1. Compare the natural greenhouse effect with the human-induced process.

To compare the natural greenhouse effect with the human-induced process, we first need to understand what the greenhouse effect is.

The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere trap heat from the sun and warm the planet. This natural process is essential for maintaining temperatures that can support life on Earth.

The natural greenhouse effect is primarily caused by the presence of certain gases in the atmosphere, such as carbon dioxide (CO2), methane (CH4), and water vapor. These gases absorb and re-emit infrared radiation, effectively acting as a blanket around the Earth. They allow sunlight to pass through the atmosphere but trap the heat radiation that is emitted from the Earth's surface, keeping the planet warm.

On the other hand, the human-induced greenhouse effect refers to the enhanced greenhouse effect caused by human activities, mainly the burning of fossil fuels (such as coal, oil, and natural gas) and deforestation. These activities release significant amounts of greenhouse gases, primarily carbon dioxide, into the atmosphere. As a result, the concentration of greenhouse gases has been steadily increasing since the industrial revolution.

The human-induced greenhouse effect intensifies the natural greenhouse effect, leading to a warming of the Earth's surface and the lower atmosphere. This phenomenon is commonly referred to as global warming or climate change. The increase in greenhouse gas concentrations amplifies the heat-trapping effect, causing temperatures to rise beyond what would be considered normal.

In summary, the main difference between the natural greenhouse effect and the human-induced process is the source of greenhouse gas emissions. The natural greenhouse effect is a vital natural process that helps regulate the Earth's temperature, while the human-induced greenhouse effect is the result of human activities emitting excessive amounts of greenhouse gases, leading to the warming of the planet.
