role of carbon dioxide gas in increasing the average temperature of earth.

Answers
Answer:
Carbon dioxide is a greenhouse gas
Explanation:
Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.
Answer:
carbon-dioxide is heavy gas. when plastics and other things made of polymer is burnt it produces CO2. Due to accumulation of CO2 it make a layer in the earth's atmosphere. when sun rays strike with earth, some is absorbed by earth and others are reflected and goes back but CO2 reflect it again towards the earth. due to which there is increase in temperature of earth.
