commonly 'sunlight', but more specifically UltraViolet radiation
Ultraviolet radiation is blocked from reaching the Earth's surface by the ozone layer found in the atmosphere. The ozone layer absorbs most of the Sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface and causing damage to living organisms.
The Earth's surface layer is called the crust.
No, they cannot be blocked. The Ozone layer can only block the UV rays of the sun.
No. the layer that actually reaches the surface is the troposphere.
