Answer:
They are produced from rocks (parent material) through the processes of weathering and natural erosion.
Explanation:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Answer: A strong acid like HCl dissociates completely in an aqueous solution.
By definition a strong acid is that that dissociates completely in aqueous solutions. That means that all the molecules of the acid will be inoized into hydronium cation (H3O+) and anion (the negative radical).
For expample, HCl is a strong acid because
HCl + H2O----> H3O(+) + Cl-
The forwar arrow indicates that all the molecules of HCl reacted with the water for form the ions.

It's a weak bond between 2 molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other
Soil is usually layered. The uppermost layer is called topsoil and this layer contains the most humus, plant roots, and living creatures. The middle layer is called subsoil.
