Question
Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of Response area, where the magma s much hotter than the surrounding magma. These are Response areaand do not move with tectonic plates. They are responsible for the creation of Response areaisland chains.

It sounds like you're describing the concept of "mantle plumes" and "hotspots." Hotspots are volcanic regions that are often located far from tectonic plate boundaries. They are associated with columns of hot mantle material that rise from deep within the Earth, creating areas of volcanic activity.
Here's a more detailed explanation:
1. **Hotspots**: These are areas in the mantle that are significantly hotter than their surroundings. When a hotspot melts the rock above it, it can produce magma that leads to volcanic activity.
2. **Response Areas**: While "response areas" isn't a standard term in geology, it seems you're referring to these hotspots where the increased temperature generates magma that can lead to volcanism.
3. **Island Chains**: As tectonic plates move over a stationary hotspot, the volcanic activity can create chains of islands. An example of this is the Hawaiian Islands, which were formed by the movement of the Pacific Plate over the Hawaiian hotspot.
Overall, hotspots provide a mechanism for volcanic activity in regions that are not located at the edges of tectonic plates, and they can result in the formation of significant geological features like island chains.
