Why western cordillera have hot springs and geyser?

The Western Cordillera, which includes mountain ranges like the Rockies and the Cascades, has hot springs and geysers primarily due to geothermal activity associated with tectonic processes. The movement of tectonic plates creates fractures and volcanic activity, allowing heat from the Earth's mantle to rise. This heat warms groundwater, leading to the formation of hot springs and, in some cases, geysers, which erupt when pressure builds up in underground reservoirs. The combination of volcanic activity and the presence of water creates these geothermal features commonly found in this region.
