Rocks make up mountains, hills, valleys, plains and they also form river and ocean beds. Rocks play an important role in our life as many minerals are derived from them. Rocks forming the ocean bed are rich source of crude oil and natural gas. Earth’s outermost solid layer known as lithosphere is made of all types of rocks.

All about Rocks

We all come across rocks in our day to day life, be it a stone, pebble, sand or just mud. Rocks are also classified on the basis of their hardness which ranges from 1 to 10 on Moh's Hardness Scale as types of hard rocks, types of soft rocks and rocks with medium hardness. At comparerocks.com, know all about rocks and get to know Rocks with Less Maintenance and Rocks with More Maintenance. All types of rocks undergo formation and transformation process. Formation of rocks depends on cooling of lava and then transformation process takes place. Every rock has an individual property due to which it has its own unique uses.

Rock Texture

Rock texture refers to shape, arrangement and distribution of grains within the rock. Some common rock textures are crystalline, fragmental aphanitic and glassy.

  • Crystalline texture- Texture in which crystals are interlocking and inter-grown.
  • Fragmental texture- Texture in which particles are broken or irregular.
  • Aphanitic texture- Texture in which crystals are not visible to naked eye.
