Answer 2

Greenhouse effect

Explanation:

• Amit noticed plants covered with green sheet. This kind of plantation is called greenhouse plantation.
• A greenhouse has a tendency to always stay warm irrespective of the temperature outside. During summers or winters , light from the sun enters the greenhouse and the heat rays are trapped.
• The air inside is warmed in a way that even when it is night and cool outside, the greenhouse tends to remain warm .
• Normally glass walls are used to construct a greenhouse because the glass walls trap the heat rays from the sun keeping the plants inside warm.
