Certainly not: Igneous rocks vary in mineralogy from Felsic to Mafic, which encompassed all sorts of compositions. Does a Granite appear the same as a Basalt? No, because they have different mineralogies, and different minerals have different colours and textures. This is visible in every rock.
No, igneous rocks can have different mineral compositions depending on the cooling rate of the magma. Faster cooling can result in fine-grained rocks like basalt with minerals such as pyroxene and plagioclase, while slower cooling can lead to coarse-grained rocks like granite with minerals such as quartz, feldspar, and mica.
no, for example
Granite is made of potassium feldspar, quartz, playgirls feldspar, bootie's, and amphibian
Periodicity is composed of Pyroxene, Olivine, and Amphibian and maybe a very very very very small bit of Plexiglas feldspar
so no they are not made of all the same minerals
they are all different and they are not made of all the same minerals

What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
How do two igneous rocks have the same mineral composition but different textures?
Igneous rocks can have the same mineral composition but different textures due to variations in cooling rate and location of formation. For example, a rock that cools quickly on the Earth's surface will have a fine-grained texture, while a rock that cools slowly beneath the surface will have a coarse-grained texture. These different cooling rates can result in the same mineral composition but different textures in igneous rocks.
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.
What are two ways sedimentary and igneous rocks can be changed into metamorphic rocks?
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Two rocks that have the same general chemical and mineral composition?
Two rocks with the same general chemical and mineral composition could be both granite and diorite, which are both composed of feldspar and quartz. Another example could be basalt and gabbro, which both consist of minerals such as pyroxene and plagioclase. These rocks have similar compositions but different textures due to their formation processes.
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.

Why do the three rock groups contain the same basic composition?
The three main types of rocks (igneous, sedimentary, and metamorphic) have the same basic composition because they all originate from the same materials found in the Earth's crust. Igneous rocks form from cooling magma/lava, sedimentary rocks form from the accumulation of sediments, and metamorphic rocks form from the alteration of existing rocks under heat and pressure. This shared origin accounts for their similar basic composition.
Can two igneous rocks be made of the same minerals but have different names?
Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
How rocks are the same when they feel and look the same?
Rocks that feel and look the same likely share similar mineral composition and texture. Minerals present in the rock, as well as the way the rock formed (igneous, sedimentary, metamorphic), contribute to its appearance and feel. Thus, rocks that appear and feel the same are likely to be composed of similar minerals and have undergone similar geological processes.
How are the three types of rocks similar?
It all depends on the rock type in question. But basically, to an extent in terms of Igneous Composition, most Igneous rocks are composed of the Minerals; Quartz, Feldsper and Mica Mineral (either of/both the Muscovite and Biotite).
Is biotite a mineral or non-mineral?
Biotite is a mineral. It is a type of mica mineral that is commonly found in igneous and metamorphic rocks.
What are the limitations of using chocolate and butterscotch chips to represent igneous rock?
Using chocolate and butterscotch chips to represent igneous rock has limitations because these materials do not accurately mimic the physical and chemical properties of real igneous rocks. Chocolate and butterscotch chips do not have the same mineral composition, texture, or formation process as igneous rocks, so they may not provide a realistic representation for educational purposes.
