Question

Which describes the greenhouse effect?

-An artificial process
-A dangerous process
-A natural process
-A new process

Answer 1

a dangerous effect because co2 ans methane etc. are gases responsible for greenhouse effect which lead to global warming ,acid rain (by realising oxides of sulphur and nitrogen etc.) , exploitation and harm to ozone layer.

Answer 2

The correct answer is Natural process.

Greenhouse effect is a natural process that warms up earth’s atmosphere. Sun radiations when hit the ground are absorbed and some reflected back to the atmosphere and absorb by the greenhouse gases. These rays maintain the temperature of earth’s surface and keep it warm.

But due to excessive human activities, greenhouse effect is high and making the earth hotter.
