Often asked: What Is The Greenhouse Affect?

What is the greenhouse effect short answer?

The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

What is the greenhouse effect and what causes it?

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 greenhouse effect Class 9?

“Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.”

Why it is called greenhouse effect?

In short: it is the natural process that warms the Earth’s surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse.

What is the main cause of greenhouse gases?

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.

What are the advantages of greenhouse effect?

Greenhouse gases keep our planet liveable by holding onto some of Earth’s heat energy so that it does not all escape into space. This heat-trapping is known as the greenhouse effect. The greenhouse effect helps to maintain a certain temperature level on Earth’s surface, making it habitable for living beings.

What are the 10 causes of global warming?

The Top 10 Causes of Global Warming

  • Power Plants. Forty percent of U.S. carbon dioxide emissions stem from electricity production.
  • Transportation.
  • Farming.
  • Deforestation.
  • Fertilizers.
  • Oil Drilling.
  • Natural Gas Drilling.
  • Permafrost.

How human can reduce the level of greenhouse gases?

Using public transportation, carpooling, biking, and walking, leads to fewer vehicles on the road and less greenhouse gases in the atmosphere. Cities and towns can make it easier for people to lower greenhouse gas emissions by adding bus routes, bike paths, and sidewalks.

Which is not a greenhouse gas?

The various greenhouse gases are carbon dioxide, methane, chlorofluorocarbon, ozone, nitrous oxide, and water vapor. Hence the gas which is not a greenhouse gas is nitrogen and the correct answer for the given question is option d).

How do greenhouse gases cause global warming?

A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.

What is meant by greenhouse gas?

Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere.

What do you mean by greenhouse?

A greenhouse is a building with glass walls and a glass roof. Greenhouses are used to grow plants, such as tomatoes and tropical flowers. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases.

What is the property of greenhouse gases?

greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.

Which gas is used in greenhouse?

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities.

Who invented greenhouse effect?

Irish physicist John Tyndall is commonly credited with discovering the greenhouse effect, which underpins the science of climate change. Starting in 1859, he published a series of studies on the way greenhouse gases including carbon dioxide trapped heat in the Earth’s atmosphere.
