medhrk. The greenhouse effect is caused by the burning of fossil fuels and deforestation-is true. The burning fossil fuels leads to emission of CO2 in the air which is green house gas. deforestation makes the number of CO2 consumer less in quantity so increase CO2 level.
Some of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2). Human activity--such as burning fossil fuels--causes more greenhouse gases to build up in the atmosphere. As the atmosphere thickens with more greenhouse gases, more heat is held in.Fossil fuels such as oil, coal and natural gas are high in carbon and, when burned, produce major amounts of carbon dioxide or CO2.ome of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2).
