No,fossilsare just the impressions of an organism engraved on geologic material (rock, sediment, resin etc). Scientists useradiometric datingto date these types of materials.
Slate can be used for blackboards, roofing and floors. When you crush it, you can use it flooring and paints.
Magma can use cracks that are already there on it way to the surface. If there are no cracks present, the magma can create them.
it can be split into thin, flat layers
smooth in some places but quite rough in others. depends on where it has been lying.
It can be green red black gray brown and yellow. People use it for Oil or natural gas. Shale is the parent rock of Slate. Used for brick ,tile ,pipe ,pottery ,and others.
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.
No, being crystallized from liquid magma there are virtually no pore spaces so it has a low porosity and fluids can not flow through it very easily. However granite usually has lage open joints in it (a result of the shrinkage during cooling) and these do allow water to flow.
Slate is formed by the effects of heat and pressure on the rocks shale or mudstone. The source of the heat and pressure is usually from depth of burial or tectonic plate collisions, where shale is put under tremendous directional pressure. The pressure causes an alignment of the constituent minerals in the shale, creating a foliated or platy texture, characteristic of certain metamorphic rocks.

he finally wiped the slate clean
With all the research I have done, I am pretty sure that you can use slate cleaner on marble.
Some artists use old slate shingles for a canvass. The Slate Lady even sells them--see link.
slate is something you use fo the roofs of some houses
It's called a "clap slate," a "clapboard," a "production board," a "production slate," a "scene slate," a "film slate," or just a "clapper."

The scientist was determined to get some magma to use in his research. Magma is the hot fluid that is in the Earth's crust.
