What are coal beds?
A layer of coal under the ground is sometimes called a coal bed.
What geologist wants to locate a horizontal coal bed on a soil-covered slope where soil creep is active A distinctive sandstone bed underlies the coal bed On the basis of weathered sandstone fragm?
A very dumb one.
What is the arrangement of sedimentary rock unit names from largest to smallest?
Group, formation, member, and bed.
Why is coal an unusual sedimentary rock?
First of all coal is not an unusual sedimentary rock, it is very abundant for the time being. The following is a tutorial from the supplied web site: Coal is clearly made up of lots of compressed bits of dead plants. But when we walk around in the world we usually see old bits of wood and leaves decaying and rotting away (that is, getting eaten by bacteria, insects, and all sorts of organisms involved in decay and recycling of organic matter). For thick layers of plant stuff to get fossilized as coal, something must be going on. Coal Formation starts with accumulation of organic matter (bits of dead plants) in a low oxygen setting such as a peat bog. The organic matter accumulates and forms a bed of peat. The peat bed gets buried by other sediments and under heat and pressure begins to transform to a low grade coal - a Lignite. More heat and pressure further metamorphose the lignite into Bituminous coal. Even more heat and pressure metamorphose the bituminous coal into a nice hard shiny Anthracite. Coal is usually classified into three grades: Lignite, brown coal; Bituminous coal, soft coal; and Anthracite, hard coal. Anthracite is dense, nice and hard, and shiny. The first step in the formation of coal is the accumulation of plant debris in low oxygen conditions, such as in this damp low spot on a moor. Peat exposed to heat and pressure from burial beneath other sediments becomes compressed and chemicaly changes into low grade coals such as this lignite, and under further heat and pressure is converted to higher grade coals. The pressure from overlying sediments that bury a peat bed will compact the coal. Peats transform to low grade lignites when they are compressed to about 20% of their original thickness. Lignite typicaly transforms to bituminous coal as it is compressed further and heated to between 100 and 200°C. This drives much of the water and other volitiles from the coal. Longer exposure to elevated temperature will further drive volatiles from the coal, and drive chemical reactions that produce anthracite. Anthracite coals are typicaly compressed to 5-10% of the orginal thickness of the peat bed, and contain less than 10% water and other volatiles.
Why is bed rock called the parent of soil?
Bed rock is called the parent of soil because soil formation begins when bed rock is broken down by weathering . Weathering breaks the parent rock into smaller and smaller peices later on the weathered rock is broke down into soil particles. :-)
How do plant fossils and bed of coal support the idea that Antarctica once was warmer that it is today?
Plant fossils and coal seams could only have formed if Antarctic had once been warmer (further north).
Does coal oil same as fossil fuels?
I believe you mean coal bed gas or coal bed methane which is a fossil fuel.

Where are groundhogs found?
Groundhog's are ususally found in tropical rainforests and in Antarctica. Sometimes they are found under your bed.
What causes clinker formation in boiler?
Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers to be miserable stuff

How much coal dust can be fed to the fluidized bed combustion furnace through 4 Inch size and 6 Inch size Under Bed Coal feeding nozzle?
Assuming the measurements are correct then I would guesstimate that that would be the exact size required.
