humus
Peat is decayed vegetation found in bogs. The main component is sphagnum moss, but it contains other plants as well. Peatlands are sometimes called mire.
Coal
Twenty grams would be considered the mass of the rock, which is a measure of the amount of matter it contains.
the layer in the earths suface that contains liquid rock is called: the inner core (mainly)\ outer core (some) and (parts) of the mantle.
The upper part of the mantle, known as the asthenosphere, contains molten material. This region is partially molten, allowing for the movement of tectonic plates. Deeper parts of the mantle, such as the lower mantle, contain solid rock due to higher pressures and temperatures.
weathered rock,decayed organic matter,water and sediments.
Mold
A fossil type characterized by an open space left inside a rock by an organism that has decayed is called a mold fossil. Mold fossils are created when the organism decomposes and the impression is preserved in the sediment that surrounds it, leaving behind a cavity in the shape of the organism.
compaction and cementation are the only parts of the rock cycle that cannot be observed.
Coal is an organic sedimentary rock, formed from the sedimentary processes of compaction and cementation.
The layer that contains liquid rock is the mantle, which is located beneath the Earth's crust. Magma, which is molten rock, can be found in the mantle and can sometimes rise to the surface through volcanic activity.
A type of rock? Possibly coal, which is decayed plant material, compressed and turned into a 'rock-like' material.
