Slate and shale have the same make-up. Slate is formed from sedimentary shale by pressure and heat. Wet shale has the same smell that wet slate has.
The answer is Slate. It is similar to Shale. It is still used but much less than 80 years ago. Slate is used in upscale roofing applications.
Marble and slate are both used by humans in buildings. Marble is used to make a number of items such as flooring and countertops. Slate is used primarily for roofing shingles.
The metamorphic rock slate.
Many kinds of rocks both of igneous and sedimentary nature eg; Limestone (sedimentary ) to marble or granite or diorite (igneous) to gneiss.
Slate (Silicon Dioxide) in fine grained form, the same sedimentary rock they used for old house roof slats
Wood, slate, metal sheet, asphalt shingle, concrete shingles, rubber membrane, fabric, baked clay tiles.
The material used to make the shingles on a roof determines how often a roof needs to be replaced. For example, barring damage from extreme circumstances, slate shingles will probably last the entire lifetime of a house, where as asphalt shingles will probably need to be replaced every 15 to 30 years.
all im gonna say is " you dont "but you can make things out of slate.
== == == == == == The cap rock on a coal bed is usually a sedimentary rock, (i.e. shale sandstone etc.) but not always shale. Slate is a metamorphic rock, usually derived from shale that has been exposed to high pressures and temperatures over very long periods of time. Ways to tell the difference between slate and shale: Slate will have a smooth surface, and possible have light glare at a right angle. Shale will have a dull, sandy surface. Tap them against something hard. Slate will make a "clink" noise, almost like porcelain or ceramic, where shale will make a "thud" sound. Rub it against your teeth. Slate will be smooth, shale will be gritty. == == == ==
Slate, which is a flat rock somewhat similar to shale but with a very distinct difference. Shale would actually make a disastrous roof, especially in rainy climates as it tends to become soft and mudlike when it gets wet. Slate, on the other is a thin layer of very hard rock through which rain cannot penetrate and makes an excellent roof.
Slate rock is normally used for roof tiles etc.
