Cementation When minerals stick sediment together like glue.
Mineral A naturally-occurring inorganic solid that is the building blocks of all rocks
sedimentary rock a rock formed from sediment that has compacted and cemented together in layers
heat Energy in a substance due to its high temperature
pressure the addition of force through pressing
metamorphic rock a rock that forms when an existing rock is changed through heat and pressure
melting
recrystallization The process where crystals reform because of heat and pressure
Lithification The process that turns sediment into rock through compaction and cementation.
Chemical weathering The breaking down of rock by changing what the rock is made of.
Physical weathering The breaking of rock into smaller pieces without changing what the rock is made of.
