Rocks are composed of minerals, which are natural, inorganic substances with a specific chemical composition and crystal structure. Different types of rocks have varying mineral compositions and can include minerals such as quartz, feldspar, mica, and calcite. Rocks form through geological processes like cooling and solidification of molten materials, compression of sediment, or alteration of existing rocks.
The minerals within a rock that contain iron, such as iron oxides or sulfides, are the parts that can undergo rusting when exposed to oxygen and water. This process results in the formation of rust or iron oxide on the surface of the rock.
Minerals that contain silicon and oxygen are called silicates. Silicates make up the majority of the Earth's crust and are found in a wide variety of rock types, including quartz, feldspar, and mica.
Bauxite is not ferrous because it does not contain iron. Bauxite is a sedimentary rock primarily composed of aluminum minerals, such as gibbsite, boehmite, and diaspore.
No, gneiss does not fizz when hydrochloric acid touches it. Gneiss is a non-reactive metamorphic rock that does not contain calcite, which is needed for fizzing to occur.
If the limestone rock fizzes when dilute acid is added, it indicates the presence of calcium carbonate in the rock. When calcium carbonate reacts with acid, it produces carbon dioxide gas, which causes the fizzing.
A rock will always contain at least one mineral.
They all contain minerals.

It depends on what kind of rock they are made of. Cliffs formed of igneous rock generally do not contain carbonates. Cliffs that have some limestone, marble, or dolomite do contain carbonates.
