Question 1 of 20
1. Question
2 pointsConsider the following statements:
1. Equatorial counter current is more strongly developed in the Pacific Ocean than in the Atlantic ocean
2. Equatorial counter current flows in the westward direction
Which of the statements given above is/are correct?
Correct
The Equatorial counter current is developed strongly in the Atlantic Ocean than in the Pacific ocean. This is because of the shorter distance between landmasses Africa and South America compared to South America and the South East Asian landmasses. Further South East Asian landmasses and Australia are disjointed and are unable to provide a strong landmass for the flow of counter-current, unlike South America.
Equatorial counter-current flows eastward and not westward.
Hence, both statements are not correct.

Question 8 of 20
8. Question
2 pointsWith reference to the thermocline, consider the following statements:
1. It is the boundary region below sea level where temperature uniformly decreases with increasing depth.
2. About 90 per cent of the total volume of water is found below the thermocline in the deep ocean.
Which of the statements given above is/are incorrect?
Correct
-The temperature-depth profile for the ocean water shows how the temperature decreases with the increasing depth. The profile shows a boundary region between the surface waters of the ocean and the deeper layers.
-The boundary usually begins around 100 – 400 m below the sea surface and extends several hundred of m downward. This boundary region, from where there is a rapid decrease of temperature, is called the thermocline.
So, statement 1 is not correct.
-About 90 per cent of the total volume of water is found below the thermocline in the deep ocean. In this zone, temperatures approach 0° C.
Statement 2 is correct.
-The second layer called the thermocline layer lies below the first layer and is characterised by rapid decrease in temperature with increasing depth. The thermocline is 500 -1,000 m thick.

Question 9 of 20
9. Question
2 pointsConsider the following statements about albedo:
1. It is the fraction of Sun’s radiation reflected from a surface
2. The albedo of Mercury is much greater than the albedo of the Earth.
Which of the statements given above is/are incorrect?
Correct
-The term albedo (Latin for white) is commonly applied to the overall average reflection coefficient of an object. Hence statement 1 is correct.
For example, the albedo of the Earth is 0.37 (de Pater and Lissauer) and this affects the equilibrium temperature of the Earth. The greenhouse effect, by trapping infrared radiation, can lower the albedo of the earth and contribute to global warming.
The albedo of an object will determine its visual brightness when viewed with reflected light. For example, the planets are viewed by reflected sunlight and their brightness depends upon the amount of light received from the sun and their albedo. Mercury receives the maximum amount of sunlight, but its albedo is only 0.1 so it is not as bright as it would be with a higher albedo.
Thus statement 2 is incorrect.

Question 11 of 20
11. Question
2 pointsWith reference to sub-tropical high-pressure belt, consider the following statements:
1. The sub-tropical highs extend from near the tropics to about 35°N and S.
2. It is dynamically induced and characterized with anti-cyclonic conditions
Which of the statements given above is/are incorrect?
Correct
-The sub-tropical highs extend from near the tropics to about 35°N and S.
Hence, statement 1 is correct.
-The pressure belt is dynamically induced as it owes its origin to the rotation of the earth and sinking and settling of winds. This zone is characterized by anticyclonic conditions which cause atmospheric stability and aridity. Thus, most of the hot deserts of the world are present in this region extending between 25-35 degrees in both the hemisphere.
Thus statement 2 is correct.

Question 12 of 20
12. Question
2 pointsConsider the following statements
1. Hydrolysis is a form of chemical weathering that involves
the rigid attachment of H+ and OH- ions to the atoms and molecules of a
mineral.2. Hydration is a chemical weathering process that involves
the reaction between mineral ions and the ions of water.Which of the above statements is/are incorrect?
Correct
Hydration is a form of chemical weathering that involves the rigid
attachment of H+ and OH- ions to the atoms and molecules of a mineral.Hydration is a form of chemical weathering in which the chemical bonds of the mineral are changed as it interacts with water. One instance of hydration occurs as the mineral anhydrite reacts with groundwater. The water transforms anhydrite into gypsum, one of the most common minerals on Earth.
Hence, statement 2 is not correct.
Hydrolysis is a chemical weathering process that involves the reaction between mineral ions and the ions of water (OH- and H+) and results in the decomposition of the rock surface by forming new compounds.
In the process of hydrolysis, a new solution(a mixture of two or more substances) is formed as chemicals in rock interact with water. In many rocks, for example, sodium minerals interact with water to form a saltwater solution.
Hence, statement 1 is not correct.

Question 13 of 20
13. Question
2 pointsConsider the following statements:
1. Trades wind blow out from the Subtropical High-Pressure belts. In the northern hemisphere, they blow towards the equatorial low and called North East Trade Winds. In the Southern hemisphere, they blow towards the equatorial low and become the South East Trade winds.
2. Westerlies blow in the middle latitudes between 30 and 60 degrees latitude and originate from the high-pressure area in the horse latitudes towards the poles.
Which of the above statements is/are correct?
Correct
-Trades wind blow out from the Subtropical High-Pressure belts. In the northern hemisphere, they blow towards the equatorial low and called North East Trade Winds. In the Southern hemisphere, they blow towards the equatorial low and become the South East Trade winds. This implies that Trade winds blow from northeast towards the equator in Northern hemisphere and South East Towards equator in the southern hemisphere. Hence, statement 1 is correct.
-The directions of the Westerlies are opposite to trade winds and that is why they are also called antitrade winds. Westerlies blow in the middle latitudes between 30 and 60 degrees latitude and originate from the high-pressure area in the horse latitudes towards the poles. Under the effect of the Coriolis force, they become the south-westerlies in the northern hemisphere and Northern westerlies in the southern hemisphere.
Hence, statement 2 is correct.
Please note that in the southern hemisphere, there is more of ocean and less of land in comparison to the northern hemisphere. Due to this reason, the westerlies blow with much greater force in the southern hemisphere in comparison to the northern hemisphere.

1. Western Disturbances is important for Rabi crop in the Northern Subcontinent.
2. Western Disturbances originate from Caspian Sea only as extra-tropical cyclone.
Which of the following statements is/are incorrect?
Correct
• Western Disturbance is a low-pressure area or a trough over the surface or the upper-air in the westerly winds regime, north of 20°N, causing changes in pressure, wind pattern and temperature fields.
• Western Disturbances originate in the Caspian Sea or the Mediterranean Sea as extra-tropical cyclones. They gradually travel across the middle-east from Iran, Afghanistan, and Pakistan to enter the Indian sub-continent.
• Though Western Disturbances move across the Indian region throughout the year, they are in their peak during winter months of January and February. Their effect is minimal during the monsoon months in India.
• They bring winter and pre-monsoon rain and is important for the development of the Rabi crop in the Northern subcontinent. Winter rainfall in Northern India brought by them cause development of Anticyclonic conditions with low temperatures

Question 19 of 20
19. Question
2 pointsWhich of the following causes adiabatic temperature changes in the atmospheres?
Correct
In thermodynamics, an adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred to its surroundings only as work.
-When the pressure applied on a parcel of air is reduced, the air in the parcel is allowed to expand; as the volume increases, the temperature falls as its internal energy decreases. Adiabatic cooling occurs in the Earth’s atmosphere with orographic lifting and lee waves, and this can form pileus or lenticular clouds.
