Describe the nature and mode of origin of the major types of rock at the earth's crust.

Type of Rock | Nature | Mode of origin

Igneous Rocks | Primary form; no fossils; high mineral composition | 1) Volcanic lava comes out due to high pressure and temperature - atrue release. 2) Freezing of lava to form igneous rock.

Sedimentary Rocks | Distinguished seistion & transport pattern | 1) Disintegration of weathered rock. 2) high fossils. 3) Easily breakable. 4) NO stratified layers. 5) mixture 2 outside both. 6) E.g Basalt, Granite

Metamorphic Rocks | Very high strength; thermal metamorphic contact sedimentary metamorph | 1) Strength of minerals. 2) Usually-shiny 2 polished. 3) E.g Diamond, Amethyst (Gem stone)

Thus, the rock cycle is sustained by three endo and exogenetic change leading to varied rock type.

Metamorphic Rock showing: Thermal metamorphic contact; Cataclasis metamorphism. Regional metamorphic - eon showing form laying by cementation-dewy seismic.

Detailed analysis of rock types showing distinguishing seistion & transport patterns; band patterns; oil & natural gas potential; easily breakable; stratified; E.g. Slate, Limestone showing specific pressure temperature conditions creating particular minerals.

Thus, the rock cycle is sustained by three endo and exogenetic change leading to varied rock type.
