Study Notes
Rock Groups
- Three main groups of rocks: Igneous, Sedimentary, Metamorphic.
Igneous Rocks
- Formed from cooling and crystallization of magma or lava.
Sedimentary Rocks
- Created by compacting and cementing weathered or eroded rock particles.
Metamorphic Rocks
- Result from existing rocks transformed by heat and pressure.
Geological Time Scale
- Rock changes occur over long time frames, spanning thousands of years.
Rock Cycle
- Illustrates how rocks are formed and recycled through geological processes.
Rock Transformation
- Any rock can change into any of the other rock types through various processes.
Conservation of Mass
- The mass of Earth's rocks remains constant; they only change forms.
Transformation Processes
- Sedimentary Rock becomes Metamorphic Rock through heat and pressure.
- Sedimentary Rock transforms into Sediment via weathering and erosion.
- Sedimentary Rock turns into Igneous Rock by first becoming Metamorphic Rock, then melting to form magma, which cools into Igneous Rock.
- Metamorphic Rock converts back to Sedimentary Rock through weathering and erosion.
- Igneous Rock also transforms to Sedimentary Rock via weathering, erosion into Sediment, followed by compaction and cementation.
- Igneous Rock can become Metamorphic Rock when subjected to heat and pressure.
Magma and Rock Types
- Magma turns into Igneous Rock through cooling.
- Magma can become Metamorphic Rock, first cooling into Igneous Rock and then undergoing heat and pressure.
- Magma transforms into Sedimentary Rock by cooling into Igneous Rock, which then erodes into Sediment and compacted.
Sediment Formation
- Sediment forms Sedimentary Rock through compaction and cementation.
Melting Process
- Igneous Rock transforms back into magma through melting.
Rock Cycle Definition
- The cyclical process of rocks changing from one type to another is known as the Rock Cycle.
