Information gathered about the Earth's surface from above is called what?

• A. Quadrat
• B. Quota
• C. Rainwater harvesting
• D. Remote sensing

Answer: (D)

Remote sensing is information gathered about the Earth's surface from above. It uses sensors on satellites, airplanes, or drones to observe land, water, and vegetation without touching the ground, allowing big areas and changes over time to be monitored. This is invaluable in environmental management for mapping land use, tracking deforestation, assessing crop health, and studying how landscapes evolve or respond to natural events. In contrast, a quadrat is a small, defined ground-area sampling method used to count organisms or measure features directly on the ground. A quota refers to a limit on how much of a resource can be taken or sold. Rainwater harvesting is about collecting and storing rainwater for use, not about observing surface features.
