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.

EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous

The Good Earth Style Pearl Buck’s style in The Good Earth has been compared to old Chinese novels. Actually‚ it is a simple‚ direct narrative style.

The length of the day would be different‚ the origins of life on Earth would be slowed‚ and the biological evolution of life on Earth would vary greatly.

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

Earth Day Some people who talk about the environment talk about it as though it involved only a question of clean air and clean water. The environment involves the whole broad spectrum of man’s relationship to all other living creatures‚ including other human beings. It involves the environment in its broadest and deepest sense.
