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.
The innermost layer, the troposphere, contains most of the planet's weather and extends out to 10â15km above the surface. The next layer out, the stratosphere, is drier and less dense and extends out to about 50km. The Sun's UV light breaks down oxygen in the stratosphere to form the Earth's protective ozone layer. The mesosphere, thermosphere, and ionosphere make up the remaining outer layers that extend out to about 100km.
