Question
Find the difference between
Igneous and sedimentary rocks
Solution
| Igneous Rocks | Sedimentary Rocks |
| These are formed due to the cooling and solidification of ‘magma’ and ‘lava’. | These rocks are formed due to continuous deposition and compaction of weathered pieces of rocks transported to various places by wind, glaciers, rivers, etc. |
| These are hard, homogeneous, and heavy rocks. | These are brittle, layered, and light in weight. |
| They lack fossils. | They show the presence of fossils. |
