Question

your team must design an area in your school where students can relax between classes. you need to choose a material for a walkway. the materials you need to consider are in the table.
material | albedo (%)
asphalt | 5–10
red bricks | 36
concrete | 15–25
soil | 10–25
which material should you use so that the area is cool in terms of temperature?
○ asphalt
○ red bricks
○ concrete
○ soil

Explanation:

Albedo is the measure of the reflectivity of a surface. A higher albedo means more solar radiation is reflected, and less is absorbed (which would lead to heating). Among the given materials, red bricks have the highest albedo (36%). So, using red bricks would result in more solar radiation being reflected, keeping the area cooler.

Answer:

red bricks
