Definition: A pluton is a deep-seated intrusion of igneous rock, a body that made its way into pre-existing rocks in a melted form (magma) several kilometers underground, in the Earth's crust.
Scoria is a kind of rock produced by volcanic activity. Like pumice, it forms when lava which is rich in gas cools quickly. It forms when molten rock is rising in a volcanic pipe, the decreasing pressure allows the gas to expand out (like opening a can of soda releases carbon dioxide). Scoria. Scoria rocks can either form inside the volcano, and be ejected out in eruptions. Or it can erupt as lava that cools quickly before the gas bubbles can escape the rapidly cooling rock. Scoria is similar to pumice, in that it has bubbles of gas trapped within it, but the bubbles are much smaller.
