Question
Ozone shields the surface of the Earth from which type of radiation coming from the Sun?
The correct answer is
Ultra violet
Ozone Layer Shields Earth from Solar Radiation
The ozone layer, a region in Earth's stratosphere, plays a crucial role in protecting life on the planet.
It acts as a natural filter, absorbing a significant portion of harmful radiation emitted by the Sun.
Radiation Blocked by Ozone
- The primary type of solar radiation absorbed by the ozone layer is Ultra violet (UV) radiation.
- UV radiation from the sun can be harmful, causing issues like skin cancer and cataracts in humans, and damaging plant life.
- While the ozone layer absorbs most UV radiation, some still reaches the surface. It does not significantly block X-rays, visible light (white light), or infra-red radiation.
Therefore, the ozone layer specifically shields the Earth's surface from the damaging effects of Ultra violet radiation.
