The Rock Cycle
Stuff elements minerals rocks
Exogenic Process
Endogenic
Base level= sea level (uniform position of all matter and material on Earth’s surface)
MAGMA- liquid deep- seduction zones
Weathering and decomposition
Building forces in interior of Earth
Balance, not equilibrium
Pg. 295
1. Igneous Rock Type- stemmed from magma
Enormous pressure/temperature
Radioactive/heat
Volcanoes/lava flows
Crest of Earth- exogenic processes, weathering, decompose smaller material
2. Sedimentary Rock Type
Cement
Sandstone
Decrease pressure
Transfer
Conglomerates
Mudstones
Limestones-chemical precipitant (calcium carbonate)
