• Question 1 of 5 1. Question Consider the following statements regarding the global impact of volcanic eruptions: Large-scale volcanic eruptions can lead to a temporary cooling of the Earth’s climate due to sulfur dioxide emissions. Volcanic eruptions contribute to the formation of new landmasses, such as the Hawaiian Islands. Volcanic eruptions have no effect on global ocean circulation. Some volcanic eruptions release gases that contribute to the depletion of the ozone layer. Which of the above statements are correct? (a) 1, 2, and 4 (b) 2, 3, and 4 (c) 1 and 3 only (d) All of the above Correct Solution: A Statement 1 is correct. Large volcanic eruptions inject massive quantities of sulfur dioxide (SO₂) into the stratosphere. This gas reacts with water vapor to form sulfate aerosols, which reflect incoming solar radiation back into space. The result is a temporary global cooling effect lasting months to a few years. Historic eruptions like that of Mount Pinatubo demonstrated measurable global temperature decline following such aerosol formation. Statement 2 is correct. Volcanic activity is a fundamental process in the creation of new landmasses. Hotspot volcanism beneath oceanic plates forms volcanic island chains over time. The Hawaiian Islands are a classic example, formed by the Pacific Plate moving over a stationary mantle plume. Statement 3 is incorrect. Volcanic eruptions can influence ocean systems. Submarine eruptions alter ocean chemistry and temperature locally, while volcanic ash deposition can modify nutrient cycles and affect marine productivity. Large-scale climatic cooling from volcanic aerosols can also influence ocean circulation patterns indirectly. Statement 4 is correct. Certain volcanic eruptions release halogen compounds such as chlorine and bromine. When injected into the stratosphere under suitable conditions, these can participate in chemical reactions that contribute to ozone depletion. Incorrect Solution: A Statement 1 is correct.

Which of the above statements are correct? (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Correct Solution: C Statement 1 is correct. Remote sensing is the technique of acquiring information about objects, features, or phenomena without direct physical contact. It is typically carried out using sensors mounted on satellites, aircraft, drones, or even ground-based platforms. This technology enables large-scale monitoring of Earth’s surface, oceans, and atmosphere. Applications include agriculture monitoring, weather forecasting, disaster management, environmental assessment, and defence surveillance. Statement 2 is correct. Remote sensing systems collect data by detecting electromagnetic radiation. In optical remote sensing, sensors measure solar radiation reflected from the Earth’s surface. In thermal remote sensing, sensors detect emitted radiation.
