Question: What Is Green House?

What is Greenhouse and its effects?

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 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 major causes of greenhouse effect?

Burning fossil fuels produces huge quantities of carbon dioxide (CO2) which is a greenhouse gas. Carbon dioxide along with other greenhouse gasses such as methane, nitrous oxide and chlorofluorocarbons (CFCs) are changing the composition of the atmosphere and are adding to the greenhouse effect.

Why is the greenhouse effect harmful?

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

Which gas is used in greenhouse?

How does a green house work?

A greenhouse works by converting light energy into heat energy. Light rays from the sun enter the greenhouse, where they are absorbed by plants and objects and converted to heat. Greenhouses can get too hot, which is why many have windows, vents or fans to help release hot air as needed.

Is it worth having a greenhouse?

You don’t need a greenhouse to grow your own fruit and veg, but it certainly helps. Having a greenhouse allows you to grow more crops for longer. You’ll be able to start fruit and veg off earlier in the season and extend harvest time with longer cropping.

Do plastic greenhouses work?
