The correct answer is: B. Carbon dioxide
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing the planet to warm. The main source of human-caused carbon dioxide emissions is from burning fossil fuels for electricity, heat, and transportation. Other sources include deforestation, agriculture, and industrial processes.
Carbon monoxide is a poisonous gas that is not a
greenhouse gas. It is produced when fossil fuels are burned incompletely. Nitrous oxide is a greenhouse gas that is produced by agriculture, fossil fuel combustion, and industrial processes. Sulphur dioxide is a greenhouse gas that is produced by burning fossil fuels.The greenhouse effect is a natural process that helps to keep the Earth’s climate stable. However, human activities are increasing the levels of greenhouse gases in the atmosphere, which is causing the planet to warm at an unprecedented rate. This warming is causing a number of changes to the Earth’s climate, including rising sea levels, more extreme weather events, and changes in plant and animal life.
It is important to reduce our emissions of greenhouse gases in order to mitigate the effects of climate change. We can do this by switching to renewable energy sources, improving energy efficiency, and reducing our reliance on fossil fuels.
