Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
Is dacite intrusive or extrusive?
Dacite can be both intrusive and extrusive. Intrusive dacite forms when magma solidifies beneath the Earth's surface, while extrusive dacite forms when lava erupts on the Earth's surface and cools quickly.
What is the grain size of fine sand?
The grain size of fine sand typically ranges from 0.075 to 0.425 millimeters in diameter.
The factor by which grain size increases with each texture category?
Grain size typically increases by a factor of 2-4 for each texture category. For example, from fine to medium grain size, there is a doubling or quadrupling of grain size. This progression helps geologists classify rocks based on their crystal sizes.
What is relative grain size?
Relative grain size refers to the comparison of the size of grains in a material, typically in the context of metallurgy or geology. It is often expressed in relation to a standard or reference grain size, allowing for the evaluation of grain growth or refinement during processes like annealing or solidification. This concept is crucial for understanding the mechanical properties of materials, as grain size can significantly influence strength, ductility, and overall performance.
What is obsidian's grain size?
there is no visible grain size

What term has the definition of grain size?
Particle size is another name for the term grain size.
What is slate's grain size?
Slaet in grain size is the size of sand crystals.
What is the dacite's habitat?
Dacite does not have habitat because it is not a living thing; it is a kind of rock. Specifically, dacite is a volcanic rock, so it will be found on and near volcanoes, typically stratovolcanoes.
How big is one grain?
The size of a grain can vary depending on the type, but generally, a grain is around 1-3 millimeters in size. Grain size can also be influenced by factors such as processing and variety.
What is the grain size of fine sand?
The grain size of fine sand typically ranges from 0.075 to 0.425 millimeters in diameter.
What is the difference in composition between a dacite and an andesite?
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.
Grain size for bituminous coal?
The grain size of bituminous coal typically ranges from 0.5 to 2 inches. It is considered a medium-grain size coal, with a balance of fine and coarse particles. The grain size can vary depending on the specific source and processing of the coal.
What is the grain size of coal?
The grain size of coal can vary, but it typically ranges from fine particles to larger chunks. Coal can be classified based on its grain size as fine, medium, or coarse coal. The grain size of coal can impact its combustion efficiency and handling characteristics.
What is the dacite rock used for?
Dacite rock can be used for filler in aggregate. It is used to build roads but not on concrete areas because it has a high silica content. Ancient civilization used the dacite rock to make tools.
