We are always exposed to sun rays. The sun gives out radiation consisting of many different frequencies of light. The major component of light it gives off is visible light (which is why our eyes evolved to see visible light best). It also gives off infrared light, ultra violet light, and even more dangerous frequencies. Luckily, the atmosphere of earth filters out a lot of the dangerous frequencies (although not perfectly). If you stay in the sun too much without sunblock, the ultra violet light that gets through the atmosphere can lead to cancer (it's a game of probability). If you go outside of the atmosphere without protection somehow, the rays from the sun become much more dangerous. You would also be susceptable to cosmic radiation, which can lead to cancer.
Of course, the closer you get to the sun, the more concentrated the radiation will be, and the more dangerous it will be.

What time of the year is the northern hemisphere exposed to vertical rays of the sun?
By exposed it to vertical rays of the sun from the spring equinox to the automn equinox.
Why surface exposed to sun is warmer?
I think the reason why it is warmer is because the sun's rays are hitting it directly.
How many rays are on the sun?
there are 6 rays on a sun
What are invisible sun rays called?
U-V rays; Ultra Violet Rays
What happens to temperature as the angle at which the sun's rays strike the earth's surface increases. As the angle decreases. What happens to the length of the shadows at the same time?
pie
What time of the year is the northern hemisphere exposed to vertical rays of the sun?
By exposed it to vertical rays of the sun from the spring equinox to the automn equinox.
What word means a room or place exposed to the sun rays?
That is a solarium.
What happens to trolls when they are exposed to daylight?
They turn to stone when the are exposed in the sun
Why surface exposed to sun is warmer?
I think the reason why it is warmer is because the sun's rays are hitting it directly.
What happens when the stratosphere contians the ozone layer?
It protects us from UV rays. These are harmful rays of the sun.
The tanning effect that occurs when a person is exposed to the sun is exposed to the sun is somewhat protective due to?
Increased production of melanin.
What happen to the molecules of the water when it is exposed to sun rays?
The temperature increase and the motion of molecules is accelerated.
What happens to your eyes when you see sun with your naked eyes?
As intensity of sun light rays are greater so,when we see sun with our naked eyes the sun rays falls on eye lens which is convex which diverges the rays and make it difficult to see
Ultraviolet sun rays responsible for burning skin?
Ultraviolet (UV) sun rays, specifically UVB rays, are responsible for burning the skin and causing sunburn. When the skin is exposed to excessive UVB rays, it can lead to inflammation, redness, and blistering. It is important to protect the skin from these rays by using sunscreen and seeking shade during peak sun hours.
How long is the northern hemisphere exposed to vertical rays of the sun?
Some part of the northern hemisphere is exposed to vertical rays of the Sun from the spring equinox to the autumn equinox (slightly more than half a year because the Earth is further away from the sun during the northern hemisphere summer, it moves slower along it orbit).
What happens to the energy from the suns rays that reach earth?
As the sun's rays heat up the earth, the radiation hits the atmosphere. Then the radiation heads back to the sun.
What takes 80 - 100 years to break down if exposed to the ultraviolet rays of the sun?
non-combustible waste
