Question: Write a paragraph in about 120 words on ‘Greenhouse Effect‘ by answering the questions below.

  1. What is the greenhouse effect?
  2. What are the causes of the greenhouse effect?
  3. What will happen if the world’s temperature keeps on rising?
  4. What is the threat to Bangladesh?
  5. How can this problem be solved?

Answer: In cold countries, green plants and vegetables are grown in glass houses where sun-rays necessary for trees are trapped. As a result, cold air cannot harm them. But the heat trapped in this system cannot go out of this earth. For this reason, our atmosphere which is guarded by an ozone layer cannot resist the entrance of ultraviolet rays from the sun. This causes the increase of temperature in the atmosphere which has an adverse effect. This is called the greenhouse effect. The main effect of the greenhouse is the increase of carbon-di-oxide. With the increase of carbon dioxide, the temperature of the earth is becoming hotter day by day. So, the ice in the polar regions is melting and if this process continues for a long time the level of water in the seas will rise and thereby flood coastal areas and farmlands will go under water. The alarming news about Bangladesh is that for the rise of the sea level, the lower southern part of the country may one day go under water. So, deliberate cutting down of forests must be stopped, a tree plantation programme must be made momentous and sources of emitting carbon dioxide and carbon monoxide should be controlled.

Or,

Greenhouse Effect

Question: Answer the following questions to form a continuous paragraph. (100 words)

  1. What is the greenhouse effect?
  2. How is it caused?
  3. What is the main culprit for global warming?
  4. What are the threats of global warming?
  5. What measures can we take to prevent global warming?

Answer: The rise in atmospheric temperature is known as the greenhouse effect. The carbon dioxide is primarily responsible for temperature rise in the atmosphere. The carbon dioxide is given off when coal and oil are burnt. As a result, the ice covering the North and South poles is melting and may eventually lead to a rise in sea levels which can flood many areas of the world. Scientists have already given warning that some parts of coastal countries including Bangladesh may go under water due to the greenhouse effect. The total area of deserts is increasing every year. Many species of animals and plants are endangered with the threat of extinction. Cutting down of forests indiscriminately is the main culprit for global warming. Tree plantation program should be adopted soon. Steps should be taken to put an end to the causes and sources of emitting carbon dioxide. These are the measures we can take with a view to preventing global warming.
