?@~ In science class we were asked to go to a special website called "The Dynamic Earth" and here is a link http://www.mnh.si.edu/earth/main_frames.html. We were also asked to make a blog poste after we were done visiting the website.And i learned that the earth is actually made of 4 layers. The crust were we live on, the mantel, the outer core and the inner core. The core is HOT, hotter than the surface of the sun! The mantle is actually rocky and the core is iron. If you look at earth as an apple the crust is as thin as the skin of the apple. The inner core is under such pressure that it is solid metal unlike the outer core is fluid liquid that is extremely hot.
Diamonds grow at the level of 150km underground.By comparing different types of carbon atoms in diamonds, scientist can track the carbon's source. Most of the diamonds originate in the mantel. Now, you may wonder " How do diamonds get to the surface of the earth well, they actually hitch a ride in rare magmas called kimberlite and lamproite, which from by partial melting of the upper mantel. They drive their diamond passengers up so fast that in 4-15 hours they are up on the crust. You can find diamonds beneath cartons the oldest parts of continents. Why there? Well, it is way too hot for them to form inmost of mother earths upper mantel, but the upper mantel below the cartons is quite cold that is why diamonds are stable there.
