the thickness of the mantle: Earth's mantle is ~2,890 km thick (1,800 miles)[1] rocky shell comprising approximately 70% of Earth's volume. (http://zh.wikipedia.org/w/index.php?title=%E5%9C%B...

depth of boundary of the mantle :about 35km (puiching.edu.hk/~pc-wcwm/ F4_Mountain/ Plate_Tectonics_Final_00-01.doc)

the density of the mantle:3.3-5.5g/cm3 (http://zh.wikipedia.org/w/index.php?title=%E5%9C%B...

the density of the outer core: 9.9~11.1 inner core :12.8~13.1 (www.hko.gov.hk/education/ edu03course/ coursenotes/earthquake_notes.pdf )
