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'.
Volcanoes occur along both divergent sea-floor-spreading plate boundaries and convergent subduction boundaries, but the volcanoes are very different in character between them (the divergent plate boundaries having fissure flow eruptions and the convergent plate boundaries making strata volcanoes).olcanoes occur along both divergent sea-floor-spreading plate boundaries and convergent subduction boundaries, but the volcanoes are very different in character between them (the divergent plate boundaries having fissure flow eruptions and the convergent plate boundaries making strata volcanoes).
