... The outer 75 km (with big variations between 10 and 300km) of the earth is a region which does not get heated up to near-melting because it is losing heat rapidly to the surface - it is stuck at a temperature close to 0°C. This relatively cool shell is called the lithosphere. The lithosphere is frac ...

Layers Of the earth
... The crust is the outermost layer of the Earth. It is the familiar landscape on which we live: rocks, soil, and seabed. It ranges from about five miles thick beneath the oceans to an average of about 25 miles thick way beneath the continents. The interior of the Earth cannot be studied by drilling ho ...

History of geodesy
Geodesy (/dʒiːˈɒdɨsi/), also named geodetics, is the scientific discipline that deals with the measurement and representation of the Earth. The history of geodesy began in antiquity and blossomed during the Age of Enlightenment.Early ideas about the figure of the Earth held the Earth to be flat (see flat earth), and the heavens a physical dome spanning over it. Two early arguments for a spherical Earth were that lunar eclipses were seen as circular shadows which could only be caused by a spherical Earth, and that Polaris is seen lower in the sky as one travels South.
