WebAreas where volcanoes that form on land away from tectonic plate boundaries are known as hotspots. These volcanoes are formed when hot magma rises through intrusions in the crust known as mantle plumes. Hotspots form above stationary regions of extremely hot magma under the earth’s crust. WebPart 3: Comparing Individual Volcanoes Another way to determine the cause of volcanoes on other planets is to compare the two types of volcanoes on Earth with volcanoes on other planets. Composite volcanoes (e.g., Mount St. Helens) usually form at plate tectonic boundaries and have steep slopes; shield volcanoes (e.g., Hawaii) usually form at hot …
