THE ROCK CYCLE

SEDIMENTARY ROCK

A SEDIMENTARY ROCK IS

• Formed by erosion
• Sediments are moved from 1 place to another
• They form at or nears earths surface
• There is no heat or pressure involved
• 3 different types is rocks
• Clastic:made of fragments of rock cemented together with calcite or Quartz
• Chemical sedimentary: minerals crystallize out of solution to become rock
• Organic sedimentary: remains of plants and animals
• Sediments-particles and other once living organisms
• Sedimentary-rock formed when particles of rock and other materials are pressed together
• Erosion-moves sediment from place to place flowing water,wind,and ice
• Deposition-sediments are laid down
• Cementation-sediments are glued together forming the rock

METAMORPHIC ROCK

WHAT IS METAMORPHIC ROCK

• Meaning to change shape
• Changes with temperature and pressure but will still remain solid
• Usually takes place deep in the earth
• 2 different types of rock
• Foliated:contain aligned grains of flat minerals
• Non-foliated:mineral grains are not arranged in plains or bands
• Metamorphic-rock formed from heat and pressure deep beneath the earths surface
• Examples of rocks are granite,gneiss,limestone,marble,sandstone,and quartzite

IGNEOUS ROCK

WHAT IS AN IGNEOUS ROCK

• A rock formed from magma or lava that cools and hardens
• Instrusive:formed from magma.formed below the earths surface.magma cools slowly forming larger crystals
• Extrusive:formed from lava.formed above earths surface.lava cools fast forming smaller crystals
• Example of some igneous rocks are granite and basalt

THE ROCK CYCLE

WHAT IA THE ROCK CYCLE

• It's a group of changes
• Igneous can change into sedimentary or metamorphic
• Metamorphic can change into igneous or sedimentary
• Sedimentary can change into metamorphic or igneous
• The rock cycle will never stop
