Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.

What Are Biodiversity Hotspots?
Biodiversity Hotspots are biogeographic regions that have the richest and the most threatened reservoirs of plant and animal life on earth. These regions have been identified as some of the world’s most important ecosystems that are home to a high number of endemic species that also provide crucial ecosystem services for the benefit of humans.
What are the threats to biodiversity?
The biodiversity hotspots around the world are facing severe threats from several anthropogenic activities like deforestation, forest fires, climate change, and poaching. Large swathes of forests have also been cleared for the expansion of agriculture, exploitation of natural resources, construction of roads, railways, dams, and housing for the burgeoning human population. This loss of large forest areas results in the alteration of the natural landscape, habitat loss, and extreme fragmentation of wildlife habitats, eventually leading to the rapid decline in the number of endemic species harbored in the hotspot region. Some of the invasive floral and faunal species that have been introduced due to human activities in different habitats subsequently eliminate the native species, thereby harming the ecosystem. The effects of anthropogenic climate change, urban tourism, and other recreational activities also put tremendous pressure on these fragile ecosystems.
