Which of the following is TRUE regarding the greenhouse effect? increased levels of human-produced carbon dioxide have enhanced the greenhouse effect the greenhouse effect did not exist before humans "greenhouse gases work by magnifying incoming solar radiation onto Earth's surface, just like in a greenhouse" volcanoes are the largest source of greenhouse gases all of the above are true regarding the greenhouse effect

Answers

Answer 1

Answer:

- increased levels of human-produced carbon dioxide have enhanced the greenhouse effect

- volcanoes are the largest source of greenhouse gases

Explanation:

The greenhouse effect is cause by the presence of greenhouse gases in the atmosphere, such as the carbon dioxide and methane. These gases have the ability to trap the heat into the Earth's atmosphere in much greater percentage, resulting in warming up of the atmosphere, thus the global climate as well. The biggest source of these gases are the volcanoes, being responsible for pretty much all of the greenhouse gases in the atmosphere for most of the geological history of the Earth. Despite still being number one, the volcanoes get assisted by the human activity in the past two centuries when it comes to greenhouse emissions into the atmosphere. By using the fossil fuels to produce energy, which means burning them, the humans have constantly been increasing their contribution in the amount of greenhouse gases released into the atmosphere. If that trend continues with this tempo, we might experience more dramatic climate change in the near future which can have been consequences.

Answer 2

The true statement regarding the greenhouse effect is that increased levels of human-produced carbon dioxide have enhanced the greenhouse effect. Therefore, option A is correct.

The greenhouse effect refers to the process in which certain gases in the Earth's atmosphere trap and re-emit heat, leading to the warming of the planet. It works by allowing sunlight to pass through the atmosphere but trapping the heat radiated back from the Earth's surface.

This natural phenomenon is essential for maintaining a livable temperature on Earth. However, human activities, such as the burning of fossil fuels, have increased the concentration of greenhouse gases, such as carbon dioxide, intensifying the greenhouse effect and contributing to global warming.
