sunburn comes from receiving too much infra-red rays directly from the Sun (lying in direct sunlight).
Infra-red rays are long wave length, and the longer the wavelength the more penetrating, they can pass through denser/thicker matter. However, the upper atmosphere, the ozone layer, stops a lot of infra-red waves reaching the Earth, but not all. So in lying in direct sunlight, IR waves are passing through you, hence burning.
In comparison ultra-violet (UV) waves are shorter wavelength and less penetrating, but more damaging to the surface they pass through.
If you are mind full of having a nice Sun-tan . The best advise is sit in the shade, with a cold drink alongside you. You will receive all the UV light that you need for a good sun-tan, but will not be sun-burnt.
Yes!!! it seems a bit obtuse, but it works, and it was the advice I was given many years ago by a doctor, and ??? you don't need sunscreens/creams????
What else can I help you with?
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.
Is an ozone layer part a cake?
No ozone is not a park of a cake. The ozone is a very important part of the atmosphere. A cake won't protect us from the UV rays of the sun.No, it is not. It is a part of atmosphere.
How those the atmosphere protect us?
Its like an invisible barrier It protects us from the hard hard hard rays from the sun
How do you protect myself from gamma radiations?
Generally, the atmosphere and magnetic field protect us from gamma rays. Refer to the related link for more information.
What does a house protect us from?
Well, not everything, but most things like: Bugs, birds and other animals. And it keeps you from getting wet when I rains and...getting a sunburn. Dunno what else to list...
Does the atmosphere protect us from ozone?
Yes and no some ozone still gets through which causes sunburn and other damages
Does the atmosphere protect us from meteorites?
YES
What in your body that protect you from sunburn?
Melanin :)
Does the earth atmosphere protect us from zero gravity?
No
Why do giraffes have blue tonges?
protect it from sunburn
How does your atmosphere protect us?
Our atmosphere also reflects UV and makes meteors burn up.
How do the layers of the earth work?
The various layers of atmosphere protect us. They protect us from the UV rays, Control the temperature etc.
Does the atmosphere protect us from the suns UV rays?
Yes, the atmosphere protects us from the sun's Uv rays. The ozone layer does this job.
What is the earths atmosphere's purpose?
to protect us from the sun's harmful rays
How does the atmosphre protect us from uv rays?
The atmosphere protect us from UV. The main reason behind it is ozone present as ozone layer.
How do the layers of the earth work together?
The Earth is NOT an inert lump of rock flying round in space, but a very DYNAMIC system. The core of the Earth is hot liquid metal ( iron/nickel) mwhich rotates counter-clockwise to Earth's rotation. It also gives the Earth its magnetism *compass points). Outside the core the mantle, which convects, like water in a kettle, but much more slowly. This convection is driven by the heat of the core. The convecting mantle in turn moves the tectonic plates, mountains, earthquakes, volcanoes, ocean currents etc., The ocean currents form part of the hydro-sphere, which overlaps with the bio sphere ( all living matter). , which in turn is overlapped by the atmosphere. Then the stratosphere , and the ionosphere. From the hydro sphere outwards the Sun through gravity and radiation drives the whole system. The Sun through radiation gives us light and heat. The light radiation drives photosynthesis for plants to absorb CO2, and release oxygen. The are similar cycles for carbon and nitrogen. The Sun's gravitational attraction keeps Earth on its orbital track, otherwise we would 'fly-off' into outer space, and Earth would die, no sunlight. Also we rotate once a day to give us night and day . Our angle of rotation is angled at about 23 degrees and decreasing, this gives us our seasons. This axial angle of 23 degrees is currently decreasing to about 21 degrees and will then increas to about 28 degrees; it is called precession. It will affect climate change, and the polar ice caps , currently receding. Also our orbital track about the Sun is an ellipse which widens to nearly circular and then slims to a very narrow ellipse. This ellipse does not close up every year , but slightly overlaps. The Moon coupled with the Sun gives us our ocean tides. The mechanics of which are quite complicated, but understood. There is a lot more going on in/on Earth, that I have not mentioned. I leave you to try and find out for yourself. I hope from this, you understand that natural events, climate change included, on Earth are driven by many different forces, of which mankind has no control , but is only just beginning to understand. A lot of these events have been observed on other Solar System planets, the Martian ice caps changing size. The orbit of Mercury overlapping etc., The Earth is no different. If we lived on an inert lump of rock , no seasons, , no night and day, NOTHING!!!!!
How does your hair protect us?
Hair protects your head by being a shield for it, such as, it prevents harsh sunburn, it keeps you warm. HAHA and it's also for looks.
