Physics for IGCSE & O level - Thermal Effects (Section 1 - No. 30)
How does the presence of clouds affect the Earth's temperature?
They increase the temperature by absorbing radiation
They decrease the temperature by reflecting radiation
They have no impact on the temperature
They increase the temperature by emitting radiation
Explicación
Clouds reflect sunlight, thus reducing the amount of solar energy absorbed by the Earth and leading to a cooling effect.
