How are friction ridges formed
WebThe skin is formed about 6 months before birth and remains persistent from infancy to death, with the exception of permanent damage or amputation. During fetal development … WebThese active volcanoes were formed by the subduction of oceanic plates under continental plates. In a subduction zone, an oceanic plate submerges into the mantle under a continental plate. The friction created by the plates' movement creates magma. When this magma reaches the earth's surface, a volcano is formed.
