Question 1 of 5
1. Question
Consider the following statements.
- The periodical rise and fall of the sea level, once or twice a day, caused by meteorological
effects are called tides.
- Centrifugal force also causes for the occurrence of tides.
Which of the above statements is/are correct?
Correct
Solution: b)
The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of
the sun and the moon, is called a tide.
Movement of water caused by meteorological effects (winds and atmospheric pressure changes) are called surges.
The moon’s gravitational pull to a great extent and to a lesser extent the sun’s gravitational pull, are the major causes for the occurrence of tides. Another factor is centrifugal force, which is the force that acts to counter balance the gravity. Together, the gravitational pull and the centrifugal force are responsible for creating the two major tidal bulges on the earth.

Question 2 of 5
2. Question
Consider the following statements.
- During the day time the intensity of tides is always uniform along the coastline.
- The position of both the sun and the moon in relation to the earth has direct bearing on tide height.
- Neap tides occur when the sun, the moon and the earth are in a straight line.
Which of the above statements is/are incorrect?
Correct
Solution: c)
The shape of bays and estuaries along a coastline can also magnify the intensity of tides.
The position of both the sun and the moon in relation to the earth has direct bearing on tide height. When the sun, the moon and the earth are in a straight line, the height of the tide will be higher. These are called spring tides and they occur twice a month, one on full moon period and another during new moon period.
Normally, there is a seven day interval between the spring tides and neap tides. At this time the sun and moon are at right angles to each other and the forces of the sun and moon tend to counteract one another.

Question 3 of 5
3. Question
Consider the following statements.
- Unlike Cyclones and Ocean currents, tides cannot be predicted well in advance.
- Ocean currents are influenced by Gravitational force and Coriolis force.
- The level of ocean water is lower in equator than in the middle latitudes, because of the Coriolis effect.
Which of the above statements is/are correct?
Correct
Solution: b)
Since tides are caused by the earth-moon-sun positions which are known accurately, the tides can be predicted well in advance.
Ocean currents are like river flow in oceans. They represent a regular volume of water in a definite path and direction.
The primary forces that influence the currents are: (i) heating by solar energy; (ii) wind; (iii) gravity; (iv) coriolis force.
Heating by solar energy causes the water to expand. That is why, near the equator the ocean water
is about 8 cm higher in level than in the middle latitudes. This causes a very slight gradient
and water tends to flow down the slope.

Question 4 of 5
4. Question
With reference to the temperate cyclones, which of the following statements is/are correct?
- They flow in west to east direction.
- They often come under the influence of westerlies.
- They have swift and unpredictable movement.
- Western disturbances in India is due to temperate cyclone.
Select the correct answer code:
Correct
Solution: c)
Westerlies are not swift as tropical cyclone and their direction can be predicted.
Incorrect
Solution: c)
Westerlies are not swift as tropical cyclone and their direction can be predicted.
