Electricity generated from fossil fuels such as coal and crude oil to run the industries leads to high concentrations of harmful gases in the atmosphere. This causes ozone layer depletion and global warming. What do coal and oil have in it that releases as oxides into the atmosphere?

Solution

The correct option is C Sulphur
Sulphur combines to form sulphur dioxide in the air. 99% of the sulphur dioxide comes from human activities. Sulphur dioxide affects human beings, it causes irritation in the nose, coughing, wheezing and a tight feeling in the chest. Sulphur is present in coal and oil and sulphur dioxide is repsonsible for ozone layer depletion and global warming.

Q. According to research done by environmental scientists, releases of huge quantities of greenhouse gases such as carbon dioxide is causing ozone depletion in the upper atmosphere. Due to ozone depletion, harmful rays will be able to enter the earth’s environment and this could cause serious immunodeficiency disorders in most mammals. Which of the following statements has been assumed to support the above argument?

Q. Assertion (A) : Ozone depletion leads to global warming.
Reason (R) : UV rays cause destruction of the ozone layer.

Q. Statement 1: Crude oil and coal are examples of fossil fuel.
Statement 2: Crude oil is formed as a result of the decomposition of dead sea organisms.

What depletes the ozone layer in the atmosphere? What are the harmful effects of the depletion of the ozone layer on us?

We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year, which are brewing a disastrous stew. The greatest consequences of the atmosphere crisis may be global warming and ozone depletion. The Earth appears to be warming due to the greenhouse effect. Scientists estimate that average temperature could climb about 20C in 20 years.Global warming is the predicted result of the greenhouse effect, created by the greenhouse gasses, such as carbon dioxide and methane, in the atmosphere. This change in the global climate would have disastrous results including drought, coastal flooding and increased species extinction. Also, the scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the Sun. Once the ozone layer is completely destroyed, all life on the Earth will cease to exist, killed by the deadly radiation. The planet will become a barren rock devoid of all life. And when this happens the process of industrialisation would have to take the blame, which has resulted in increased use of fossil fuels such as coal, petroleum and diesel.
