The atmospheric layer, stretching 17-48 (11-31 miles) kilometers above the earth's surface, is the stratosphere.Its lower portion contains enough ozone gas to filter out most of the sun's harmful ultraviolet radiation.This global sunscreen allows life to exist on land and in the surface layers of bodies of water.
大氣層，由地球表面延伸14-48公里(11-31英哩)是平流層。在它的更底部包含足夠的臭氧氣體足夠過濾掉太陽大部分有害的紫外線輻射。這個全球的防護罩使得生命存在在這土地上和大片在表層的水。
The hydrosphere consists of the earth's water.It is found as liquid water (on the surface and underground), ice (polar ice, icebergs, and ice in frozen soil layers called permafrost), and water vapor in the atmosphere.Most of this water is in the oceans, which cover about 71% of the globe.
水圈由地球上的水所組成。它有液態水(在地表和地下)、冰(極地的冰、冰山和在冰凍在土壤中的冰稱為永凍土)和在空氣中的水蒸氣。大部分的水都在海洋裡，它覆蓋了70%的地球。
The geosphere consists of the earth's intensely hot core, a thick mantle composed mostly of rock, and a thin outer crust. The lithosphere is the earth's solid crust and upper mantle.It contains nonrenewable fossil fuels and minerals we use as well as renewable soil chemicals that organisms need to live, grow, and reproduce.
地圈是由地球很熱的核心和是由大部分的岩石和薄薄的外表硬層所組成的地幔所組成的。
地殼是地球堅硬的的殼層和地幔的上半部。它包含了不可更新的礦物燃料和我們也是用可更新的礦物，也就是生物生存、成長和繁殖所需的土壤化學物質。
