What is greenhouse effect introduction?

Introduction. The term ‘Greenhouse Effect’ refers to the way certain gases trap heat in the atmosphere, much as the glass in a greenhouse prevents rising warm air from escaping. In fact, Earth, 93 million miles from its energy source – the sun – would be about 32° C colder if certain atmospheric gases did not trap heat …

What is the greenhouse effect?

The greenhouse effect is a natural process that warms the Earth’s surface. The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.

What is the significance of residence time in terms of the greenhouse effect and climate change?

The impact of greenhouse gases on the enhanced greenhouse effect is determined by their residence time in the atmosphere. When atmospheric residence time is greater, the total impact of a greenhouse gas on global warming is larger.

What is greenhouse effect PPT?

1. Green house effect  Meaning: Progressive warming up of the earth surface due to high concentration of manmade carbon dioxide in the atmosphere.  Concentration of CO₂ works like a glass panel of greenhouse allowing short wave incoming solar radiation to come in but preventing the long wave heat to re-radiated out.

What are the advantages of greenhouse effect?

The greenhouse effect helps to maintain a certain temperature level on Earth’s surface, making it habitable for the living beings (humans, animals, plants and other organisms). Thanks to the greenhouse gases, the earth is warm enough to sustain life.

What are the causes and effects of greenhouse effect?

Greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.

What is the importance of greenhouse effect?

‘Greenhouse gases’ are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth’s surface into space and the Earth would have an average temperature of about -20°C.

What are some examples of greenhouse gases?
