Albedo is a unit to describe how reflective an object or a surface is. We use this on Earth as a way to describe how much sunlight (heat) is reflected back into space from the surfaces of our planet. The albedo effect can have a negative impact on our climate. Scientists know that lighter surfaces reflect more light than darker ones, good examples of light surfaces that reflect 80–90% of sunlight are snow and ice. This reflection of sunlight is essential in keeping our planet cool. Without this reflection, Earth's temperatures would increase – causing many environmental problems worldwide by adding to the ongoing global warming caused by greenhouse gas emissions.
Which environment reflects the most light? Rank each environment from 1-4 on whether it is highly reflective (1) or whether itbarely reflects at all (4).
Some surfaces might have similar reflectiveness so you can score these the same.As a bonus question, what are the three "fountains" in the first photo?
