How does the ozone layer form and why is it important?
How does the ozone layer form and why is it important?
Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
How do ozone layer help in sustaining life on earth?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals.
Why is Corona the hottest layer?
Because the coronal material is so thin and tenuous, only a tiny portion of all the sound energy in the photosphere needs to bleed up into the corona and be absorbed in order to heat it to the observed temperatures.
Why is the sun so hot now?
Our sun is the main reason that we have life on our planet. When our sun burst into creation, it was a mass of swirling gases that included a core or center that is compressing atoms together in a process called ‘nuclear fusion’. This intense pressure creates heat at temperatures that are around 15 million degrees C.
Is the corona hotter than the photosphere?
Edlén and Grotrian’s finding that the sun’s corona is so much hotter than the photosphere – despite being further from the sun’s core, its ultimate source of energy – has led to much head-scratching in the scientific community.
Why is the sun so hot today?
The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).
How hot is too hot for humans to survive?
The results suggested that, with the help of a pool of water and a powerful fan, a human could conceivably tolerate heat of up to 140 degrees Fahrenheit in air with 10 percent humidity.
