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 inner core; outer core; mantle; and crust the core is the most dense because it has all the other layers pushing on it. A Different Answer: Scientifically, the Litho â¦ sphere is the least dense because it has no pressure from other layers against it. It is the crust and the upper mantle. The Asthenosphere is known as the weak sphere and it is under the Lithosphere which has more density from the pressure. The Mesosphere is the middle sphere.
