Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The Earth acts like a greenhouse that catches and traps heat from the sun.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The greenhouse effect is the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.

Detailed explanation-2: -The Greenhouse Effect Greenhouse gases let the sun’s light shine onto Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable.

Detailed explanation-3: -’Greenhouse gases’ are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth’s surface into space and the Earth would have an average temperature of about-20°C.

Detailed explanation-4: -A real greenhouse traps heat because its glass stops the warm air inside from transferring heat to the colder surrounding air. Greenhouse gases don’t stop heat transfer in this way, but as this piece explains, in the end they have a similar effect on the Earth’s temperature.

Detailed explanation-5: -The gas in the atmosphere which traps the heat rays reflected by the earth is called Carbon Dioxide.
