1.Rock cycle- rock cycle is the endless change of rocks and
magma. First the
magma get cool in the outside of volcanic, the
lava get cold down and become
igneous rock. Cool inside the volcanic is call
intrusive rock, the outside is call
extrusive rock. When the wind and waves keep and keep hit the igneous rock, this process is call
erosion and
weathering. This process keep and keep doing, igneous rock will broke into
sediment and sediments
cement together is call
sedimentary rock. When the sedimentary rock get heat and
pressure, it will become
metamorphic rock. When metamorphic get heat again, it will become magma again.
2.Rocks-vocabulary
Metamorphic rock-Rock change by pressure and heat.
Magma/lava- molten rock found inside the volcano.
Solidification- magma became solid by cooling.
Igneous rock- magma get cool down.
Weathiering-breaking rock into pieces.
Erosion-pieces rock get transported.
Sediment- sand.
Compaction-compress
Cementation-combine.
sedimentary rock- many sand combine together.
3.Rock types
igneous intrusive- cool inside the volcano with big crystals.
igneous extrusive- cool outside the volcano with small crystals.
sedimentary/clastic-dirty rock.
sedimentary/crystalline-formed under water.
sedimentary/bioclastic- form dead animal and plant.
metamorphic/foliated-with layer in the surface.
metamorphic/non-foliated -with no layer in the surface.
