1 Characteristics and Examples of the Three Different Rock Types

2 Metamorphic CharacteristicsFormed under the surface They have ribbon like layers May have shiny crystals showing, which is crystals that were formed SLOWLY overtime

3 Igneous CharacteristicsWhen lava cools QUICKLY, there are no crystals showing. The rock appears to look shiny and glasslike(OBSIDIAN) Tiny gas bubbles can sometimes get trapped in the rock (during the cooling process) This will leave small holes and spaces in the rock.

4 Sedimentary CharacteristicsFormed from particles of sand, pebbles, rock, shells and other material. Together, all of these particles are called SEDIMENT This type of rock is generally soft and can easily break apart or crumble easily Sediment accumulates in LAYERS
