Although mice, a cat's normal food, are about 70% water, and canned food about 78%, dry food is between 5%-10% water. That's why âcanned food does a much better job of keeping your cat well-hydrated,â Pierson tells WebMD. âThink of canned food as hosing down your cat's bladder several times a day.â.
The International Space Station orbits Earth in this layer. mesopauseâthe boundary between the mesosphere and the thermosphere; the coldest place on Earth. mesosphereâthe layer in which most meteors burn up after entering Earthâs atmosphere and before reaching Earthâs surface. stratopauseâthe boundary between the mesophere and the stratosphere. stratosphereâcontains the ozone layer; the layer where volcanic gases can affect the climate. tropopauseâthe boundary between the stratosphere and troposphere. troposphereâthe layer closest to Earthâs surface in which all weather occurs.
Three of the four inner planets (Venus, Earth and Mars) have atmospheres substantial enough to generate weather. All of them have impact craters and tectonic surface features as well, such as rift valleys and volcanoes. Mercury: Of the inner planets, Mercury is the closest to our Sun and the smallest of the terrestrial planets. This small planet looks very much like the Earthâs Moon and is even a similar grayish color, and it even has many deep craters and is covered by a thin layer of tiny particle silicates.
