Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the greenhouse effect?
A
The warming of a planet due to trapped radiation.
B
The cooling of Earth due to air pollution.
C
The heating of a solid, such as a rock.
Explanation: 

Detailed explanation-1: -The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.

Detailed explanation-2: -The Short Answer: The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere.

Detailed explanation-3: -Credit: NASA Jet Propulsion Laboratory. 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-4: -Solar radiation which travels to the Earth through space is absorbed, scattered or and re-emitted back to the Earth by atmospheric greenhouse gases. This study validated the relationship between greenhouse gases and solar radiation.

Detailed explanation-5: -Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet’s average temperature.
