Question

The greenhouse effect which is responsible for climate change involves the warming of _______.
A) Troposphere
B) Thermosphere
C) Stratosphere
D) Ionosphere

Answer 1

Hint: The greenhouse effect is a natural phenomenon that causes the surface of the Earth to warm up. The Earth's atmosphere reflects some sunlight back to space, while gases absorb and re-radiate the rest. Water vapour, carbon dioxide, nitrous oxide, methane, ozone, and several other man-made substances like chlorofluorocarbons are examples of greenhouse gases (CFCs).

Complete answer:
The natural greenhouse effect is created by greenhouse gases, which are basically invisible to solar radiation but absorb a significant amount of the infrared radiation emitted by the Earth. The Earth warms by roughly 30°C as a result, making it habitable. Human activities have resulted in gradually growing amounts of greenhouse gases—carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons—in the atmosphere since industrialization, raising concerns about the so-called "enhanced greenhouse effect."

The greenhouse effect occurs when the sun's heat is trapped in the earth's atmosphere as a result of increased air pollution. The warming of the troposphere, the earth's innermost layer, causes climate change.

Therefore the correct answer is option ‘A’.

Note: The current rise in the average temperature of Earth's air and oceans is referred to as global warming. The most recent example of climate change is often referred to as global warming. The climate of the Earth has shifted several times. Multiple ice ages have occurred on our globe, during which ice sheets and glaciers covered huge areas of the planet. It has also seen hot periods with temperatures higher than they are now.
