Question

Why are active volcanoes used as evidence for the location of the boundaries of the floating rocks?​

Answer 1

Active volcanoes are used as evidence for the location of the boundaries of the floating rocks because they occur at the boundaries of tectonic plates where molten rock (magma) rises to the surface and forms volcanoes. The magma that forms these volcanoes is believed to come from the partially molten rock in the Earth's mantle, which is closer to the surface at the boundaries between tectonic plates. By studying the locations of active volcanoes, scientists can determine the approximate location of the boundaries between these plates and the areas where the plates are moving away from or towards each other. This information is important for understanding the geology of the Earth and for predicting and managing volcanic hazards.

Step-by-step explanation:

Answer 2

Active volcanoes are used as evidence for the location of the boundaries of tectonic plates because they often occur along the edges of these plates. When tectonic plates collide, move apart, or slide next to each other, it can cause magma to rise to the surface and create a series of active volcanoes. So, the presence of active volcanoes along the boundaries of tectonic plates provides evidence for the location of these boundaries.​
