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.
Okay in my homework it ask me what part of the Earth is the coldest so i know that the that the inner core is the hottest layer of the the Earth but I'm not quit sure what the coldest layer is so peoples please help me out! thank you and i really appreciate it! have a blessed week.
