Study Notes
Sedimentary Rock Formation
- Sedimentary rocks are formed from sediment (small pieces of rock, mineral fragments, or organic matter)
- Sediment is transported and deposited in layers
- Stratification is the process of horizontal sediment layers forming
- Layers are deposited by water or wind
Foliation in Metamorphic Rocks
- Foliation is the parallel arrangement of minerals in metamorphic rocks.
- Schistose foliation is demonstrated by parallel layers of mica
- Slaty foliation occurs when a rock splits into parallel layers
Native Minerals
- Native minerals are composed of a single element
Conglomerate
- Conglomerate is a sedimentary rock formed from cemented pebbles and gravel
Shale Composition
- Shale is composed of clay and silt
Lithification
- Lithification is the process of cementing clastic rocks together
The Rock Cycle
- The rock cycle describes how rocks can transform into other types of rocks through various processes.
- Rocks can change by forces at Earth's surface and form other rocks.
Metamorphic Rock Foliation
- Slaty foliation is the characteristic of metamorphic rock splitting into layers parallel to each other
Fossils in Rocks
- Fossils are found in sedimentary rocks
Coquina
- Coquina is a sedimentary rock made of seashells
Weathering and Sedimentary Rocks
- Weathering breaks down rocks into sediment
Magma Types
- Basaltic magma forms in rifts or oceanic hotspots.
- Rhyolitic magma has the highest silica content.
Mineral Properties
- Luster refers to the way a mineral reflects light.
Crystal Formation
- Slow cooling magma results in large crystal formation
Mineral Identification Tests
- Hardness, color, and specific gravity are used to identify minerals but not weight.
Chemical Sedimentary Rocks
- Chemical sedimentary rocks are formed by dissolved minerals precipitating
