Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which icon represents the mechanism that affects Earth’s temperatures, and that now is causing the temperatures to increase?
A
Specialized scientists removing carbon dioxide from the atmosphere.
B
Greenhouse effect
C
Using eco-friendly technology.
D
All of the above.
Explanation: 

Detailed explanation-1: -Mechanism of the Greenhouse Effect The incoming solar energy from the sun is redirected back towards space by the atmosphere and clouds and then some of the solar energy gets absorbed by the atmosphere and clouds. And the remaining energy gets absorbed by the Earth’s surface making it warm.

Detailed explanation-2: -Greenhouse gases in the atmosphere including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor, absorb this infrared radiation and keep it from passing into space. This energy is then reradiated in all directions, and the energy that is directed back toward the Earth warms the planet.

Detailed explanation-3: -Earth’s greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which are all natural compounds), and fluorinated gases (which are synthetic or man-made).

Detailed explanation-4: -Carbon dioxide and water vapour absorb infrared radiations coming to the earth and partly reflect it back to the earth’s surface. Due to this, the surface of the earth gets heated up. This phenomenon is called the greenhouse effect.
