Answer 1

The topic discusses about greenhouse effect and Global warming

Explanation:

• The same amount of energy returns to space when energy from the Sun falls on earth, but few amounts of energy are trapped by the atmosphere. The world is warm and the most important thing that the atmosphere is doing is keeping us warm. The trapping of energy is called greenhouse effect
• But this cycle of cooling and warming has happened quickly since the 19th century. These rapid changes can result in disastrous events. The rise in warming is mostly due to the increase in industry, the heating events increase by the smoke and gas emitted from these factories. The current trend of global warming is therefore also known as global warming (human-caused).
