What is greenhouse example?
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The absorbed energy warms the atmosphere and the surface of the Earth.
What are uses of greenhouse?
Greenhouse, also called glasshouse, building designed for the protection of tender or out-of-season plants against excessive cold or heat. In the 17th century, greenhouses were ordinary brick or timber shelters with a normal proportion of window space and some means of heating.
What is greenhouse in simple words?
A greenhouse, or simply green house (also called a glass-house or hothouse) is a building where plants such as flowers and vegetables are grown. Greenhouses warm up during the day via penetration of the sun’s rays which heat the plants, soil and structure. This heat is given up gradually throughout the night.
What is a greenhouse Class 6?
A greenhouse is a house made of glass that can be used to grow plants. The sun’s radiations warm the plants and the air inside the greenhouse. The heat trapped inside can’t escape out and warms the greenhouse which is essential for the growth of the plants. During the day the sun heats up the earth’s atmosphere.
Why it is called greenhouse?
Greenhouses were originally referred to as botanical gardens. This is because the same process that warms up the earth also takes place in a greenhouse, where the glass structure will capture the sunlight and the area under the glass will heat up. …
Why is it called greenhouse gas?
Greenhouse gases (GHG) include carbon dioxide, water vapor, methane, ozone, nitrous oxide and fluorinated gases. These molecules in our atmosphere are called greenhouse gases because they absorb heat. Thus, greenhouse gases trap heat within the surface-troposphere system.
What are the disadvantages of greenhouse?
The Disadvantages of a Greenhouse:
- Can be expensive to build.
- Can be expensive to heat.
- Requires constant monitoring, maintenance and care.
- Could increase electrical and water bills.
- May detract from aesthetic appeal of a garden.
What are the 5 advantages of greenhouse gases?
The greenhouse gases help block the harmful solar radiation from reaching planet’s surface. These gases work like a filter and bounce back most of the unwanted and damaging energy into space. Ozone, which is one of the crucial greenhouse gases, absorbs the harmful ultra-violet (UV) rays of the sun.
What is the best definition of greenhouse?
The definition of a greenhouse is a building made of glass panes in which heat and humidity can be regulated in order to grow plants. A building made mainly of glass, in which the temperature and humidity can be regulated for the cultivation of delicate or out-of-season plants.
What type of word is greenhouse?
noun, plural green·hous·es [green-hou-ziz]. a building, room, or area, usually chiefly of glass, in which the temperature is maintained within a desired range, used for cultivating tender plants or growing plants out of season.
How do you explain greenhouse to a child?
A greenhouse is a building with glass walls and a glass roof. Greenhouses are used to grow plants, such as tomatoes and tropical flowers. A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside.
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.
