This creates a durable protective layer between the wood and the the elements. With a vinyl swing set you can enjoy many of the features of a wood swing set without ever having to re-stain it.
â¢ Winds blow from areas of high pressure to areas of low pressure. â¢ Pressure belts are caused by the uneven heating of Earthâs surface by the sun. â¢ The Coriolis effect causes wind to appear to curve as it moves across Earthâs. surface. â¢ Global winds include the polar easterlies, the westerlies, and the trade winds.
Once absorbed, the energy is sent back into the. atmosphere in the form of infra-red rays. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our globe (earth) to warm up. This warming is what we call Global Warming, and it is caused by the greenhouse effect. The greenhouse effect is important. Without the greenhouse effect, the earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the earth warmer than usual.
