How Earth Is Like Spaceships
How earth is like spaceships
Introduction
Earth is very similar to a space ship because both are self-contained system with all the necessities to support lifelike a spaceship planet Earth moves through space, revolving around the sun at a speed of 108,000 km/hr planet earth is isolated. A spaceship has a unique life support system providing air, water, food, shelter and companionship. Earth also has its own life support system which includes the atmosphere, hydrosphere, lithosphere and biosphere.
Air & Protection
Both the earth and spaceships provide air and shelter by themselves. The atmosphere is the layer of gases that surround the Earth roughly 1000km thick. The atmosphere provides the air that we breathe and protects us from harmful UV radiation some ultraviolet radiation still gets through, but we protect ourselves by covering up, limiting our time in the Sun, and using sunscreen. In a spaceship Astronauts live and work above Earth's atmosphere, so they are exposed to very dangerous levels of ultraviolet radiation they so the spaceship system like earth protects astronauts from UV rays. The spacecraft has special shielding and there are special suits for working outside of the spaceship, there’s also special visors to protect their eyes however just like with the atmosphere high energy radiation can still pass through the shielding so Astronauts wear dosimeters instruments that monitor how much radiation each of them has received. If they reach a certain level, they do not continue to work in space. The spaceship also provides air for the astronauts to breathe replicating conditions on earth using oxygen and nitrogen. Both the earth and spaceships provide air and shelter by themselves.
Water
Both earth and spaceships provide water for the sustainability of life. The hydrosphere is the combined mass of water found on/under/over the surface of the Earth. The hydrosphere provides water for drinking, cooking, cleaning and irrigation. It’s the water cycle,
