Igneous Rocks – Helms PTA

Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth. Great globs of molten rock rise toward the surface. Some of the magma may feed volcanoes on the Earth''s surface, but most remains trapped below, where it cools very slowly over many thousands or millions of years until it …
