Which Statement Best Descrivbes the Green House Effect
The greenhouse issue is the style in which rut is trapped shut to Earth's surface by "greenhouse gases." These rut-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than information technology would be without them. Greenhouse gases include carbon dioxide, methane, nitrous oxides, and h2o vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a "feedback.") Scientists take adamant that carbon dioxide's warming effect helps stabilize Earth's atmosphere. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, World's surface would exist some 33°C (59°F) cooler.
Greenhouse gases occur naturally and are role of our temper'due south makeup. For that reason, Globe is sometimes called the "Goldilocks" planet – its weather condition are not as well hot and not too cold, only simply right to allow life (including us) to flourish. Function of what makes Earth so amenable is its natural greenhouse consequence, which keeps the planet at a friendly 15 °C (59 °F) on average. Just in the last century or so, humans have been interfering with the planet'due south energy balance, mainly through the burning of fossil fuels that add carbon dioxide to the air. The level of carbon dioxide in Globe's atmosphere has been rising consistently for decades and traps extra heat nearly Earth'south surface, causing temperatures to rise.
