Answer 2

Answer:

Greenhouse Effect

Explanation:

The type of plantation where the plants are covered with green sheets is known as a greenhouse plantation.

The green sheet is used to trap the sunlight inside and produce a heating effect. The greenhouse has the tendency to stay warm irrespective of the outside temperature.

The greenhouse provides the optimum temperature for the plants to grow and survive in colder conditions and does not let the outside temperature affect their growth.

Many ways can be opted to trap the heat inside the greenhouse apart from the use of plastics. The walls of the greenhouse can be made of glass so that the heat can be trapped inside it to provide a warm condition.
