Two Distinct Origins
Two Distinct Origins is a skill on Pengi from Lesson 1: Rock Identification in Amplify Science (California) Grade 7.
Key Concepts
Rocks originate from two very different natural processes. Igneous rock is born from extreme heat; it forms when magma (molten rock) cools down and hardens into a solid.
Sedimentary rock , however, is born from accumulated debris. Over time, layers of loose sediment (sand, mud, and pebbles) build up and harden into stone. Recognizing these two formation paths explains why the Earth’s crust is made of different types of materials.
