Plasma Membrane (the skin)
A disk containing cell wall material is called a cell plate. It forms during the plant cell division process to help separate the two daughter cells.
The spongy material containing waterlogged mosses and plants is called peat. It is formed over time as dead plant material accumulates in waterlogged environments with limited oxygen, leading to the partial decomposition of organic matter.
It is called fossilization or petrification. This process involves minerals replacing the organic material of an organism, resulting in the preservation of its structure in rock.
This process is called fossilization. Minerals from the surrounding rock infiltrate the bone structure, gradually replacing the organic material with minerals such as silica or calcite, turning it into a fossil.
A rock containing minerals is called an ore.answ2. A Mineral is defined as "A naturally occurring, homogeneous solid, with a defined chemical composition and a highly ordered atomic arrangement."An Ore on the other hand, is "A metalliferous mineral or aggregate of metalliferous minerals mixed with a gangue (unwanted material) and that can be exploited at a profit."
These are known as silicate minerals or silicates.
Rock material mined for its constituent elements or minerals is called "ore."
A rock containing two or more minerals is called a "polymictic rock."
I am a student and currently studying weathering, an example is Iron-containing minerals like magnetite, can weather to from a rust-like material called limonite.
Digging out minerals from the earth is called mining. Mining involves extracting valuable minerals or other geological materials from the earth's surface or beneath the surface.
Natural hot water containing many minerals and found on the surface of the earth is called a hot spring.

Silicates
Minerals containing silicon, oxygen, and one or more elements are called silicates. Silicates are the largest and most important group of minerals, making up approximately 90% of Earth’s crust. Examples of silicate minerals include quartz, feldspar, and mica.
Minerals that contain metallic elements are called ores. These ores are valuable natural resources that can be mined for the extraction of the metallic elements they contain, which are often used in various industries such as manufacturing and construction.
Minerals mined for their economic value are called ores.
