Rock Types

Rock Types

• Igneous Rock---Intrusive/Extrusive

Extrusive

Intrusive

Intrusive - The rock stay inside the volcano and change into rock slowly so the crystal comes out clearly.

Extrusive - The rock come out with magma and it cools down fast so the crystal will not show clearly.

• Sedimentary Rocks---Clastic/Crystalline/Bioclastic

Clastic

Crystalline

Bioclastic

Clastic - Clastic rocks are made up of particles
Crystalline -  Crystalline made up of clearly crystal 

Bioclastic -  Bioclastic is made up of arranged animals

• Metamorphic Rocks---Foliated/Non-Foliated

Foliated

Non-Foliated

Foliated -  The rocks have parallel bands.

Non-Foliated - The rocks that do not have parallel bands.

Vocabulary

Metamorphic rock -Metamorphic rocks are sedimentary or igneous rocks that changed by heat and pressure.

Magma/Lava - Melted rock inside the mountain. Lava is when the melted rock is indis/ Magma is when the rock come out.

Solidification - To make it solid

Igneous rock - Made up by cooling magma

Weathering - Weather(Rain/Sun/Wind)

Erosion - When water and wind take away things on the surface of the rock

Sediment - Sand and mud

Compaction - Push it together

Cementation - Grew together over time

Sedimentary rock - Rock that formed through the solidification

Summary

Sedimentary rock heat and pressure to metamorphic rock.

Metamorphic rock melting into magma.

Magma cooling down and turns into Igneous rock.

Igneous rock weathering and deposition into sediment.

Sediment change into sedimentary rock by compaction and cementation.

The sedimentary rock will heat and pressure into metamorphic rock.

Igneous rock and Sedimentary rock can both change into Metamorphic rock by heat and pressure

Crystals&Minerals

Crystals Growing Lab

In the Crystal growing lab, We melt up the sugar with hot water. Then we hung up a clip using cord and pencil to balance. We put the beaker close to the window. After few days the crystal will grew out!!!
