What are some non examples of texture in rocks?
Texture in rocks is not the same as color or shape. Texture refers to the size, shape, and arrangement of mineral grains or crystals within a rock, while color refers to the outward appearance of the rock. Similarly, shape in rocks refers to their physical form or structure, and not the internal arrangement of mineral grains which defines texture.
Why can two rocks look very different even though they have the same minerals?
The two rocks in question may have different percentages of the same minerals, or their method of formation could be different, which can affect the shape and size of the mineral grains. Trace minerals in the two rocks could also alter their appearance, as well as the amount of weathering the rocks have been exposed to.
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
Is it possible for two igneous rocks to have the same mineral constituents but different names?
Yes, it is possible for two igneous rocks to have the same mineral constituents but different names. This can occur if the rocks have formed under different conditions such as depth of burial, cooling rates, or chemical compositions, which can lead to different textures, structures, and overall classification.
Why are the minerals considered to be the building blocks of rocks?
By definition, rocks are composed of minerals. There is not a single rock that is not composed entirely of minerals. Rocks and minerals are essentially one in the same thing. However, not all rocks are made of just one mineral. The vast majority of rocks contain many different minerals. For example granite, a very common rock, consists of the minerals Quarts, Feldspar, Mica and Hornblende. Limestone, another common rock, consists of the minerals Calcite and Argonite. Marble, a derivative of Limestone, and a nonfoliated metamorphic rock, consists primarily of the minerals Calcite and Dolomite, and sometimes even a bit of Graphite, Iron Oxide, Garnet and Magnetite.
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.
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.
Why are rocks not the same?
Because different rocks are formed by different processes and made up of different mineral assemblages.

Is a rock and a mineral the same?
No. Rocks are combinations of minerals.
Metamorphic rocks with the same mineral assemblages belong to the same?
metamorphic facies. This indicates that these rocks formed under similar pressure and temperature conditions despite coming from different locations.
Is a rock and a mineral the same thing?
No. Rocks are combinations of minerals.
What is the least reliable way to classify a mineral?
color for instance real gold and fools gold is the same color but 2 different rocks
Is the cleavage for a mineral always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
