Which best describes global warming?
Responses:
It is the day-to-day changes in temperature, precipitation, wind, and humidity.
It is the increase in Earth’s average surface temperature due to human activity.
It is the changes to Earth’s climate due to increased temperature.
It is the trapping of heat energy due to the addition of carbon dioxide in the atmosphere.
The best description for global warming is: It is the increase in Earth’s average surface temperature due to human activity.
The best description of global warming is: It is the increase in Earth's average surface temperature due to human activity.
The best description of global warming is that it is the increase in Earth's average surface temperature due to human activity. To arrive at this answer, you can generally understand the concept of global warming and the factors contributing to it.
Global warming refers to the long-term increase in Earth's average surface temperature. It is primarily caused by the greenhouse effect, which is the trapping of heat energy in the Earth's atmosphere. When certain gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), are released into the atmosphere, they act as a blanket, allowing sunlight to pass through but trapping the heat radiated back from the Earth's surface. This trapped heat leads to an overall warming trend.
While natural processes also contribute to the greenhouse effect, human activities, such as burning fossil fuels, deforestation, and industrial processes, have significantly increased the concentration of greenhouse gases in the atmosphere. This excess of greenhouse gases intensifies the greenhouse effect and accelerates global warming.
Therefore, the option "It is the increase in Earth's average surface temperature due to human activity" best describes global warming, capturing both the cause and effect of this phenomenon.
