The Silestone countertop I purchased is actually a composite of natural and man-made materials as opposed to granite which is strictly a natural stone product.
A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. The greenhouse effect occurs as the gases reach Earthâs surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere.
During the month of July the land-crowded northern half of our planet is tilted toward the Sun. Earth's temperature is slightly higher in July because the Sun is shining down on all that land, which heats up rather easily, says Spencer. Physicists would say that continents have low heat capacity.
