Green house gases such as CO2, ozone, methane, the chlorofluoro carbon compounds and water vapour form a thick cover around the earth which prevents the IR rays emitted by the earth to escape. It gradually leads to increase in temperature of atmosphere.

The Greenhouse Effect:
The greenhouse effect is a natural process that occurs in the Earth's atmosphere, which helps to keep the planet warm. It is caused by various gases present in the atmosphere that trap heat, preventing it from escaping into space. This process is essential for life on Earth, as without it, the planet would be too cold to support life.
Explanation of Answer:
The correct answer is option 'A' - the presence of gases, which in general are strong infrared absorbers, in the atmosphere.
The greenhouse effect is caused by a group of gases known as greenhouse gases, which include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O). These gases are present in the Earth's atmosphere and act like a blanket, trapping heat from the sun and preventing it from escaping into space. This causes the Earth's temperature to rise, leading to global warming.
Of these gases, carbon dioxide is the most significant contributor to the greenhouse effect, as it is released into the atmosphere through human activities such as burning fossil fuels and deforestation. Methane is also a potent greenhouse gas, but its concentration in the atmosphere is much lower than that of carbon dioxide.
Conclusion:
In conclusion, the greenhouse effect is caused by the presence of greenhouse gases in the Earth's atmosphere, which trap heat and prevent it from escaping into space. This process is essential for life on Earth, but human activities such as burning fossil fuels are increasing the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.

The greenhouse effect occurs when certain gases in the Earth's atmosphere (the air around the Earth) trap infrared radiation. This makes the planet become warmer, similar to the way it makes a greenhouse become warmer.

The greenhouse effect is caused by greenhouse gases; the most important greenhouse gases in Earth's atmosphere are: water vapor, carbon dioxide(CO2), and methane. When there is more greenhouse gas in the air, the air holds more heat. This is why more greenhouse gases cause climate change and global warming.
The greenhouse effect is natural. It is important for life on Earth. Without the greenhouse effect, the Earth's average temperature would be around -18 or -19 degrees Celsius (0 or 1 degree Fahrenheit). Earth would be locked in an ice age. Because of the greenhouse effect, the Earth's actual average temperature is 14 degrees Celsius (57 degrees Fahrenheit).
