A greenhouse is a made of glass.. It has glass walls and roof... People grow vegetables,, flowers and other plants in them.. A greenhouse stays warm inside,, even during winter... During the daylight hours a greenhouse gets warmer and warmer and stays pretty warm at night too.. This is because the heat received from the sun is trapped inside the greenhouse by the

The Earth is also like a greenhouse... During the day Earth's surface warms up in the sunlight... At night,,, the surface cool's releasing the heat back into the air.. But some of the heat is trapped by gases like carbon dioxide in the atmosphere.... These gases.,, called greenhouse gases,, work like the glass walls and the roof and keep the Earth warm... This is global warming and it is making the Earth a dangerous planet

Unfortunately,, we are making the earth too hot ... We are using oil,,, gas and coal for running cars buses trains planes power Station and so on... These fuels have carbon in them.. This carbon and other gases trap the heat in the atmosphere and donot allow the earth to cool down... As a result,,, the Earth gets hotter...
