1 What are the definitions of the following terms?
3) greenhouse: is a structure with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible solar radiation from the sun is absorbed by plants, soil, and other things inside the building. 4) methane: is the simplest alkane, the main component of natural gas, and probably the most abundant organic compound on earth. The relative abundance of methane makes it an attractive fuel.

4 What are the potential effects of global warming? The effects of global warming may be physical, ecological, social or economic. Evidence of observed climate change includes the instrumental temperature record, an increase of extreme weather events (such as hurricanes, earthquakes, volcanoes, and landslides), rising sea levels, decreased snow cover in the Northern Hemisphere, mass animal extinctions and human migrations.
2 What is the relationship between carbon dioxide, greenhouse gases and the thinning ozone layer with global warming? Carbon dioxide is a greenhouse gas. Burning oil, coal and fossil fuels leads to a sharp increase in the greenhouse gas which build up and condense, forming a thick gas layer of carbon dioxide. This gas traps heat from the sun and destroys the ozone layer, the layer which protects the Earth from harmful radiation, causing global warming.
