Question

In the context of climate change, the enhanced greenhouse effect refers to the process in which atmospheric gases trap and return more than

A) 50% of incoming solar radiation
B) 70% of outgoing longwave radiation
C) 30% of incoming solar radiation
D) 90% of outgoing longwave radiation

Answer 1

The enhanced greenhouse effect refers to the process in which atmospheric gases trap and return more than 30% of incoming solar radiation. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, absorb infrared radiation and radiate it back to Earth, contributing to the warming of the planet.

Step-by-step explanation:

The enhanced greenhouse effect refers to the process in which atmospheric gases trap and return more than 30% of incoming solar radiation.

Normally, the Earth absorbs the incoming solar radiation and re-emits it as infrared radiation. However, greenhouse gases in the atmosphere such as carbon dioxide and water vapor absorb some of the infrared radiation and radiate it back to Earth, which contributes to the warming of the planet. An increase in the concentration of these gases leads to enhanced greenhouse effect and higher surface temperatures.
