At the level of the iliac tubercle, a bony prominence on the lateral aspect of the crest 5 cm posterior to the anterior superior iliac spine, the FL is preferentially thickened and this represents the origin of the ITB.
The highest layer of earths atmosphere is the exosphere. The inner core has the most or highest amount of density (iron/nickel). I think its the core of the Earth with highest temperature with  6000 degree Celsius. The crust is the layer of the Earth that has the the lowest density. It depends a bit on what you consider being a part.
They divide the mass of the Earth by the volume, which gives the average density of the material in the earth as 3.2 ounces per cubic inch (5.5 g/cm3).. 5.5 g/cm3. The density of the Earth is higher than that of any other planet in our solar system. Sources vary when it comes to the density of the Earth. All the numbers that were provided are so close to each other, however, that they can each be considered valid.
