INSIDE EARTH

  CAN NOT EXPLORE MUCH OF EARTH -OUR DEEPEST MINES ONLY 

TRAVE ABOUT 1.6 KM (1MILE) INTO THE CRUST .HOWEVER

THERE ARE SCIENTIFIC WAYS TO FIND OUT WHAT IT IS LIKE INSIDE.

geologists able to study rocks from all depths within 

earth crust , because  collision between continents push up

rock that used to be below the surface forming  mountains.

in some areas ,collisions have even unearth vast swathes 

of the mantle. under the mantle is the core , which has never been 

seen at at the surface . however , scientists have used the waves from earthquakes to work

out that the core is split into two layers -a liquid outer core and a solid inner core.

 VOLCANOES IN HAWAII

the Hawaiian island in the mid -pacific have been  built by volcanic eruptions. the rock that

formed them was pushed to earth surface by hot rock moving upward in the mantle.

LAYERED EARTH

EARTH IS MADE UP UP OF MANY ROCKY LAYERS .THE TOP LAYER

IS THE CRUST .BEOW THAT ,UNIFORM AND SLIGHT DENSER ROCK FORMS THE MANTLE

FORM A SINGLE RIGID LAYER TOGETHER , WHICH IS CALLED THE LITHOSPHERE

THIS IS BROCKEN INTO SECTIONS CALLED TECTONIC PATES .

BELOW THE LITHOSPHERE IS THE ASTHENOPHERE .

ONLY TINY PARTS OF THE ASTHENOPHERE ARE LIQUID , BUT IT IS SOFT ENOUGH

TO MOVE,PUSHING AROUND THE PLATES ABOVE. UNDER THE MANTLE LIES THE CORE .

THE OUTER CORE IS A LIQUID MIX OF IRON AND SULPHUR , WHIL THE  INNER CORE IS 

SOLID IRON AND NICKEL.

THE ATMOSPHERE

EARTH ATMOSPHERE IS MADE UP OF GASES, WHICH ARE HELD IN PLACE BY GRAVITY .

THERE IS NO CLEAR BOUNDARY TO THE OUTR EDGE OF THE ATMOSPHERE- IT JUST 

FADES INTO SPACE. "OUTER SPACE " IS GENERALLY THOUGHT TO BEGIN ABOUT

100KM (62MILES) ABOVE THE SURFACE.

WHAT MAKES A CLIMATE

A CLIMATE IS AN AVERAGE WEATHER PATTERN THAT OCCURS IN

A SET AREA OVER MANY YEARS . THE CLIMATE EXPERIENCED AT A

CERTAIN LOCATION IS INFLUENCED BY ITS DISTANCE FROM THE EQUATOR, 

ELEVATION ABOVE SEAA LEVEL, THE AMOUNT OF SUNLIGHT IT GETS, AND HOW 

NEARBY  CIRCULATION PATTERNS IN THE OCEAN AND ATMOSPHERE AFFECT IT.
