Fuse means, essential component is a metal wire or strip that melts when too much current flows, which breaks the circuit in which it is connected, thus protecting the circuit's other components from damage due to excessive current. I hope that helps.
Rift volcanoes occur where tectonic plates diverge, often on the ocean floor. These are generally less explosive. Hot spot volcanoes occur in the middle of plate boundaries where magma exits from weaknesses in the earth's surface. The Hawaiian Islands are an example of hot spot volcanoes. The most active area of volcanic activity occurs along the pacific plate boundary which is often referred to as the 'Pacific ring of fire'.
Most volcanoes occur around the edges of the tectonic plates. Hot spot volcanoes are different because they do not occur near the edges of a plate, but rather occur at quite a distance from the edges. The movement of these hot spots volcanoes can be tracked as well.ot spots often erupt continually and the lava creates basaltic rocks. There are cases in which the eruptions of hot spot volcanoes can be very explosive. This is due to the strength and weight of the rock and earth covering the volcano's mouth and the pressure accumulated by a lack of escape routes.
