Sedimentary
|
Rock formed as pieces of older rocks and other loose materials get pressed or cemented together or as dissolved minerals re-form and build up in layers.
|
|
Metamorphic
|
Rock formed as heat or pressure causes existing rock to change in structure, texture or mineral composition.
|
|
Igneous
|
Rock that forms as molten rock cools and becomes a solid.
|
|
Extrusive
|
Igneous rock that forms when Lava cools on Earth’s surface
|
|
Intrusive
|
Igneous rock that forms when magma cools below Earth’s surface
|
|
Compaction
|
When sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly.
|
|
Deposition
|
The process in which transported sediment is laid down.
|
|
Cementation
|
Where new materials stick the grains together
|
|
Erosion
|
The process in which sediment is picked up and moved from one place to another
|
|
Mechanical Weathering
|
The breakdown of rock into smaller pieces of the same material without any change in its composition.
|
|
Chemical Weathering
|
The breakdown or decomposition of rock that takes place when minerals change through chemical processes.
