a)Soilprofile

b)Neutralsolutions

c)conductorsofheat.​

Answer 1

Answer:

a) soil profile: Soil profile is defined as the vertical section of the soil from the ground surface downwards to where the soil meets the underlying rock.

b) neutral solutions:  a solution in which the concentration of hydrogen ions and hydroxide ions are equal.

c) conductors of heat: a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself.

Answer 2

Answer:

a) A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D. Most important for plant growth, the A and B horizons are the top two layers of the soil.

b) By definition, a neutral solution is a solution that has a pH of 7. It is neither acidic (pH < 7) nor basic (pH > 7), but right in the middle, or neutral.

c) In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor heat conductors.
