This process keeps Earth’s temperature suitable for life.
A
Convection Currents
B
Greenhouse Effect
C
Albedo Effect
D
Water Cycle
Explanation: 

Detailed explanation-1: -’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-2: -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: -Earth’s atmosphere keeps much of the Sun’s energy from escaping into space. This process, called the greenhouse effect, keeps the planet warm enough for life to exist.

Detailed explanation-4: -The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.

Detailed explanation-5: -Some atmospheric gases absorb and re-emit infrared energy from the atmosphere down to the Earth’s surface. This process, the greenhouse effect, leads to a mean surface temperature that is 33 °C greater than it would be in its absence.
