This diagram illustrates how volcanoes can form in relation to tectonic plates. 1 / 2 Volcano Formation via Plate Tectonics The earth’s crust is composed of enormous sections of rock called tectonic plates. Tectonic plates resemble puzzle pieces and are constantly moving toward, against, and alongside one another. See more A volcano is a geological rupture in the earth's crust triggered by pressure, temperature, and other natural forces in the planet's interior. These forces drive gasses and hot liquid known as magma out through a … See more A volcano forms when pressure, temperature, and other natural forces push magma out of a magma chamber (a large, underground pool of liquid rock) until it erupts as lava on the … See more The earth’s crust is composed of enormous sections of rock called tectonic plates.
