Web11 jan. 2024 · Magma chambers are located where the heat and pressure are great enough to melt rock. These locations are at divergent or convergent plate boundaries or at hotpots. The chemistry of a magma determines the type of igneous rock it forms. The chemistry also determines how the magma moves. WebThey are the world's most common volcanic landform. As the name "cinder cone" suggests, they are cone-shaped hills made up of ejected igneous rocks known as "cinders". These small volcanoes usually have a circular footprint, and their flanks usually slope at an angle of about 30 to 40 degrees. Most cinder cones have a bowl-shaped crater at the top.
