What wavelengths of radiation from the sun does the upper atmosphere absorb?
The upper atmosphere absorbs harmful ultraviolet (UV) radiation from the sun. This absorption occurs mainly in the ozone layer, which absorbs UVB and UVC wavelengths. Absorption of these wavelengths protects life on Earth from the damaging effects of excessive UV radiation.
What happens when a molecule absorbs ultraviolet radiation?
When oxygen absorbs UV, it breaks it down. That atom then reacts again with oxygen to form ozone.
What type of radiation does the ozone layer affect?
The ozone layer primarily absorbs and protects against ultraviolet (UV) radiation from the sun, specifically UVB and UVC rays. This absorption helps shield the Earth's surface from the harmful effects of these types of radiation.
What form of EM radiation would be blocked in the stratosphere by ozone?
Ultraviolet (UV) radiation is blocked in the stratosphere by ozone. Ozone absorbs UV radiation, particularly UVB and UVC, helping to protect life on Earth from the harmful effects of excessive UV exposure.
Why doesn't uvc reach us?
UVC radiation is absorbed by the ozone layer in the Earth's atmosphere, which prevents it from reaching the Earth's surface. This protective layer blocks most UVC radiation, shielding us from its harmful effects.
Is UVC a form of ionizing radiation?
No, UVC is not a form of ionizing radiation. UVC is a type of ultraviolet radiation with a wavelength range of 100-280 nm, which is not energetic enough to cause ionization of atoms and molecules.
What happens to uvc radiation?
UVC radiation is absorbed by the ozone layer in the Earth's atmosphere, preventing it from reaching the Earth's surface. If UVC radiation were to reach the surface, it can be harmful to living organisms as it can damage genetic material and cause skin cancer.
Does uvc pass through the earths atmosphere?
No, UVC radiation is mostly absorbed by the Earth's atmosphere, particularly by the ozone layer. This absorption helps to protect living organisms on Earth from the harmful effects of UVC radiation.
What blocks most ultraviolet radiation from entering earths serface?
The ozone layer in Earth's stratosphere mostly blocks ultraviolet radiation from entering the surface. It absorbs the majority of harmful UVB and UVC radiation, allowing only UVA and some UVB radiation to reach the surface.
What wavelengths of radiation from the sun does the upper atmosphere absorb?
The upper atmosphere absorbs harmful ultraviolet (UV) radiation from the sun. This absorption occurs mainly in the ozone layer, which absorbs UVB and UVC wavelengths. Absorption of these wavelengths protects life on Earth from the damaging effects of excessive UV radiation.
What happens when a molecule absorbs ultraviolet radiation?
When oxygen absorbs UV, it breaks it down. That atom then reacts again with oxygen to form ozone.
Why does UVC not affect the skin?
UVC radiation is almost completely absorbed by the ozone layer and does not affect the skin as it doesnt get to us.
What type of radiation does the ozone layer affect?
The ozone layer primarily absorbs and protects against ultraviolet (UV) radiation from the sun, specifically UVB and UVC rays. This absorption helps shield the Earth's surface from the harmful effects of these types of radiation.

Ultraviolet (UV) radiation is blocked in the stratosphere by ozone. Ozone absorbs UV radiation, particularly UVB and UVC, helping to protect life on Earth from the harmful effects of excessive UV exposure.
Why doesn't uvc reach us?
UVC radiation is absorbed by the ozone layer in the Earth's atmosphere, which prevents it from reaching the Earth's surface. This protective layer blocks most UVC radiation, shielding us from its harmful effects.
What dangerous radiation does the atmosphere absorb?
The Earth's atmosphere absorbs harmful ultraviolet (UV) radiation from the sun, particularly UVB and UVC rays. This helps to protect life on Earth from the harmful effects of excessive UV radiation, such as sunburn, skin cancer, and cataracts.
What are 3 types of ultra violet radiation?
The three types of ultraviolet radiation are UVA, UVB, and UVC. UVA has the longest wavelength and is associated with skin aging. UVB has a medium wavelength and is responsible for sunburn and skin cancer. UVC has the shortest wavelength and is mostly absorbed by the ozone layer in the atmosphere.
