1. Sedimentary Rocks:
* These are the most common type of rocks formed from fragments of other rocks, minerals, and organic matter.
* These fragments are called sediments, and they are transported and deposited by wind, water, or ice.
* Over time, these sediments are cemented together by pressure and chemical reactions, forming sedimentary rocks like sandstone, limestone, and shale.
2. Metamorphic Rocks:
* These rocks are formed when existing rocks (igneous, sedimentary, or other metamorphic rocks) are transformed by heat and pressure.
* The heat and pressure cause the minerals in the original rocks to recrystallize, forming new minerals and textures.
* Examples include marble (from limestone), slate (from shale), and gneiss (from granite).
3. Conglomerate:
* This is a type of sedimentary rock specifically formed from rounded fragments of other rocks cemented together.
* These fragments are often larger than the grains found in sandstone.
4. Breccia:
* This is another type of sedimentary rock similar to conglomerate but with angular fragments of other rocks.
So, depending on what you mean by "made of other rocks," the answer could be any of these rock types.
