The earth
In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value. The earth is split into four major layers: the crust, the mantle, the outer core and the inner core. The crust is what humans live on, and it consists of only one percent of the Earth's mass. The centre of the Earth is a solid ball of nickel and iron roughly 70% the size of the moon. Geologists have come a long way in terms of the collective ...
