Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of hotspot volcanism, where the magma is much hotter than the surrounding magma. These hotspots are stationary and do not move the tectonic plates. They are responsible for the creation of volcanic island chains.

Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of "hotspots" where the magma is much hotter than the surrounding magma. To understand this concept, one can refer to plate tectonics theory, which explains the movement of Earth's crustal plates. According to plate tectonics, there are three types of plate boundaries: divergent boundaries where plates move away from each other, convergent boundaries where plates collide, and transform boundaries where plates slide past each other.
However, there are volcanic activities that occur away from these plate boundaries, such as the creation of volcanic island chains. One explanation for this phenomenon is the concept of hotspots. A hotspot is an area in the mantle where there is an upwelling of abnormally hot magma. This hotspot remains stationary over time while the tectonic plates move above it. As the hot magma rises to the surface, it creates volcanoes, and as the plates move, a chain of volcanic islands is formed.
This volcanic activity associated with hotspots happens independently of plate movements. It is essential to note that hotspots do not move the tectonic plates themselves but instead produce volcanic activity in fixed locations. Examples of hotspot-related volcanic island chains include the Hawaiian Islands, the Galapagos Islands, and the Canary Islands.
In conclusion, the concept of hotspots explains how volcanoes can be located far from tectonic plate boundaries. The presence of abnormally hot magma rising from the mantle creates these hotspots, where volcanic activity occurs in fixed locations, resulting in the formation of volcanic island chains.
