The water droplets in your breath would simply freeze more quickly than when it is a less extreme temperature (e.g. 10 degrees Fahrenheit). Your breath may appear to "sink" more quickly than in more normal temperatures, but little else would change.
However, the likelihood of -90 degrees Fahrenheit in populated areas, those outside of Antarctica, the extreme Arctic, and the peaks of tall mountains, is small-even in those areas. The coldest temperature ever recorded was -129 degrees Fahrenheit at Vostok Station, Antarctica on July 21st, 1983; so while -90 degrees is certainly possible, it is incredibly unlikely outside of the poles and the tops of the tallest mountains in the world.
for a breath
it freshens your breath.
it helps us breath

breath is another name for width
The reason you can see your breath in cold weather is because the water vapor in your breath is condensing (condensation). You can't see it in hot weather because condensation can't occur in warmer weather.
carbon dioxide is released into the air.
you first breath in and then you breath out
Because of condensation. When a glass of ice has vapor on the outside of it, it's because cold met heat. The same thing happens when heat meets cold, your breath turns to vapor.
When you inhale, you breath in oxygen and your lungs get bigger.
if it is 32 degrees Fahrenheit or 0 degrees Celsius, than when you breathe out the water in your breath condenses in the air
NOSE!
then we could not breath.
Your breath is substantially colder than the outside air... when your warm breath suddenly is immersed in that cold air, it forms condensation.
it goes up and out
Bad breath
you die
