Hotspots are specific locations on the Earth's surface where volcanic activity is concentrated. They occur when molten rock, or magma, rises from deep within the Earth, often creating islands or volcanic chains. A well-known example of a hotspot is the Hawaiian Islands, which were formed as the Pacific tectonic plate moved over a stationary hotspot. In addition to volcanic activity, hotspots can also refer to areas with high biodiversity or significant ecological importance. These regions, such as the Amazon Rainforest, are crucial for conservation efforts due to their unique species and ecosystems. Protecting these hotspots is vital for maintaining global biodiversity.
