The ocean once covered most of the land, so when fish or sea life died and the ocean (after a few millions/billions of years) receded to where it is today, their remains were left underneath the soil.
in pores or holes in the soil and the underlying rock layers

No, it is called ground water.
The deeper you get into the earth, the more weight you have above you. This results in pressure that increases the density of the material below.
There are five basic layers of the Earth, being the crust, upper mantle, inner mantle, outer core, and inner core. Of these, the lithosphere is composed of the crust and upper mantle, and the asthenosphere is part of the mantle, below the lithosphere.

Permanently frozen layers of soil are known as permafrost. Permafrost is soil, sediment, or rock that remains at or below 0°C for at least two consecutive years. It is mostly found in polar and high-altitude regions.
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
The ocean is stratified with denser layers below less dense layers.
The temperature in the zone beneath the thermocline remains relatively stable as it experiences minimal mixing with the warmer water above and the cooler water below. This results in a sharp temperature gradient between the layers above and below the thermocline.
The temperature of soil below the frost line remains fairly constant throughout the year, typically around 50°F (10°C). This is because the soil at that depth is insulated from surface temperature fluctuations by the surrounding layers of earth.
Due to faulting or folding.
layers are separate images stacked one above another, layers can have transparent areas so you can see content below
Water drains away (land contour changes, sea level changes) mud turns to dirt,' grass
Basically Layers are pictures stacked one above another, Layers supports transparency so you can see what is below. See related link below answer.
Layers are pictures stacked one to another, Layers can contain transparent pixels so you can see through Layer above what is on Layer below.
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
