How hotspot volcanoes form
Web23 jul. 2024 · 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. WebVolcanic hot spots are plumes of molten rock which rise from the mantle and cause the crust to melt, creating magma resulting in volcanic activity. The map below shows the …

The latter form over subduction zones, at converging plate boundaries. When one oceanic plate meets another, the denser plate is forced downward into a deep ocean trench. This plate, as it is subducted, releases water into the base of the over-riding plate, and this water mixes with the rock, thus changing its composition causing some rock to melt and rise.
