A ... is a chimney-shaped intrusion and magma move upwards through this to the surface A) lopolith B) dyke C) pipe D) sill

A pipe is like a geological elevator for magma, allowing it to rise from deep within the Earth and eventually erupt at the surface. These structures can lead to the formation of volcanoes and are often the sites of explosive volcanic activity. Think of them as nature's way of plumbing! Dykes and sills are also important, but they run horizontally or are intrusions that lie flat. Dykes cut through layered rock formations, while sills are parallel to those layers. Understanding these differences is vital for deciphering Earth's chaotic geological history!
