Often asked: What Are Greenhouse Effect?

What is greenhouse effect explain?

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 greenhouse effect and its causes?

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. Greenhouse Effect On Earth.

What are the 4 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).

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.”

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 two causes of greenhouse gases?

  8. Empower women.

What is the cause of greenhouse effect rays?

-The greenhouse gases present in the atmosphere absorb more of the infrared radiations as compared to UV, X and radio waves, which are unable to escape the atmosphere and cause the temperature of the earth to rise, resulting in a greenhouse effect.

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).

Is Helium a greenhouse gas?

greenhouse effect The warming of Earth’s atmosphere due to the buildup of heat-trapping gases, such as carbon dioxide and methane. Scientists refer to these pollutants as greenhouse gases. helium An inert gas that is the lightest member of the noble gas series.

Is so2 a greenhouse gas?

While sulfur dioxide isn’t a direct greenhouse gas like carbon dioxide or methane, it is considered an indirect greenhouse gas. Sulfur dioxide is regarded as an indirect greenhouse gas because, when coupled with elemental carbon, it forms aerosols.

What are the top 10 causes of global warming?

The Top 10 Causes of Global Warming

  • Farming.
  • Deforestation.
  • Fertilizers.
  • Oil Drilling.
  • Natural Gas Drilling.
  • Permafrost.
  • Garbage. As trash breaks down in landfills, it releases methane and nitrous oxide gases.
  • Volcanic Eruption. Volcanoes expel large quantities of carbon dioxide when they erupt.

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 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.
