What type of cloud is Cloud C? What kind of weather might you expect when you see clouds of this type?

Answers

Cloud C is called as the cumulonimbus cloud which occurs when these towering clouds fill the sky and the thunderstorm might be approaching.

What is Cumulonimbus cloud?

A cumulonimbus cloud is defined as a dense, high vertical cloud that forms vertically from condensed water vapor in the lower troposphere that builds up and is carried by powerful buoyant air currents.

Water vapor above the lower parts of cumulonimbus becomes ice crystals, for example, ice and thunderstorms interact to form hail and lightning, respectively.

These clouds are also called thunderheads, where cumulonimbus can form singly, in clusters, or along squall lines, which can produce lightning and other dangerous severe weather, such as tornadoes, dangerous winds, and large hail.

Thus, Cloud C is called as the cumulonimbus cloud which occurs when these towering clouds fill the sky and the thunderstorm might be approaching.

List three effects that an increase in urbanization can have on air quality

Answers

Increase in urbanization will lead to increase in the number of people who are living in an urban area and it will also lead to increase in development in that area. The increase in development can come in form of construction of industries, which release large amount of waste products that pollute the air. This will lead to air pollution and reduce air quality. Development can also be in form of availability of electricity, that makes it possible for people to operate different electrical gadgets such as radio and television, which can result in noise pollution. Increase in the number of people who operate motor vehicles will also lead to increase in air pollution, which is caused by fossils fuel.

There are several effects that an increase in urbanization will have on air quality. One will be there will be more vehicles on the road. Before the city was urbanized, there were fewer vehicles and people. Another reason will be more industry pollution. When a city has been urbanized, more factories will come for the citizens to have jobs and to bring in more money. The burning of fossil fuels will also increase as the population grows. That will have a huge effect on the air quality.
