Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer:
The correct option is that (Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming).
Explanation:
Increased human activities has caused the continuous release of many toxic and harmful substances into the environment. This has caused varying degrees of environmental pollution.
The increased demand of fossil fuels for generation of energy in industries, deforestation and even farming has lead to increase in the release of greenhouse gases to the atmosphere. Example of greenhouse gases include:
--> carbondioxide
--> methane
--> chlorofluorocarbons
--> nitrous oxide.
These are called greenhouse gases as they have the ability to absorb hear energy emitted from earth surface and reflecting it back to the earth surface. The trapping of this heat increases the earth's atmospheric temperature leading to a weather condition called GLOBAL WARMING. The effect of this weather change includes:
--> higher sea levels,
--> Extreme or severe weather such as storm, floods, drought and heat waves,
--> acidic ocean
-->higher death rates.
