Question
It is said, “$CO_2$ contributes to global warming.” Explain.
✓
Answer
Plants utilise $CO_2$ from the atmosphere for photosynthesis, thereby decreasing the amount of $CO_2$ in the air. Deforestation leads to an increase in the amount of $CO_2$ in the air because the number of trees which consume $CO_2$, is reduced. Human activities, thus contribute to the accumulation of $CO_2$ in the atmosphere.$CO_2$ traps heat and does not allow it to escape into space. As a result, the average temperature of the earth’s atmosphere is gradually increasing. This is called global warming. Thus, increased $CO_2$ contributes to global warming.

The substance $W$ is a fossil fuel. It occurs deep below the ground in certain areas of the earth. Another fossil fuel $X$ is found trapped above the deposits of $W$.
