NaCl is a highly ionic compound and if it dissolved in water will be heavier than most organic layers. This is called the brine layer in industry. This can now be decanted off from the bottom of a reactor or speerating funnel etc.

They formed as heavier and lighter rocks separated
gravity separated them by density, iron in the center water and gasses on the outside.
Sedimentary rocks are created when layers of debris are compacted and cemented together. These types of rocks are also known as secondary rocks because they often result from fragments of other rocks being cemented together. The type of sedimentary rock you seem to be asking about is organic. Organic sedimentary rock is formed when the sedimentary debris is compiled through organic processes. For example rocks forming as succesive layers of substrate pile onto one another and compact over time.
inorganic soil layers are layers of broken down rock that have become soil without the organic material (such as: leaves, grass, decomposed life forms) . The Bedrock and Parts of the Parent Material are inorganic soil layers.
chloroform is used to denature protein and settle it in the bottom during rna extraction ,also it helps to form organic and inorganic layers in which rna is dissolved in inorganic layer.
The ocean floor generally consists of basalt cooled from magma, and the overlying layers of sediment, both inorganic and organic.
Organic layers are part of the soil.
Coal
i have no ideas of what the answer could be sorry

Good question. Hopefully, there's frosting between the attached layers.
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks. They are different because organic rocks are composed of the remains of living things but chemical rocks are formed by inorganic processes such as evaporation.
a rock formed by unconsolidated sediment deposited in layers
Limestone
The layers got separated so the cd is no longer reading.
