The main difference between Igneous Rocks and Sedimentary Rocks: Igneous rocks form from cooling magma, while sedimentary rocks form from consolidated sediments. Understanding rock types is fundamental to geology in CBSE
Igneous Rocks vs Sedimentary Rocks — Comparison Table
| Basis | Igneous Rocks | Sedimentary Rocks |
|---|---|---|
| Formation | From cooling and solidification of magma | From compaction of sediments over time |
| Origin material | Molten rock from within Earth | Fragments of existing rocks and minerals |
| Crystal size | Large crystals if cooled slowly underground | No visible crystals usually |
| Examples | Granite, basalt, pumice | Sandstone, limestone, shale |
| Density | Denser rocks | Less dense rocks |
| Fossils | Rarely contains fossils | Often contains fossils |
| Cooling rate | Depends on cooling speed | Formed slowly through cementation |
Key Points
- Igneous rocks form from magma; sedimentary rocks form from erosion products
- Granite (igneous) has large crystals; basalt (igneous) has small crystals
- Sedimentary rocks are more likely to contain fossils and are softer
- Both rock types are part of the rock cycle and can transform into each other
