The greenhouse effect is a warming of Earth's surface and the air above it. It is caused by gases in the air that trap energy from the Sun. These heat-trapping gases are called greenhouse gases. The most common greenhouse gases are water vapor, carbon dioxide, and methane.
What is greenhouse effect for Class 8?
Solution: Greenhouse effect is a process by which solar radiation is absorbed by greenhouse gases and the temperature of Earth's atmosphere is increased. This increase in the temperature of the surroundings is responsible for global warmingglobal warmingIn 1896 Svante Arrhenius calculated the effect of a doubling atmospheric carbon dioxide to be an increase in surface temperatures of 5–6 degrees Celsius. This 1902 article attributes to Svante Arrhenius a theory that coal combustion could eventually lead to human extinction.https://en.wikipedia.org › History_of_climate_change_scienceHistory of climate change science - Wikipedia. Gases like Carbon dioxide, methane, nitrous oxide, water vapour, etc.
What is the greenhouse effect Class 4?
The Short Answer: The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.Oct 19, 2021
What are the top 3 sources of greenhouse gas emissions?
What 3 greenhouse gases are created by human activities?
- Carbon dioxide (CO2). Accounts for around three-quarters of the warming impact of current human greenhouse-gas emissions. ...
- Methane (CH4). ...
- Nitrous oxide (N2O). ...
- Fluorinated gases ("F gases").
What are the 5 most important gases causing the greenhouse effect?
The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which all occur naturally), and fluorinated gases (which are synthetic). Greenhouse gases have different chemical properties and are removed from the atmosphere, over time, by different processes.Jul 16, 2019
