The greenhouse effect is primarily caused by greenhouse gases in the atmosphere, which contribute to the warming of the Earth. The correct explanation of how greenhouse gases function is:
Greenhouse gases absorb the sun’s energy slowing or preventing heat from escaping into space.
Here’s a more detailed breakdown of the process:
-
Solar Radiation: The sun emits energy in the form of sunlight, which passes through the Earth's atmosphere and reaches the surface.
-
Absorption and Re-radiation: The Earth absorbs some of this energy, which warms the surface. The Earth then re-radiates some of this energy back into the atmosphere as infrared radiation (heat).
-
Greenhouse Gas Interaction: Greenhouse gases (such as carbon dioxide, methane, and water vapor) in the atmosphere absorb some of the infrared radiation emitted by the Earth.
-
Retaining Heat: Instead of allowing all of this heat to escape into space, greenhouse gases trap some of it, effectively warming the atmosphere.
-
Resulting Temperature Increase: This process helps to maintain the Earth's temperature at a level suitable for life but, when excessive greenhouse gases accumulate, it can lead to an overall increase in global temperatures, commonly referred to as global warming.
The options provided in your question include some inaccuracies; greenhouse gases do not reflect sunlight in a way that would create significant warming or directly warm the oceans or cause dramatic weather on their own—but their effects extend to influencing weather patterns and ocean temperatures as a consequence of climate change.
