When did rock layer h form relative to the other rock layers? in your answers, compare layer h to as many rock layers as you can.

Halitic rocks have a large mineral layer of evaporite sedimentary rock, which is produced from drained lakes, playa and closed seas.

The difference between Halit rock layers and other rock layers is the element in it. The element in the Halit rock layer is sodium chloride.

Halit Rock Layer is a type of salt, a mineral form (natural) from sodium chloride (NaCl) or better known as rock salt.

Knowledge about the layers of soil and rocks on the surface of the earth is stratigraphy. Stratigraphy is the study of the history, composition and relative age and distribution of bedding layers and the interpretation of rock layers to explain the history of the Earth.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
