If you saw a picture of earths surface as seen from above in which water looked black forests looked red and cities looked blue-gray you are probably looking at a?

Answer 1

You are likely looking at a false-color satellite image, which uses infrared and other wavelengths to represent different features of the Earth's surface. In such images, water can appear black or dark due to its absorption of infrared light, while healthy vegetation like forests may appear red due to their reflective properties in the near-infrared spectrum. Urban areas often show up in blue-gray hues due to the materials used in construction, which reflect light differently than natural landscapes. This technique is commonly used in remote sensing to analyze environmental changes and land use.
