thick that accounts for the bulk of the Earth. The crust is primarily made of granite and basalt while the mantle beneath is made of peridotite. More about all that below. How We Know the Earth Has a Crust Just a century ago‚ we didn’t know the Earth has a crust. Until the 1900s all we knew was that our planet wobbles in relation to the sky as if it had a large‚ dense core. Astronomical observations told us so.

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen
