Is slate smooth?
yes
Is slate hard soft or smooth?
Slate is a hard and brittle rock.
Why do rocks have a range of different appearances?
Some weathering processes simply fracture rocks, producing jagged fractures. Other weathering processes abrade or chemically dissolve the rock surface, producing smooth surfaces. Some rocks fracture along planes of weakness producing fairly smooth surfaces, like shale, or slate; other rocks fracture jaggedly, without orientation along planes of weakness, like granite.
Are slate and gneiss foliated?
Slate is certainly foliated and splits easily along this foliation surface. Gneisses frequently banded and this banding is also a foliation.
What is the hardness of slate?
Slate is a rock of mixed mineral composition and does therefore does not possess a uniform Mohs hardness. Because of varying porosity along with other factors, the elastic modulus, or measurement of stiffness, of various slate specimens will vary.
Which is the splitting of a mineral along smooth flat surfaces?
Slate is a sedimentary rock that can be split horizontally to produce smooth flat surfaces that is often used as a roofing material.
What is the luster for slate?

What type of texture does slate rock have?

Why is slate an excellent material for pool and billiard tables?
The major advantage of a slate bed pool table is that it provides a more true and even run of the balls. On other surfaces the balls are more likely to deviate from straight lines. Slate tables will also allow the balls to react better to spin.
What kind of solid tends to break along straight lines?
Slate splits into sheets and is used on roofs.

What does slate look and feel like?
Rough when it is fresh but when shaped it is smooth and cold. Slate is used as chalkboards. It is smooth, cool or cold to the touch, and chalk can leave 'marks' so humans can write or draw on its surface. Slate has been used for centuries in school (students used a single small "slate" to do their "figuring" -math- and to write words or sentences.
When somebody says a rock has perfect cleavage what does that mean?
That means when you break it it will form a smooth flat surface. Slate has near perfect cleavage so it's used to make pool tables and blackboards.
