No -- it's a type of rock, often a composite. Primay types are igneous (made by fire -- vulcanism), sedimentary (sea beds) and composite (a mixture of other types). In almost every case, all of these types are defined as how the substance at hand was created and in most cases they are not pure minerals.

What would not be used to classify igneous rocks?

Color, as it is not a reliable indicator due to variations within the same type of rock. Texture, mineral composition, and formation conditions are typically used to classify igneous rocks.


Is the sodalite rock metamorphic igneous or sedimentary?

It's an igneous rock. There is a lot of fluorite in Illinois because this is an area of weakness in the bedrock where magma injections are present. Technically speaking, fluorite is a mineral, and not a rock. However, it is a mineral mostly formed in igneous area's


How can you tell igneous rocks apart?

Igneous rocks can be classified based on their texture and mineral composition. Texture is determined by the size of the mineral grains, with coarse-grained rocks forming from slow cooling and fine-grained rocks forming from rapid cooling. Mineral composition can also help differentiate igneous rocks, such as identifying the presence of minerals like quartz, feldspar, or olivine.


Would you expect a light gray igneous rock to be rich or poor in silica?

I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.


Which soil do you think would produce a more fertile soil those derived from the igneous rock or those that are derived from metamorpic rocks?

Soils derived from igneous rocks tend to be more fertile than those derived from metamorphic rocks. This is because igneous rocks have a higher mineral content that can break down into nutrients essential for plant growth. Metamorphic rocks may have fewer minerals available for plant uptake, resulting in less fertile soil.

What type of igneous rocks are easy to classify because the minerals that they contain can be seen and identified?

Rocks with large, easily identifiable minerals, such as granite and diorite, are easy to classify. These rocks belong to the intrusive igneous rock category and typically have distinct mineral compositions that allow for easy identification.


What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?

Extrusive igneous rocks have very small crystal grains.

How the mineral Quartz would be in an igneous rock and in a sedimentary rock?

Because the rock feels like it beotch.


The most common mineral earth's crust is the?

I would assume it would be igneous due to the massive amounts of magma in the earth's crust.

What observation about an igneous rock would support the inference that the rock cooled slowly underground?

The rock would have visible mineral crystals--a phaneritic texture.
