A renewable energy source is a natural resource on Earth that can be naturally replenished in a short period of time. Wind is considered clean and renewable because it will not produce harmful pollutants or emissions and won't harm our ecosystem!
Answer:
e. is produced by the absorption of UV radiation.
Explanation:
The thermosphere is a layer of Earth's atmosphere which is directly above the mesosphere and below the exosphere. It extends from about 85 to 500 km altitude above the earth.
In the thermosphere, the temperature is strongly dependent on the level of solar activity. When the Sun is very active and emitting more high energy radiation, the thermosphere becomes hotter by X-ray and UV radiation absorption.
So a 1st magnitude star is 2.512 times brighter than a 2nd magnitude star, and 2.5122=6.31 times brighter than a 3rd magnitude star so your answer would be a second-magnitude star is brighter than a third-magnitude star

- Combustion of natural gas releases carbon dioxide into the atmosphere.
- Coal and oil are fossil fuels that release toxic materials into the atmosphere too.
