Have you ever thought what is there inside the earth??
Well if you have or haven’t. This passage will explain to you what actually is there underneath the surface of the earth. There are four kinds of layers in the earth
- Inner core
- Outer core
Crust The crust is what you live on and you see all around you(if you are outdoors)the trees, the grass and all the tall buildings are located on top of the crust….There are two types of crusts – the oceanic crust and the continental crust… Temperatures of the crust can go up to 1000 degrees Celsius
Mantle THE MANTLE IS NOT A STATIONARY LAYER. IT MOVES AROUND THE EARTH THIS CAUSES EARTHQUAKES. TEMPERATURES CLIMB STEADILY UP TO 4500 DEGREES CELSIUS, THIS LAYER CONTAINS MOST OF THE MINERALS OF THE EARTH
Outer core The outer core is made of liquid iron and nickel temperatures rise up to 6000 degrees
Inner core The inner core is made of solid iron and nickel temperatures can go up to 7 to 9000 degrees Celsius
Amazing!!!!!! In 1983 scientists in Russia drove the deepest borehole into the earth crust.it was 12.261 m deep. The rocks at the bottom were 210 degrees C.
Earth’s weight!!!!! The inner core contains 1.7% of earth mass.The outer core 30.8%,the core-mantle boundary 3% the lower mantle 49 % the upper mantle 15%,the oceanic crust 0.099%and the continental crust 0.374%
