• Question 1 of 10 1. Question 1 points Which of the following statements accurately describes crop diversification? (a) Crop diversification refers to the practice of cultivating a single crop variety throughout the year. (b) Crop diversification involves the cultivation of multiple crops on a rotating basis within a farming system. (c) Crop diversification primarily focuses on maximizing the yield of a single cash crop. (d) Crop diversification is only beneficial for large-scale commercial farms. Correct Ans: (b) Explanation: Context: West Bengal farmers are shifting from wheat cultivation to more lucrative options like bananas, lentils, and maize, especially in border districts like Murshidabad and Nadia. Crop diversification is the practice of growing a variety of crops on the same land, either sequentially or in a crop rotation system. This helps in mitigating risks associated with mono-cropping, enhancing soil fertility, and promoting ecological balance.

• Question 3 of 10 3. Question 1 points In a tropical cyclone, as you move from the edges towards the center, air pressure (a) remains constant (b) increases significantly (c) decreases significantly (d) varies depending on the wind speed and direction Correct Ans: (c) Explanation: Tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center. On Earth, the pressures recorded at the centers of tropical cyclones are among the lowest ever observed at sea level. At the center of a mature tropical cyclone, air sinks rather than rises. For a sufficiently strong storm, air may sink over a layer deep enough to suppress cloud formation, thereby creating a clear “eye”. If the air pressure is high at the center and low at the edges, an anti-cyclone is formed.

• Question 8 of 10 8. Question 1 points Which of the following statements about algal blooms is true? (a) Algal blooms occur due to the sudden influx of nutrients into aquatic ecosystems. (b) Algal blooms are always beneficial for the environment. (c) Algal blooms are primarily caused by a decrease in water temperature. (d) Algal blooms have no impact on marine life. Correct Ans: (a) Explanation: Context: A panel formed by the National Green Tribunal (NGT) investigated the red colouration of the sea in Puducherry and attributed it to a plankton crash. A specific species of phytoplankton, Noctiluca scintillans, was found to be ruptured, releasing red pigment into the sea. The panel ruled out algal bloom and contamination from a nearby paper manufacturing unit, stating that the unit’s operations did not coincide with the discolouration incidents. Instead, the panel identified high iron concentration as a potential factor favouring plankton bloom. Environmental parameters such as sea surface temperature, salinity, pH, and dissolved oxygen were found conducive to the proliferation of this species. Algal blooms are rapid increases in the population of algae in aquatic ecosystems. Option A is correct because algal blooms typically occur when there is an excess of nutrients, such as nitrogen and phosphorus, entering the water, often due to runoff from agricultural or urban areas, which leads to an overgrowth of algae. This sudden influx of nutrients fuels the rapid growth of algae, causing a bloom. Options B, C, and D are incorrect because algal blooms can have negative impacts on the environment, are not exclusively beneficial, are not primarily caused by a decrease in water temperature, and do have significant impacts on marine life due to factors such as oxygen depletion and toxins released by certain types of algae during blooms.
