Types of Rocks
Grade 2 · Science · Earth and Its Resources · New Hampshire, USA
Lesson Summary
There are three main types of rocks: igneous, sedimentary, and metamorphic.
Explanation
Rocks are grouped into three types based on how they formed. Igneous rocks form when hot melted rock cools and hardens, like granite and obsidian. Sedimentary rocks form when layers of sand, mud, or tiny pieces build up over time, like sandstone and limestone. Metamorphic rocks form when other rocks are squeezed and heated deep underground, like marble. You can find all three types of rocks in nature!
