I believe you may be talking about Mica
Slate has a smooth, fine-grained texture with a slightly rough surface due to its layered composition. It is typically dense and resistant to scratching, making it a popular choice for flooring and roofing materials.
Basalt feels like a smooth, dense and cool stone.
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.
Compaction is a critical part of the lithification process for sedimentary rocks, especially for fine-grained sediments like clay and silt. It involves the reduction of pore space by the weight of overlying layers, leading to the grains coming closer together and forming a solid rock mass. Compaction helps in transforming loose sediments into coherent and hard rocks like shale or mudstone.
Basalt is a relatively heavy iron rich hard rock.

Slate is a type of metamorphic rock that is generally hard and dense. It has a smooth, fine-grained texture and is often used in construction for things like roofing tiles and countertops.

Yes, they can. Not just gymnasts can do the splits, anyone who is very flexible can do the splits if they practice hard.
Hornfels typically feels hard and dense, with a fine-grained texture. It may have a slightly rough or granular surface due to its fine interlocking crystals. It can feel smooth when polished.
There are various types of maple and pine each with its own characteristics but the main difference in characteristics is that maple is hard and fine grained whereas pine is relatively soft and coarse grained. There is a list of various types of wood and their characteristics at `Properties and Uses of Woods' - http://www.inquirewithin.biz/Vol1/Woods/wood_properties.htm.
Hard mudstone is a sedimentary rock composed mainly of clay and silt particles that have compacted together over time. It is characterized by its dense and impermeable nature, making it resistant to weathering and erosion. Hard mudstone often has a fine-grained texture and can appear as dark gray, black, or brown in color.
It can be described as aphanitic. This just means that the rock has very small, hard to see crystals. The crystals do not have time to grow large when they are exposed to the air so they cool quickly and remain small. If water is added to the melt, the texture can be described as glassy (like obsidian).

first you haft to be a good strecher doing the splits is very hard it can be very pain full if i was u i would go to a gymastics place
Yes, slate is a strong and durable material that is commonly used in roofing and flooring due to its resistance to impact and wear. It is also known for its ability to withstand extreme weather conditions.
When dirt gets into layers and then it hardens and becomes hard like a rock.
