Sedimentary
What is a sedimentary rocks?
Pieces of solid materials that have been deposited on the Earth
The series of actions or steps taken in order to achieve a particular result.
What is a processes
name one out of the five ways you can identify a mineral?
color, luster, hardness, streak, and cleavage
What are the small ridges preserved in rocks formed by wind or waves
Ripple marks
The process of compaction and cementation that transforms layers of loose sediment into solid sedimentary rock
What is lithification
what is the difference between cleavage and fracture?
Cleavage is when a mineral breaks along smooth, flat planes of weakness, while fracture is an irregular break that does not form smooth planes
the removal and movement of material of materials from one location to another
erosion
The process by which high heat and uneven pressure, but not enough to melt the rock, cause minerals to realign into bands, creating a foliated texture
What is regional metamorphism
what is the first step to the forming of sedimentary rocks?
weathering and erosion
Sedimentary rocks are broken down into three categories. What are they
Inorganic
Chemical
Organic
The process by which rainwater, which is slightly acidic due to dissolved carbon dioxide, causes the slow dissolution of limestone to form features like caves
What is chemical weathering by carbonation
why isn’t color reliable when identifying minerals?
the same mineral can come in many colors, while different minerals can be the same color due to formation conditions
what are the formation of sedimentary rocks
Weathering
Erosion and transport
Deportion
Burial
Lithification
1.his term describes the process where high-grade metamorphic rocks melt slightly, creating a mixed igneous and metamorphic rock known as a migmatite(250 points)
2.the broad range of physical, chemical, and biological changes that alter sediments or sedimentary rocks after deposition, but before metamorphism, including the formation of chert nodules.

2.What is diagenesis
what is the chemical symbol for the element gold?
