{'ozone layer': [6, 0, 0, 6], 'cosmic rays': [2, 0, 1, 0], 'infrared rays': [3, 0, 1, 0], 'visible rays': [1, 0, 0, 0]}
The correct answer is option 2 - Ultra-Violet rays. The ozone layer is a protective layer of gas in the Earth`s atmosphere that absorbs most of the Sun`s harmful ultraviolet (UV) radiation. UV radiation can have negative effects on living organisms, such as skin cancer, cataracts, and damage to the immune system. The ozone layer acts as a shield, absorbing and blocking a significant amount of UV radiation from reaching the Earth`s surface. It is important to protect the ozone layer because it plays a crucial role in maintaining the overall health and well-being of our planet.
