The list of other possible causes for a drop in a personâs white blood cell count is long. Autoimmune disorders, congenital disorders that affect the way bone marrow works, disorders of the spleen, certain infectious diseases, cancer and parasitic diseases, among others, can all lead to low white blood cell counts.
Best Answer: Mountains can form at all three types of plate boundaries, convergent, divergent, and transform. At divergent boundaries new crust is being formed. The mid-Atlantic ridge is part of the longest mountain range on the planet, it just happens to be mostly covered by ocean.
Both fold mountains and ocean trenches result from plates moving together. If both landforms occur in the same area, they are found in association with subduction on a destru â¦ ctive plate boundary (e.g: The Andes Mountains, Western coast of South America). The Andes formed from the Nazca plate subducting under the South American plate. The continental plate crumples and folds. The result is a fold mountain range. The Andes is formed. If fold mountains occur by themselves, they are in areas where collision is taking place on a collisional plate boundary (e.g: The Himalayas). The Himalayas formed from two continental plates which collided into one another- The Indo-Australian plate collided into the Eurasian plate. They crumple and fold. The result is a fold mountain range. The Himalayas is formed.
