Is shale an element?

Shale is not an element. Shale is a type of sedimentary rock composed of clay-sized particles that have been compacted over time. It is made up of various minerals such as quartz, feldspar, and clay minerals.


What is found on top of coal slate or shale?

== == == == == == 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. == == == ==


What is a rock that yields oil when heated?

Oil shale is a type of rock that contains kerogen, a precursor to oil. When heated, the kerogen in oil shale can be converted into oil and gas. This process is known as pyrolysis.


Is an wedge shattering a slab of shale a physical or chemical change?

The wedge shattering the slab of shale is a physical change. This is because the shale undergoes a change in shape and size without any new substances being formed.


What happens when oil shale burns?

When oil shale burns, it releases heat and produces carbon dioxide, water vapor, and other combustion byproducts. The heat generated can be harnessed for energy production through combustion or other thermal processes. Burning oil shale can also emit pollutants and greenhouse gases, which can have environmental and health impacts.
