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.
The density of Mercury is the second highest in the Solar System. Earth is the only planet that is more dense. It is 5.427 g/cm 3 compared to Earthâs 5.515 g/cm 3. If gravitational compression were to be removed from the equation, Mercury would be more dense. The high density of the planet is attributed to its large percentage of core.
