Question

What are similarities and difference in the appearances of these types of rocks?

Answer 1

Like hunterswag11 said basically their formation is different. But another thing that is different is their chemical composition. So basically they are made up of different chemical materials but you can't see their composition from their outward appearance.

Answer 2

Differences and similarities between igneous , metamorphic , and sedimentary rocks . sedimentary rocks are formed by weathered sediment using cementation or precipitation on Earth's surface . Metamorphic rocks are formed by changes of pressure and temperature within Earth's surface .
