Thermosphere
temperature continue to rise up to 1500*C
Ionosphere
Mesosphere
temperature falls to -93*C
Stratosphere
protective ozone layer
UV radiation causes temperature to rise
Troposphere

temperature drops from 17 to -52*C
Explanation:
It’s d. The time it takes for the water to boil. It is adding different amounts of salt to see which one will boil quicker if adding an amount of salt.
Answer:
Correct
Explanation:
Because the light can't travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water. Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.
Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
