Guida verificata passo dopo passo1
Understand the role of each sphere mentioned in the problem: Hydrosphere (water bodies), Atmosphere (air and gases surrounding Earth), Geosphere (solid Earth), and Biosphere (living organisms).
Recall that harmful solar radiation, such as ultraviolet (UV) rays, is primarily blocked by a layer of gases in Earth's atmosphere, specifically the ozone layer.
Learn that the ozone layer, located in the stratosphere (a part of the atmosphere), absorbs and prevents most of the harmful UV radiation from reaching Earth's surface.
Eliminate the other options: The hydrosphere, geosphere, and biosphere do not have mechanisms to block solar radiation; their roles are unrelated to this function.
Conclude that the correct sphere responsible for protecting Earth's surface from harmful solar radiation is the atmosphere.
