those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks
yes,either felsic if light coloured or mafic if dark cloured.we classify rocks like that especially igneous rocks but COLOR IS NEVER USED TO IDENTIFY ANY ROCK.only classification.
They classify metamorphic rocks according to their parent rock or protolith.
cleavage, fracture, luster, streak and color
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.
Depends on how you categorize them. There are numerous types of rocks, and the number you come up with is just a representation of how specifically you classify them.
The three main categories into which geologists classify rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and lithification of sediments. Metamorphic rocks are created from the alteration of pre-existing rocks due to high temperature and pressure.
Geologists classify rocks into three groups. The first group are igneous rocks, the second are metamorphic rocks and the third are sedimentary rocks.
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
by carol and size
Igneous rocks form from the cooling and solidification of molten lava or magma. Sedimentary rocks are created from the accumulation and compaction of sediments like sand, mud, or organic material. Metamorphic rocks form when existing rocks are subjected to high temperatures and pressures, causing them to recrystallize without melting.
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
they look through a microscope
Color and texture is one way to classify igneous rocks. Another way to do this is modal classification and normative classification.

That was how racism was born.
