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.
How do geologists classify igneous rock?
Geologists classify igneous rocks based on their mineral composition, texture (grain size and arrangement of crystals), and overall chemical composition. Igneous rocks are further categorized as intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface) based on where they solidified.
Rocks are to geologists as stars are to?
Rocks are to geologists as stars are to astronomers.
Geologists can use sedimentary rock to lean about climate in the past?
Geologists can analyze sedimentary rocks to infer past climate conditions by examining features such as grain size, composition, and layering. These rocks often contain fossils and sedimentary structures that indicate environmental conditions at the time of deposition, such as the presence of water or vegetation. For example, coal deposits suggest lush, swampy environments, while desert sandstones indicate arid conditions. By studying these characteristics, geologists can reconstruct historical climate patterns and changes over geological time scales.
Which industries often employ geologists?
Some geologists work for quarries, mines, or oil and gas companies (many jobs in Calgary, Alberta, Canada).

Is a donut a a grain?
Eggs are not a grain. According to the revised USDA food pyramid, they are a protein.

Igneous rocks are further categorized as intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface) based on where they solidified.
What are the 4 ways that geologists classify rocks?
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), grain size (fine-grained, coarse-grained), mineral composition (feldspar-rich, quartz-rich), and texture (foliated, non-foliated).
What is the plural of geologist?
The plural of geologist is geologists. As in "the geologists are studying the meteor sample".
Who are the scientist study biology?
geologists!!! ... "biologists" not "geologists"...
What are people called that study the earth and rocks?
That would be a geologist? Or if you wanted a name: http://en.wikipedia.org/wiki/List_of_geologists
Does obsidian a glassy rock have a large grain size or a small grain size?
Actually, obsidian doesn't have grains at all. Technically obsidian is a glass, which means it has no internal structure. When geologists refer the the grain size of a rock, they mean how big the crystals that make it up are. Since obsidian has no crystals, it therefore has no grain size.
What types of geologists are there?
There are different types of geologists that study oil exploration, mineral exploration and mineral mining. There are also engineering geologists.
How composition and texture are used to classify rock?
mineral composition is the minerals that the rocks are made of texture refers to the grain size (sediments or interlocking crystals) of the different components of that rock
Why do geologists use rocks?
Geologists don't use rocks, they study them.
Rocks are to geologists as stars are to?
Rocks are to geologists as stars are to astronomers.
