QUESTIONS
1.
a) The earth's inner core is just a few hundreds of degrees less than the temperature of the
Sun: about 5200 degrees Celsius versus about 6000 Degrees Celsius. With that much heat
in the centre of the earth, why is it still possible for life to exist on the surface of the
earth?
b) How is the heat in the earth's centre able to melt the outer core but not the inner core?
2). a). Describe the Goldsmith Classification of element.
b). Describe how Goldsmith rules are used to classify Elements.
c). Describe how the bonding types and magma differentiation aids in the distribution of
trace elements in the Earth
