The Earth and Venus are near each other in the Solar System, and are similar in size, density, and composition. Based on our understanding of the origin of the Solar System, we would expect that their initial atmospheres would have been rather similar. Yet the present atmospheres of the two planets could hardly be much more different than they are. How did this come to be? The reason is thought to lie in what is termed the “Run Read more…

The main reason for deforestation is the demand for fuel, wood and paper products, cattle ranching, farming, mining and road construction. Half of all the trees cut down in the world are used for fuel. Burning wood is common in developing countries where there are often no readily-available alternatives. This in itself may not a huge problem; only, most of these trees are not replaced, which is a problem. The use of wood and paper Read more…

Wind energy is a converted form of solar energy. The sun’s radiation heats different parts of the earth at different rates—most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect at different rates. This in turn causes portions of the atmosphere to warm differently. Hot air rises, reducing the atmospheric pressure at the earth’s surface, and cooler air is drawn i Read more…
