Compaction of sediments into sedimentary rocks
Formation of igneous rocks
Metamorphism of sedimenatry into metamorphic rocks
Erosion of sedimentary rocks back to sediment
2
How are sedimentary rocks classified?
Lustre
How they were formed (clastic, chemical, and organic)
Colour
Particle size (breccia vs conglomerate)
3
Body of intrusive igneous rock crystallized from slow cooling magma below the Earth's surface:
Craton
Pluton

Creton
4
Why are mineraloids not classified as minerals?
Man made
Not valuable
Not in solid state
No definite crystalline structure
5
