The top soil would most likely be thicker in lush tropical area.
Explanation:
The top soil presents just above the earth's surface in the upper position of soil profile. It's thickness is 2 to 3 inches. Tropical area receives highest rainfall and direct sunlight which promotes the growth of lush vegetation that tightly holds the soil.
Dry region is devoid of vegetation. And it is free zone for air passing. With high speed wind top soil blow out from the upper surface and make surface bare. The thickness of soil in tropical area is maximum and pure.

Answer: Option (a) is the correct answer.
Explanation:
Ionic salts are defined as the salts which tend to contain ionic bonds as there occurs transfer of electrons between its combining atoms.
So, when an ionic salt melts or it is dissolved in water then it will dissociate into its respective ions and as electricity is the flow of electrons or ions. Hence, this salt is then able to conduct electricity.
As covalent compounds are insoluble in water so, they do no dissociate into ions. Hence, they do not conduct electricity.
Similarly, metallic and network solids do not dissociate into ions either when melted or dissolved in water. Therefore, they also do not conduct electricity.
Thus, we can conclude that when a white crystalline salt conducts electricity when it is melted and when it dissolves in water then this bond is of ionic type.
Mass is the amount of matter in an object. Density is the degree of compactness of a substance
Shorter I believe, but I would consult with your notes.
