The troposphere is made up of several different gases. And, there are a couple of interesting things about the gases. The first is that the troposphere is made of 78% nitrogen, which is by far and away the most plentiful gas in our air. Also, oxygen, the gas that is so crucial to life on the planet, only makes up 21% of the air. All the other gases combined make up the remaining 1%, including carbon dioxide.

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.
