carbondioxide and methane are examples of greenhouse gases. carbon dioxide is released from plants and animals during respiration and methane is released naturally and from cows burps
increased concentration of greenhouse gases means more radiation is absorbed, trapping the heat closer to earth - increasing temperature of the earth = greenhouseeffect
greenhouse effect is important because without it the earth would be very cold and stuck in the Ice Age
the greenhouse effect has caused global temperatures and precipitation to increase due to factors like solar insulation. precipitation is increasing in the Americas but reducing in Africa
photosynthesis is important in regulating carbonlevels in the atmosphere as organisms absorb sunlight and use it as energy to convert carbondioxide
oceans photosynthesis is regulated by phytoplankton, and thrive in shallow, nutrient rich cold water
terrestrial photosynthesis is regulated by plants and thrives in dense vegetation like tropical rainforests
soil health is its ability to sustain plant and animal life effectively
organic matter influences soil health and its ability to provide for organisms and plant life because organic matter holds a lot of carbon, increasing soil fertility and moisture storage, allowing water to infiltrate into roots of plants
fossil fuel combustion has increased due to the increase in population and the increase in industrialisation (Industrial Revolution in UK in 18th century)
fossil fuels contain high amounts of carbon and when they combust chemical bonds releases heat energy, meaning concentrations of greenhousegasesrise at a faster rate to carbon sequestration adding to enhanced greenhouse effect
increased greenhouse gases leads to globalwarming which leads to implications for:
climate - wet areas get wetter, dry areas get drier
