Time to Rock Your World !

Rock or Mineral: What’s the Difference ? There Is a big difference ! Minerals are made of a combination of elements and rocks are made of minerals. Which is a ROCK and which is a MINERAL ?

So How are Rocks Made ? Many processes go into making a rock. Probably the most important item needed to make a rock is TIME ! ! ! Some of the processes that make a rock are: Compaction and Cementation Weathering and erosion Heat and Pressure Melting Cooling and crystallizing

This is a Rock’s Life All rocks begin as magma. When the magma cools and crystallizes, it becomes an IGNEOUS rock.

Weathering and erosion break down the igneous rock into SEDIMENTS that get compacted and cemented together to form a SEDIMENTARY rock.

As the sedimentary rock has heat and pressure applied to it, it becomes a METAMORPHIC rock.

Over time, the metamorphic rock melts and cools then the whole cycle starts again !
