Is volcanic glass a mineral group?
No, volcanic glass is not a mineral group. It is a type of igneous rock formed from the rapid cooling of lava without the time for crystallization to occur, resulting in an amorphous (non-crystalline) structure.
What has to happen for metamorphism occur?
Metamorphism occurs when existing rocks are subjected to high temperatures, pressures, or chemically active fluids. This causes changes in the mineral composition, texture, or structure of the rocks, leading to the formation of new minerals or textures. Metamorphism can occur due to tectonic forces, burial in the Earth's crust, or interaction with hot fluids.
Why are diamonds made by people not considered minerals?
Diamonds made by people are not considered minerals because they are synthetic and do not occur naturally in the Earth's crust. To be classified as a mineral, a substance must be naturally occurring and have a specific chemical composition and crystalline structure. Since synthetic diamonds are man-made and not formed through natural geological processes, they do not meet the criteria to be classified as minerals.
Do metals in the earths atmosphere must be mined and separated from their ores?
Metals found in the Earth's crust must typically be mined and extracted from their ores in order to be utilized. Through mining processes, the ores are extracted and then undergo various separation techniques to isolate the desired metal for industrial and commercial applications.
What four things must a mineral have to be considered a mineral?
a mineral is defined as any inorganic substance that occurs in nature and has a definite chemical composition.
What must occur for a mineral to change into another mineral?
the mineral must melt ok honestly minerals must improve!
What type of condition must be for minerals fossilization to occur?
what type of conditionals must be present for mineral fossilization to occur
What must occur before precipitation can fall on earths surface.?
Evaporation and condensation
What mineral doesn't occur naturally but must be separated from its ore and its harder more rust-resistant form of this mineral is steel?
it is iron
Why do astronomers conclude that the crust on mars must be thicker than Earths crust?
Astronomers concluded that the crust on Mars must be thicker than Earth's crust because Mars lacks tectonic activity like Earth's plate tectonics, which recycles crustal material. This lack of recycling means that Mars's crust has likely accumulated over a longer period, resulting in a thicker crust compared to Earth's crust.
Which or the following must be true for a substances to be considered a mineral?
For a substance to be considered a mineral, it must be naturally occurring, inorganic, solid, have a specific chemical composition, and a crystalline structure. Minerals are typically formed through geological processes within the Earth's crust.
What type of conditions must be present for mineral fossilization to occur?
An important factor to make fossil formation more likely is rapid burial or coverage of the object so it isn't exposed to much air. There also needs to be an absence of decomposers.
Is oil is mineral?
No. By definition, a mineral must be a solid and have crystals
What mineral doesn't occur on earth naturally but must be separated from its ore?
Iron
Can minerals be liquid or solid or gas?
Rocks are made of minerals. When rocks melt, the minerals become fluid or in a liquid state. Also, when a mineral turns to a liquid it no longer meets the expectaions required for it to be called a mineral.
What substances must a mineral meet to be a mineral?
There must be oxegen, hydrogen, foam, water, and gases
Is volcanic glass a mineral group?
No, volcanic glass is not a mineral group. It is a type of igneous rock formed from the rapid cooling of lava without the time for crystallization to occur, resulting in an amorphous (non-crystalline) structure.
