THE EARTH INTERIOR CAN BE IMAGINED AS LAYER OF ONION.
DEEPEST MINE IN THE WORLD IS IN SOUTH AFRICA .
IT IS 4KM DEEP.
TO REACH AT THE CENTER OF THE EARTH WE HAVE TO DIG ABOUT 6000 KM.
THE UPPERMOST LAYER OF THE EARTH IS CALLED CRUST.
IT IS ABOUT 35 KM FROM THE CONTINENTAL PLACE AND ABOUT 5 KM FROM THE OCEAN LEVEL.
THE MAIN MINERAL CONSTITUENT OF CONTINENTAL PLACE IS ALUMINIUM AND SILICA AND HENCE CALLED SIAL.
THE OCEANIC CRUST IS MAINLY CONSTITUTE OF SILICA AND MAGNESIUM AND HENCE CALLED SIMA.
JUST BENEATH THE CRUST,MANTLE EXISTS AND IT GOES DOWN TO 2900 KM BELOW THE CRUST.
THE INNERMOST LAYER IS CALLED CORE WITH THE RADIUS OF 3500KM.
IT MAINLY CONSTITUTE NICKLE AND IRON AND HENCE CALLED NIFE.
THE CENTRAL CORE HAS HIGH PRESSURE AND HIGH TEMPERATURE.
THE RADIUS OF EARTH IS CALLED 6371 KM.
ROCK AND MINERAL:::::
THE EARTH CRUST CONSIST OF VARIOUS TYPES OF ROCK.
THE ROCK ARE CLASSIFIED AS:
SEDIMENTRY ROCK
METAMORPHIC ROCK
IGNEOUS ROCK
IGNEOUS ROCK::::
WHEN THE MOLTEN MAGMA COOL's UP ,IT FORM ROCK AND THAT ROCK IS CALLED AS IGNEOUS ROCK.
IGNEOUS ROCK IS ALSO CALLED AS PRIMARY ROCK.
THE IGNEOUS ROCK IS ALSO CALLED AS PRIMARY ROCK.
THERE ARE TWO TYPE OF IGNEOUS ROCK
1)INTRUSIVE ROCK::::SOMETIMES SOLID MAGMA COOL's DOWN IN THE EARTH CRUST AND THE ROCK SO FORMED IS CALLED AS INTRUSIVE IGNEOUS ROCK AND THEY DON't HAVE GRAINED AND THEY HAVE LARGE GRAINS.
GRANITE IS THE BEST EXAMPLE OF INTRUSIVE IGNEOUS ROCK.
2)EXTRUSIVE ROCK::::WHEN THE MOLTEN MAGMA COMES OUT OF EARTH SURFACE AND COOL's UP RAPIDLY,THE ROCK SO FORMED IS CALLED AS EXTRUSIVE ROCK.
THEY ARE HAVING A FINED GRAINED ROCK AND BASALT IS THE BEST EXAMPLE.
DECCAN PLEATEU IS MADE UP OF BASALT.
SEDIMENTRY ROCK::::
ROCK ROLL's DOWN,CUT DOWN AND ARE FORMED INTO SMALL PIECES.
THEY ARE TRANSPORTED BY WIND AND WATER.
FOR EXAMPLE::::SANDSTONE IS MADE UP OF GRAINS OF SANDS.
THESE ROCK MAY CONTAIN THE FOSSIL OF LIVING BEING THAT LIVED ONCE UPON THEM.
SEDIMENTRY ROCK MAY ALSO CONTAIN FOSSIL FUEL.
METAMORPHIC ROCK::::THE SEDIMENTRY ROCK OR IGNEOUS ROCK IS CONVERTED INTO METAMORPHIC ROCK UNDER HUGE PRESSURE AND TEMPERATURE.
FOR EXAMPLE:CLAY CHANGES INTO SLATE AND LIMESTONE CHANGES INTO THE MARBLE.
ROCK CYCLE::::ROCK CYCLE IS A TIME IN WHICH THE ROCK IS FORMED.
FOR EXAMPLE HOT MAGMA COOL UP TO FORM A IGNEOUS ROCK AND WHEN IGNEOUS ROCK IS BROKEN INTO SMALL PIECES OR SEDIMENTS,THEY ARE CONVERTED INTO SEDIMENTRY ROCK AND WHEN THE SEDIMENTRY OR IGNEOUS ROCK ARE SUBJECTED INTO HUGE PRESSURE AND HEAT,THEY ARE CALLED AS METAMORPHIC ROCK.
THE SEDIMENTRY CAN BE MADE INTO THE MOLTEN MAGMA UNDER SOME CONDITIONA AND WHEN THEY COOL UP,THEY ARE FORMED INTO THE IGNEOUS ROCK.
RED FORT IS MADE OF RED SANDSTONE AND
TAJ MAHAL IS MADE OF WHITE MARBLE.
