Minerals 1
This is a naturally occurring, inorganic, crystalline solid that has a definite chemical composition.
What is a mineral?
This is a mineral made of atoms of just one element.
What is a native mineral?
This is the solid material in the earth's crust that is a natural combination of two or more minerals or other materials.
What is a rock?
This is the size, shape, and appearance of individual rock particles, mineral crystals, and even fossils.
What is rock texture?
This is any remains or trace of a formerly living thing preserved by natural processes.
What is a fossil?
This is the powdered version of a mineral that is the most reliable way to identify the mineral.
What is streak?
This is crystal growth by atoms or ions adding one by one to the existing crystal structure.
What is accretion?
All intrusive and extrusive igneous rocks contain these types of minerals.
What are silicate minerals?
These are pegmatite, porphyry, and phanerite.
What are the three kinds of coarse-grained igneous rock?
This is required for fossils to form in the first place.
What is rapid burial?
These are mineral sediments that wash into streams and beaches which contain precious metals.
What are placer deposits?
These are cracks in rocks filled with native metals.
What are veins?
These are rocks made of sediments that are weathered, eroded, deposited, and compacted.
What are sedimentary rocks made of?
Erosion, solution, transportation, deposition, compaction, and cementation are these.
What are the steps of the sedimentary rock formation process?
This is where the best-preserved fossils can be found.
What are sedimentary rocks?
These three mineral groups contain metals useful to industry.
What are oxides, sulfides, and carbonates?
These are Silicon, Oxygen, and sometimes one or more metals.
What are silicates made of?
These types of igneous rocks form at low pressure within turbulent lava flows or as ejected materials, which does not allow crystals to grow very large.
How do fine-grained igneous rocks form?
These are the three agents of metamorphism in rock.
What are high temperature, pressure, and hydrothermal fluids?
These are amber, ice, and asphalt.
What are the three fossil traps?
These are nail files, knife blades, glass, coins, and fingernails.
What are common objects used to estimate relative hardness of a mineral?
These are conglomerates, sandstones, siltstones, and shales.
What are the four types of clastic sedimentary rocks?
These factors affect grain size in a rock.
What are magma composition and temperature, high pressure, seed crystals, and the rate of crystal formation?
These are casts and molds, trace fossils, original materials, petrified fossils, microfossils, and carbon prints.
What are the six kinds of fossils?
