Hot Spot
Usually because they are close to volcanic activity.
Mantle plumes
Areas of volcanic activity that develop above rising plumes of magma are called hot spots.
Andesite is abundant in Leyte due to the volcanic activity in the region. Leyte is part of the Pacific Ring of Fire, a region known for its high volcanic activity, which has resulted in the widespread presence of andesite. This volcanic rock is formed from the solidification of magma beneath the Earth's surface and is commonly found in areas with past or present volcanic activity.
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
Areas such as the mid-ocean ridges, volcanic arcs, and hotspots have extensive igneous rock records due to ongoing volcanic activity. Additionally, regions with ancient shield volcanoes, like the Canadian Shield and Fennoscandian Shield, also contain large amounts of igneous rocks from past volcanic activity.
People are typically attracted to volcanic areas due to the natural beauty and unique landscapes created by volcanic activity. Some people are also drawn to the sense of adventure and thrill that comes with visiting these dynamic and sometimes dangerous environments. Additionally, volcanic areas often offer opportunities for geothermal energy production, scientific research, and tourism.
Volcanoes in Canada are mostly located in these regions due to their proximity to tectonic plate boundaries where volcanic activity occurs. British Columbia is part of the Pacific Ring of Fire, a region known for its volcanic and seismic activity. Similarly, the Yukon Territory also lies along a tectonic boundary, resulting in volcanic activity in these areas.
