What are 3 affect of the greenhouse effect?

Answer 1

The greenhouse effect is the process of thermal radiation from a planet's surface being absorbed by atmospheric greenhouse gases. Water vapor and carbon dioxide are the most important greenhouse gases, with methane, nitrous oxide and the ozone contributing. Clouds also have an impact on the greenhouse effect due to them absorbing infrared radiation and blocking solar radiation.

Answer 2

Three effects of the Natural Greenhouse Effect:

1. Keeps the earth comfortably warm enough for life.
2. This has been going on for millions of years.
3. Human, animal and plant life can survive and thrive.

Three effects of the Accelerated Greenhouse Effect:

1. The Green House Effect has the potential to increase the global temperature year by year. This means, it would be practically impossible for life to stay on earth for long.
2. Rise in global temperature would lead to melting of polar ice caps. This may result in rise in water level in seas and oceans. Coastal wetlands would submerge in water bodies. A warmer climate would speed up the process of evaporation and cause more rainfall.
3. Tropical cyclones will become more intensive and their ferocity will increase. Green house effect sweeps changes in biosphere.

Answer 3

Heat (infrared light) from the warmed earth rises in the atmosphere where it is trapped by greenhouse gases. These gases become warm, and they warm the air around them. Some of this heat goes back down to earth, where it warms the earth more.

Some greenhouse gases occur naturally. Water vapour and carbon dioxide move in and out of the atmosphere as part of the water and carbon cycles. Methane is emitted by rotting vegetation and animals. The greenhouse effect from natural causes is good for us, as it keeps the earth warm enough for life.

Some greenhouse gases are produced by human activity.

1. Burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, releases extra carbon dioxide (CO2) that has been hidden away for millions of years under the earth.
2. Deforestation, cutting down millions of trees that used to remove carbon dioxide from the air.
3. Agricultural practices like rice paddy farming, raising beef and dairy cattle, and pig farming, all of which release methane, another powerful greenhouse gas.

The greenhouse effect caused by human activity is called the enhanced greenhouse effect. This is dangerous for us and for the earth as it is the cause of global warming.
