), be de third planet from de sun den de only astronomical object dem know edey harbor life. Dis de Earth enable secof ebe water world, de only one for de Solar System insyd wey dey sustain liquid surface water. Almost all of Earth ein water dey contain for ein global ocean insyd, wey dey cover 70.8% of Earth ein crust. De 29.2% of Earth ein crust wey dey remain be land, chaw wey dey locate for de form of continental landmasses insyd within one hemisphere, Earth ein land hemisphere. Chaw of Earth ein land be sam what humid wey vegetation cover am, while large sheets of ice for Earth ein polar deserts dey retain more water dan Earth ein groundwater, lakes, rivers den atmospheric water dem combine. Earth ein crust dey consist of slowly tectonic plates wey dey move, wey dey interact make e produce mountain ranges, volcanoes, den earthquakes. Earth get liquid outer core wey dey generate magnetosphere wey be capable make edey deflect chaw of de destructive solar winds den cosmic radiation.
