Question

Write a short note on global warming.
Name one gas which causes a greenhouse effect. What are the harmful consequences of this effect?

Answer 1

The greenhouse impact is brought about by the climatic amassing of gases like carbon dioxide and methane, which contain a portion of the warmth radiated from Earth's surface. The air permits the majority of the apparent light from the Sun to go through and arrive at Earth's surface.

Complete answer:
We have to know that the greenhouse impact accepted its name on the grounds that the world's air acts similar to the glass or plastic rooftop and dividers of a nursery. Daylight enters a nursery through the straightforward rooftop and warms the plants yet the warmth is discharged by the plants as infrared radiation can't go through the rooftop and dividers. Subsequently the temperature inside the house increases. An impact like the nursery is answerable for keeping the world's surface hotter. The climate around the earth behaves like a glass of the nursery chamber. This is known as Greenhouse impact.
A large portion of the radiation transmitted by earth lies in the infrared district. Practically $84\%$ of the warmth transmitted by the earth is consumed by the gases in the climate, and re-emanated back to the earth’s surface. This expands the worldwide temperature. This is known as Global warming.
The gases present in the atmosphere which are responsible for global warming are carbon dioxide, water vapour, oxides of nitrogen, methane, ozone, chlorofluorocarbons, etc.
Carbon dioxide causes a greenhouse effect.
Harmful consequences of the greenhouse effect are:
Rise in sea level - Higher sea level would increase the frequency and severity of floods, damage coastal areas, i.e., low lying areas would submerge and cause loss of soil replenishment.
Changing patterns of rainfall - Patterns of rainfall would change worldwide causing large shifts in agriculturally productive areas.
Evaporation of water from aquatic systems: Global warming will cause more water to evaporate from aquatic systems and increase the concentration of water vapour in the atmosphere. The extra water vapour will amplify warming because water vapour itself is a greenhouse gas.

Note:
The green house can give climate control to high esteem crops like restorative plants, blossoms and so forth. Crops inside a nursery are solid and give better outcomes. The plan of a nursery relies on the scope of the spot and the necessity of yield.
