why does continental crust melt when impacted by a rising mantle plume underneath, even if the plume itself is bery hot but still solid

The crust can melt at the same temperature as the solid plume because the felsic continental material's liquid/solid line is located relative to the highly mafic mantle plume at a colder temperature. The decompression of rising clouds causes everything above them to melt. Lower lithosphere rocks are melted by the heat from the clouds. The heat of the clouds melts rocks in the lower lithosphere. The largest (and most persistent) mantle plumes are thought to form at the core-mantle interface about 1,800 miles below the Earth's surface where a large amount of mantle rock is heated, but other plumes in the mantle are thought to form. Small plumes can also form in places. Continental crust is thicker than oceanic crust, which ranges in thickness from 25 km to 70 km. Continental crust accounts for 70% of the Earth's volume and is usually above sea level. Most are submerged lies. Up to 40% of the Earth is made up of continental crust. Sedimentary, igneous, and metamorphic rocks make up the continental crust. It forms a flat submarine area near the continental upper layers and near the coast.Learn about continental crust:https://brainly.com/question/13630778#SPJ4
