SUBDUCTION ZONES and ISLAND ARCS. Subduction Zones are where cool lithospheric plates sink back into the mantle. It takes about 50 my for the ocean lithosphere that formed in the hot (>1000C) environment at mid-ocean ridges to cool to an equilibrium state and sink to its maximum depth below sea-level.
Ebola hemorrhagic fever is a viral disease caused by Ebola virus that results in nonspecific symptoms (see symptom section of this article) early in the disease and often causes internal and external hemorrhage (bleeding) as the disease progresses.
Ebola strikes fear in people all around the world, and thereâs no reason it wouldnât. It first appears as many other infections â with headaches, sore throats, and fevers â and then quickly turns a personâs immune system against the bodyâs organs, causing blood vessels to explode, and internal and external bleeding.
