Study Notes
Igneous Rock and Volcanic Eruptions
- Igneous rock is often associated with volcanic eruptions due to its formation from the cooling and solidification of molten magma or lava.
Characteristics of Igneous Rock
- The main characteristic of igneous rock is its crystalline texture, which results from the arrangement of mineral crystals formed during cooling.
Sedimentary Rock Formation
- Sedimentary rock is formed through active sedimentation, typically occurring in ocean environments where sediments accumulate over time.
Non-Igneous Rock Characteristics
- Characteristics such as layered structure are NOT associated with igneous rock, as these features are more common in sedimentary rocks.
Process of Sedimentary Rock Formation
- The main process involved in the formation of sedimentary rock includes the compaction and cementation of sediments over geological time.
Non-Characteristics of Sedimentary Rock
- Features like crystalline texture are NOT characteristic of sedimentary rock, which usually has a more granular or layered appearance.
