Most Shales are hard.
Yes, slate is harder than shale. Slate is a fine-grained metamorphic rock that is formed from the compression of shale, resulting in a more durable and stronger material. Shale, on the other hand, is a sedimentary rock formed from the accumulation of clay and other mineral particles.
It depends on how you are defining the word 'soft'. Quartzite is the hardest and most durable of the three - no question there. Shale can be crumbled with the tap of a hammer. Some loosely cemented sandstone can be crumbled when squeezed hard enough with your hand and some is well cemented and quite hard.
Brick is not typically considered a raw material. It is a manufactured product made from clay or shale that has been fired in a kiln to form a hard, durable building material. The raw materials used to make bricks are the clay or shale itself.
A material that contains hard-to-mine petroleum is oil shale. Oil shale is a sedimentary rock that contains kerogen, a solid organic material that can be converted into synthetic crude oil through processes like pyrolysis. Extracting petroleum from oil shale is more challenging and costly compared to conventional oil extraction due to the need for extensive heating and processing. As a result, while it represents a significant potential resource, its economic viability often depends on oil prices and technological advancements.
Yes, slate is harder than shale. Slate is a fine-grained, foliated metamorphic rock that has undergone more intense heat and pressure than shale, a fine-grained sedimentary rock. As a result, slate is more durable and resistant to erosion compared to shale.

No, you generally cannot scratch shale with your fingernails. Shale is a sedimentary rock that is relatively hard and composed of clay minerals, making it more resistant to scratching. Fingernails have a hardness of about 2.5 on the Mohs scale, while shale typically has a hardness of around 3 to 4. Therefore, a fingernail would not be able to leave a scratch on shale.
Shale is a noun.

It can be. It is found in a rock type called shale and is produced in the shale form the original bio mater included in the deposition of the shale. If a unit of shale lithology is to be found on the continental shelf strata then it is likely that that shale will contain shale gas and it will be under the sea.
The Shale is not a metamorphic rock it is a sedimentary rock.
No, shale is clastic.
Shale.
No, shale is not magnetic.
Another name for shale is mudstone
Shale rocks turn into clay. The pressure make shale into clay.
Melanee Shale's birth name is Melanee Ann Shale.
