Studying the effect of Rheumatoid Arthritis (RA) on tendons. Tenosynovitis is one of the common features of rheumatoid arthritis in the hand. It affects both the extensor and flexor tendons, sometimes leading to granulomatous involvement and tendon rupture. The commonest sites of rupture are well known but the areas of more general tendon involvement are less understood.
exists and is an alternate of . The main process by which mountains form is through tectonic activity. When two tectonic plates collide, the crust is crumpled and pushed upwards to form mountains (as an analogy, imagine the effect of pushing a rug up against the wall).
Explain how studying mountain ranges can help scientists learn more about plate tectonics and continental drift. Because plate tectonics are what a mountain is caused by. Continental drift would tell you how it moved. Continents also cause mountain ranges to form. Describe how volcanoes form at subduction zones. Because two plates collide and one goes under and then they push upwared to make a volcano.
