#1. Westerlies in southern hemisphere are stronger and persistent than in northern hemisphere. Why? 1. Southern hemisphere has less landmass as compared to northern hemisphere. 2. Coriolis force is higher in southern hemisphere as compared to northern hemisphere. Which of the statements given above is/are correct ?

1 only

1 and 2 both

2 only

None

#2. Which of the following indicates the correct sequences of the topographical features beneath the surface of the sea?

Shelf - slope - trench - rise - continent

Continent - shelf - rise - slope - trench

Continent - shelf - slope - rise - abyssal plain

Continent - slope - abyssal plain - shelf

#3. Which of the following conditions occur during an EINino? 1. Trade winds are weakened in the Eastern Pacifc. 2. Up-welling across the coast of Peru is suppressed and warm surface water remains across the coast. 3. Air pressure rises over large areas of the South-East pacifc, while pressure drops over Western Pacifc. 4. Release of H 2S in the water off the coast of Peru.

2 and 3

1, 2 and 4

1 and 2

1, 2, 3 and 4

#4. Which of the following statements about the trade winds are not true?

Trade winds blow from sub-tropical high pressure areas towards equatorial low pressure areas

Because of the coriolis effect the trade winds are deflected in anti-clockwise direction to become North-East trades in the Northern hemisphere and in clockwise to become North-East trades in the Northern hemisphere and in clockwise to become South-East trades in the Southern hemisphere

Trade winds are descending and stable. Hence, they are dry in the place of origin

(a) Trade winds are also called as Easterlies (b) (d) T

#5. Which of the following cannot be the outcome of global warming? 1. The frequency of hot extremes, heat waves and heavy precipitation will very likely decreases. 2. The most warming will be at high Northern latitudes and least warming over the Southern ocean and parts of the North Atlantic ocean. 3. Increased coastal ﬂooding. 4. Climate change so far includes adverse effects on small islands, adverse effects on indigenous populations in high-latitude areas. Select the correct answer using the codes given below:

1, 2 and 3

2 and 3

1 only

None

#6. Which of the following are the causes of upwelling in the oceans? 1. Wind 2. Coriolis force 3. Density shifts 4. Ekman transport Select the correct answer using the codes given below:

1 and 2

1, 2 and 4

1 and 3

2, 3 and 4

#7. Which of the following are the causes of upwelling in the oceans? 1. Wind 2. Coriolis force 3. Density shifts 4. Ekman transport Select the correct answer using the codes given below:

1 and 3

1 and 2

1, 2 and 4

2, 3 and 4

#8. Upwelling is an oceanographic phenomenon that involves motion of dense, cooler and usually nutrient-rich water towards the ocean surface driven by?

Wind

Volcanic activity

Tides

Earthquake

#9. What would happen if phytoplankton of an ocean is completely destroyed for some reason? 1. The ocean as a carbon sink would be adversely affected. 2. The food chains in the ocean would be adversely affected. 3. The density of ocean water would drastically decrease. Select the correct answer using the codes given below:

1, 2 and 3

1 and 2

2 only

3 only

#10. At night, the winds generally die out. This is because

convection during daytime causes mixing of air and therefore, spreads up the wind near the surface

the Coriolis deﬂection is greater during daytime (

temperature inversion prevents any exchange of air from the upper layer to the lower layer

the conditions are quite during night time

#11. Consider the following statements about tropical cyclone: 1. It is characterised by a low-pressure centre. 2. In this, counter clockwise wind ﬂow in the Northern Hemisphere and clockwise wind ﬂow in the Southern Hemisphere. 3. It was a warm core storm system. Which of the above statements are correct?

1, 2 and 3

1 and 3

1 and 2

2 and 3

Finish
