• Question 1 of 5 1. Question Consider the following statements regarding the influence of air masses on weather: The moisture content of an air mass determines its ability to cause precipitation when it moves over land. Cyclones and storms often develop in the contact zones between different air masses. Stable air masses are more likely to cause storms and precipitation due to their vertical temperature profile. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 1 is correct. The moisture content of an air mass, particularly maritime air masses, plays a key role in determining whether it will cause precipitation when it moves over land. If the air mass contains sufficient moisture, it can lead to cloud formation and precipitation, especially when it encounters cooler land surfaces. Statement 2 is correct. Cyclones, storms, and other atmospheric disturbances often arise at the boundaries between different air masses (fronts). The contrasting temperatures, humidities, and pressures between these air masses create the instability that drives storm formation. Statement 3 is incorrect. Stable air masses tend to suppress vertical movement and are generally associated with clear, calm weather, not storms or precipitation. Unstable air masses, on the other hand, encourage vertical motion, which leads to cloud formation and storms. Incorrect Solution: b) Statement 1 is correct. The moisture content of an air mass, particularly maritime air masses, plays a key role in determining whether it will cause precipitation when it moves over land. If the air mass contains sufficient moisture, it can lead to cloud formation and precipitation, especially when it encounters cooler land surfaces. Statement 2 is correct. Cyclones, storms, and other atmospheric disturbances often arise at the boundaries between different air masses (fronts). The contrasting temperatures, humidities, and pressures between these air masses create the instability that drives storm formation. Statement 3 is incorrect. Stable air masses tend to suppress vertical movement and are generally associated with clear, calm weather, not storms or precipitation. Unstable air masses, on the other hand, encourage vertical motion, which leads to cloud formation and storms.

• Question 2 of 5 2. Question Consider the following statements regarding the importance of continental shelves: Continental shelves are important for fisheries because plankton growth is abundant in these shallow waters. Petroleum extraction is primarily done in deep ocean waters and not on continental shelves. Coral reefs are commonly found in the deep ocean, far from continental shelves. Which of the statements given above is/are correct? a) 1 and 2 only b) 2 and 3 only c) 1 only d) 1, 2, and 3 Correct Solution: c) Statement 1 is correct. The shallow waters of the continental shelf allow sunlight to penetrate to the seabed, supporting the growth of plankton, which serves as food for many fish species. This makes continental shelves highly productive fishing grounds. Statement 2 is incorrect. Petroleum extraction is primarily carried out on continental shelves, where significant oil and natural gas reserves are found, such as in the Bombay High and Godavari basin regions. Statement 3 is incorrect. Coral reefs are often found on continental shelves, where the warm, shallow waters provide ideal conditions for coral growth. Reefs do not typically form in the deeper parts of the ocean. Incorrect Solution: c) Statement 1 is correct.
