More fill in the blanks?!?

The scale used to help judge how much time in the Sun would cause sunburn is called (blank). On a clear day in July in southern Canada, a typical value on this scale is about (blank)





For this question would it be Humidex Scale and 30- 40 degrees?





Name the part of the electromagnetic spectrum that: we can see (blank); comes from the Sun amd can be absorbed by upper-level ozone (blank); is radiated by the ground and other objects as they are cooling down (blank); is used in Doppler radar system (blank)





Much help would be appreciated!!

It is the UV Index


http://www.cpc.ncep.noaa.gov/products/st...


THE UV INDEX IS CATEGORIZED BY THE WORLD HEALTH ORGANIZATION


AS FOLLOWS:


UVI EXPOSURE LEVEL


0 1 2 LOW


3 4 5 MODERATE


6 7 HIGH


8 9 10 VERY HIGH


11 AND GREATER EXTREME





Humidity is based on the percentage of moisture in the atmosphere.


Remember that Cold air can hold less moisture than warm air.





Name the part of the electromagnetic spectrum that: we can see (Light);

Stratosphere


The Stratosphere extends from the tropopause up to 31 miles above the Earth%26#039;s surface. This layer holds 19 percent of the atmosphere%26#039;s gases and but very little water vapor.





comes from the Sun amd can be absorbed by upper-level ozone (ultraviolet radiation);


Temperature increases with height as radiation is increasingly absorbed by oxygen molecules which leads to the formation of Ozone. The temperature rises from an average -76掳F (-60掳C) at tropopause to a maximum of about 5掳F (-15掳C) at the stratopause due to this absorption of ultraviolet radiation. The increasing temperature also makes it a calm layer with movements of the gases slow.





The regions of the stratosphere and the mesosphere, along with the stratopause and mesopause, are called the middle atmosphere by scientists. The transition boundary which separates the stratosphere from the mesosphere is called the stratopause.

is radiated by the ground and other objects as they are cooling down (Radiation);

is used in Doppler radar system (short bursts of radio waves, called pulses)

I can only answer one and that%26#039;s





%26quot;Name the part of the electromagnetic spectrum that: we can see (visible light/visible spectrum)%26quot;





We just learned about the visible spectrum, and light, but I%26#039;m not sure about the ozones,ect.





Sorry I couldn%26#039;t be of much help.
