The b horizon is also called the a. topsoil b. subsoil c. partially altered parent material d. unaltered parent material

B. subsoil

Explanation:

A soil horizon can be define as the parallel layer of the soil which differs in texture, color and composition based upon the physical, chemical and biological activities. A typical soil horizon varies from layers above and beneath. The B horizon is called as a subsoil. It is typically comprise of high inorganic mineral density. It is developed by the process of pedogenesis. The inorganic minerals such as iron oxides, and clay are predominately present in this horizon. It is typically reddish to brownish in color due to high concentration of iron oxides.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
