Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Paragraph On Global Warming: Global warming is the rise of average global temperature on the surface of the earth. It has been recognized as a severe threat to the environment since the 1950s. The rate of increase in global temperatures sees accelerated growth for the last 5 decades. Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. “Global warming” refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere. “Climate change” refers to the increasing changes in the measures of climate over a long period of time – including precipitation, temperature, and wind patterns. Global Warming is important since it helps determine future climate expectations. Through the use of latitude, one can determine the likelihood of snow and hail reaching the surface. ... Global warming is the unequivocal and continuing rise in the average temperature of Earth's climate system. The biggest causes of global warming are deforestation, factories, electricity wastage, etc. Deforestation reduces the number of trees, which means there will be more carbon dioxide in the air. Factories produce a lot of greenhouse gases, and most electricity requires burning fossil fuels. Global warming is the term used to describe the rising of the average temperature on Earth. It has to do with the overall climate of the Earth rather than the weather on any given day. History of Global Temperatures. The Earth has gone through changes in temperature before.
