Which an igneous rock to be classified as rhyoriteit must be light colored be fine grained and contain?
To be classified as rhyolite, an igneous rock must be light-colored, fine-grained, and primarily composed of quartz and feldspar. It typically has a high silica content, which contributes to its lighter coloration. Rhyolite often forms from the rapid cooling of lava during volcanic eruptions, resulting in its fine-grained texture. Additionally, it may contain small amounts of other minerals like biotite or hornblende.

Which the following is a fine grained light colored extrusive igneous rock?
fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
Basalt is an example of a n?
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
Was igneous rocks were classified by their their origin texture and shape?
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
What are three types of igneous rock?
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.
What is the name used to refer to all fine-grained sedimentary rocks?
Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).

This igneous rock is coarse-grained. The dark-colored mineral composing this rock is probably?
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Basalt is an example of a n?
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
Was igneous rocks were classified by their their origin texture and shape?

What are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.
What are large-grained light-colored rocks that form deep inside earth composed of what type of magma?
Igneous
What large-grained light-colored rock forms deep inside Earth and is composed of magma?
granite or granitic
What factors affect the texture of igneous rock?
The cooling rate of magma is the primary factor that affects the texture of igneous rocks. Rapid cooling results in fine-grained texture, while slow cooling leads to coarse-grained texture. The mineral composition of the magma also influences the texture, with high silica content producing light-colored and fine-grained rocks, and low silica content resulting in dark-colored and coarse-grained rocks.
Which object will MOST likely contain a fossil?
rock.A2. A fine-grained sedimentary rock.
Name 5 igneous rocks and how to recognize them?
Basalt: Dark-colored rock with fine-grained texture, typically found in oceanic crust and volcanic areas. Granite: Light-colored rock with coarse-grained texture, often containing visible minerals like quartz, feldspar, and mica. Obsidian: Dark, glassy rock formed from rapidly cooled lava, lacking visible crystal structures. Pumice: Light-colored, porous rock that floats on water due to trapped gas bubbles. Andesite: Intermediate-colored rock with medium-grained texture, commonly found in volcanic arcs.
An example of light-colored coarse-grained intrusive igneous rock is?
Granite is a light-colored, coarse-grained intrusive igneous rock. It is primarily composed of minerals like feldspar, quartz, and mica, and its large crystals are visible to the naked eye. Granite is widely used in construction and sculpting due to its durability and aesthetic appeal.
