A liver transplant is surgery to replace a diseased liver with a healthy liver from another person. A whole liver may be transplanted, or just part of one. In most cases the healthy liver will come from an organ donor who has just died. Sometimes a healthy living person will donate part of their liver. A living donor may be a family member. Or it may be someone who is not related to you but whose blood type is a good match. People who donate part of their liver can have healthy lives with the liver that is left.
Stratovolcanoes are typically located on continental crust above subducting plates and are easily recognized by their often beautiful symmetrically-shaped cones (Mt. Fuji in Japan is probably one of the better known examples). Photo of Mt. Hood in Oregon, a stratovolcano that has been somewhat eroded by glacial activity.
Stratovolcanoes are steep-sloped volcanoes composed of layers of ash, tuff, and lava flows. They can erupt a wide virtually any type of volcanic material, ranging from basalt, to rhyolite, and even carbonatite.
