Detailed explanation-1: -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-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: -The survival on earth without greenhouse gases is not possible because in absence of the greenhouse gases like CO2, water vapour, methane etc., the overall temperature of the earth will go down and it will become a frozen ball of ice.

Detailed explanation-4: -Earth’s surface warms up in the sunlight. At night, Earth’s surface cools, releasing the heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That’s what keeps our Earth a warm and cozy 59 degrees Fahrenheit, on average.

Detailed explanation-5: -Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect.
