling efficient movement and avoiding accidents.

3. Short Answer Questions.

Q10. Explain any two characteristics of ocean waves.

Answer: The crest is the highest point and the trough is the lowest point of a wave. Wave height is the vertical distance between crest and trough. Wave period denotes the time between two successive crests or troughs at a fixed point.

Q11. Why is the study of tides complex and important?

Answer: Tides show great variation in frequency, magnitude, and height due to factors like the positions of the sun and moon, continental shelves, and coastal shapes. Understanding tides benefits navigation, fishing, and harbour management.

4. Long Answer Questions.

Q12. Describe the major effects of ocean currents on human activities and climate.

Answer: Ocean currents impact climate by transporting warm or cold water to coastal regions, affecting local temperatures. Warm currents create rainy climates on east coasts in tropical and subtropical latitudes, while cold currents on west coasts make areas cooler and often arid. The mixing of currents favours plankton growth, supporting rich fisheries. Currents also determine shipping routes and marine navigation by influencing weather and ocean conditions.

Regulation of coastal climate by heat distribution.
Enhancement of fisheries due to nutrient mixing zones.
Influence on navigation and trade routes.

Q13. How do tides help in the removal of pollutants in river estuaries?

Answer: Tidal movements bring in fresh ocean water and push out polluted and stagnant water during tidal flow and ebb. This helps desilt sediments and reduce pollution in river estuaries, improving water quality for marine and human life.

Ebb flow removes stagnant water.
Regular tidal movement brings dilution.

5. Assertion–Reason type questions.

Assertion (A): Warm ocean currents increase the temperature of coastal regions.
Reason (R): Warm currents transport heat from lower to higher latitudes.

(a) A and R are true, and R is the correct explanation of A
(b) A and R are true, but R is not the correct explanation of A
(c) A is true, but R is false
(d) A is false, but R is true

Answer: (a) Both statements are true and R correctly explains A. Warm currents carry heat, raising temperatures along coasts.

Assertion (A): Spring tides occur only once every six months.
Reason (R): Spring tides require all three—Sun, Moon, and Earth—aligned in a straight line.

(a) A and R are true, and R is the correct explanation of A
(b) A and R are true, but R is not the correct explanation of A
(c) A is true, but R is false
(d) A is false, but R is true

Answer: (d) A is false, but R is true. Spring tides occur twice a month when the Sun, Moon, and Earth are aligned.
