why would you find airlines flying over stratosphere?
there are fewer clouds in this layer, making Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere. a much smoother ride overall.airplanes fly in the stratosphere is because this is where the least amount of turbulence is found.

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.

why is troposphere so important for the existence of humans and natural environment on Earth?
Explanation:
The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth's Atmosphere, as it is the layer that we live in and the layer that gives us weather.
Answer: short answer it provides the air we need to survive
Explanation: long answer
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. Also regulates our weather and temperatures on a regular basis

Answer:
An economic system is the decision-making structure of a nation’s economy, characterized by the entities and policies that shape it.
An economic system may involve production, allocation of economic inputs, distribution of economic outputs, firms, and the government to answer the economic problem of resource allocation.
There are two general subtypes of economic systems: free market systems and planned systems.
A country may have some elements of both systems, and this type of economy is known as a mixed economy.
The climatic temperature on average is varying due to the natural conditions of the places if location A is situated in more hilly areas then location B would result in a change in temperate.
What factors are responsible for differences in temperature in different locations? The changes would arise due to human activities resulting in high temperature in one location because of high industrialization and urbanization. The increase in pollution and natural gas emission is also creating fluctuations in temperature in two locations.Learn more about the climate here:

Approximately what percent of land is uninhabitable due to climate?
Answer:
25%
Explanation:
Some places on Earth have a climate that is unsuitable for human life. Almost one-fourth of the Earth (25%) has this kind of climate. It can either be too cold (like on the north and south pole) or too hot (like in the deserts) for people to have a normal life.
For example, the coldest recorded temperature on the Earth is on East Antarctic Plateau, where it can go up to minus 100 degrees.
Oymyakon in Siberia, Russia is the place with the coldest climate with human inhabitance, even though the temperature can reach minus 71 degrees Celsius (-96.16 Fahrenheit).
If climate changes continue at this rate, much more of the world will be affected.

How do movements and interactions of air masses cause change in the weather?
Answer:
At a cold front, air can be forced upward quickly. Within an air mass, uneven heating can produce convection and thunderstorms. Thunderstorms get their energy from humid air. When warm, humid air near the ground moves vertically into cooler air above, the rising air, or updraft, can build a thunderstorm quickly.
