Answer:
Human actions involve the release of halogen source gasses containing chlorine and bromine atoms. These pollutants into the atmosphere eventually contribute to the loss of stratospheric ozone. Halons are also discharged immediately into the atmosphere due to these uses.

Desertification affected the land in Africa because of poor soil structure, and low productivity in agriculture and it forces migration for farmers and livestock. The correct option is a, d and e.
What is desertification?Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. It is the spread of arid areas caused by a variety of factors, such as climate change and overexploitation of soil as a result of human activity.
Throughout geological history, the development of deserts has occurred naturally. In recent times, the potential influences of human activity, improper land management, deforestation and climate change on desertification is the subject of many scientific investigations. The world's most noted deserts have been formed by natural processes interacting over long intervals of time.
During most of these times, deserts have grown and shrunk independently of human activities.

Answer:
hope it becomes helpful to you ☺️
Explanation:
The troposphere is wider at the equator (10mi) than at the poles (5mi). ... Water vapor concentration varies from trace amounts in Polar Regions to nearly 4 percent in the tropics. Most prevalent gases are nitrogen (78 percent) and oxygen (21 percent), with the remaining 1- percent consisting of argon,).
Answer:
Most prevalent gases are nitrogen (78 percent) and oxygen (21 percent), with the remaining 1- percent consisting of argon, (. 9 percent) and traces of hydrogen ozone ( a form of oxygen), and other constituents. Temperature and water vapor content in the troposphere decrease rapidly with altitude.
