Rock Cycle

There are three types of rocks: igneous, sedimentary, and metamorphic.

These are formed differently than one another and have identifiable characteristics.

• These rocks are formed from cooling lava and magma.

• The lava and magma cool forming solid and crystallizing.

• If it cools underground, it is called intrusive.

• If it cools above ground, it is called extrusive.

• ​Include more than 1 mineral

• Can be glassy or coarse

• Large crystals if cooled slowly​

• These rocks are formed by the build up of sediments (weathered rocks) or fossils.

• The sediments and fossils are pushed together or become cemented in water.

• They can display many layers or the individual parts that make the rock.

• ​Includes pieces of other rocks or living things.

• Layers are possible due to deposition​

• Fossils are most commonly found in these types of rocks.

• These rocks are formed in areas of high temperature and pressure changes.

• The crystals are in the rock are changed and form a new rock.

• Located deep in the Earth's crust

• Commonly seen with zigzags or stripes due to squishing and squeezing

• ​Wide range of luster, color, density, and minerals

• Uniq​ue minerals located in these type of rock

• This is the process on Earth that recycles matter into new matter.

• Rocks are always moving in this cycle.

• The path may change depending on the conditions.
