How do ultraviolet rays affect earth
WebOct 2, 2024 · Indeed, Earth’s atmosphere isn’t something we can take for granted. Without it, life as we know it wouldn’t exist. Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet … WebShorter ultraviolet wavelengths of light contain more energy than the infrared or visible portions of sunlight that reach Earth’s surface. Because of this, UV photons can break atmospheric chemical bonds and cause complex health effects. Longer wavelengths (from 320 to 400 nanometers) — called UV-A — cause sunburn and cataracts.

WebMar 2, 2024 · At top of stratosphere, 30 miles high, ozone absorbs most of the harmful ultraviolet radiation from the Sun. At the top of the troposphere, 12 miles high, ozone acts as a greenhouse gas, trapping heat. In the middle of the tropsohere, ozone helps clean up certain pollutants. At the bottom of the troposphere, at Earth's surface, ozone makes smog. WebOnly UVA and UVB ultraviolet rays reach the earth's surface. The earth's atmosphere absorbs UVC wavelengths. UVB rays cause a much greater risk of skin cancer than UVA. …
WebUV Radiation . This fact sheet explains the types of ultraviolet radiation and the various factors that can affect the levels reaching the Earth’s surface. The sun emits energy over a broad spectrum of wavelengths: visible light that you see, infrared radiation that you feel as heat, and ultraviolet (UV) radiation that you can’t see or feel. WebUltraviolet (UV) radiation, which has a shorter wavelength than either visible blue or violet light and is not visible to the human eye, is responsible for sunburns and other adverse …
WebUV-B rays are the harmful rays that cause sunburn. Exposure to UV-B rays increases the risk of DNA and other cellular damage in living organisms. Fortunately, about 95 percent UV-B rays are absorbed by ozone in the Earth's atmosphere.
