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.



Which material should you use so that the area is cool in terms of temperature?

asphalt
red bricks
concrete
soil

Answer 1

Use soil (preferably with grass/vegetation).

Reason: dark surfaces like asphalt absorb and hold the most heat and get very hot. Vegetated soil stays coolest because it reflects more light and cools by evaporation (evapotranspiration). If you need a paved path, choose light‑colored, permeable paving and add shade and planting to keep the area cool.
