Question

_______________warming is due to accumulation of greenhouse gases.

Answer 1

Global warming:

• Sun's radiation has higher energy when these radiations reach the earth's surface.
• Some of the energy is radiated in the form of heat and the rest is reflected back into the space.
• Greenhouse gases like carbon dioxide (${\mathrm{CO}}_2$), water vapours, and methane (${\mathrm{CH}}_4$) gases absorb this heat and prevent it from escaping, thus keeping the earth's atmosphere warm.
• The process in which temperature rises on the earth's surface due to greenhouse gases is known as global warming.

Therefore, global warming is due to the accumulation of greenhouse gases.
