Identity three processes in which a rooftop garden can reduce the heat absorbed., compared to an asphalt roof. Select the three correct answers.
1) Evapotranspiration: Rooftop gardens can release moisture through evapotranspiration, which can help to cool the surrounding air and reduce the heat absorbed by the roof. This process is not typically present in asphalt roofs.
2) Shading: The plants, trees, and other greenery in a rooftop garden can provide shade to the roof, reducing direct exposure to the sun's rays and therefore reducing the heat absorbed.
3) Insulation: The layers of soil, plants, and other materials in a rooftop garden can act as insulation for the roof, providing a buffer against extreme temperature changes and reducing heat absorption. Asphalt roofs, on the other hand, do not have this insulation property.
