B) The Pincer type. Cam Impingement. Cam literally means the projecting part of a cog-wheel. Cam deformity, also called the âpistol grip deformityâ or the âhead tilt deformityâ refers to an abnormal bony bump at the head neck junction of the femur.
Sedimentary rocks. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified â turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas.
Best Answer: Sedimentary rocks are formed because of the overburden pressure as particles of sediment are deposited out of air, ice, wind, or water flows carrying the particles in suspension. As sediment deposition builds up, the overburden (or 'lithostatic') pressure squeezes the sediment into layered solids in a process known as lithification ('rock formation') and the original connate fluids are expelled.
