Final answer:
The subject of this question is Geography. It explores areas of earthquake and volcanic activity, such as mid-ocean ridges, rift valleys, and coral reefs. Tectonic plate movement and activity, including along rift zones and subduction zones, cause these phenomena.
Step-by-step explanation:
The subject of this question is Geography. It is concerned with the areas of great earthquake and volcanic activity, including mid-ocean ridges, trenchb rift valleysc, and coral reefs.
Earthquakes and volcanic activity are caused by tectonic plate movement, such as along rift zones like the Mid-Atlantic ridge and subduction zones. These activities result in the formation of volcanic islands, mountain building, and the creation of geological features like mid-ocean ridges and coral reefs.
Furthermore, tectonic plate activity in the region, particularly along the Ring of Fire, makes it vulnerable to earthquakes and volcanic eruptions, which have significant impacts on human life and the surrounding environment.
