They are both made with the same substance but the topsoil has newer soil than the subsoil.

yes
by the way there are sunlight in human and in soil. ************ Topsoil will contain more humus (notice the spelling!) than subsoil. Topsoil is the layer where most household gardening and food production on farms takes place. The subsoil could be solid clay, which would make the topsoil rather wet after a heavy rain. Or even solid bedrock, with a thin layer of topsoil on top - not really suitable for growing deep rooted plants.
The subsoil harbors many micro-organisms. Metabolic activities of these living objects provide nutrients for plant growth. Hence subsoil is considered as an important entity for vegetation.

The ground which lies between the topsoil and earth's crust is known as the subsoil and comprises particles of weathered rock of various shapes and sizes. It is usually necessary to provide a level surface from which construction may take place, and this level may be lower than the top of the subsoil. In such cases, excavation into the subsoil is required to reduce the level of the ground. The volume of subsoil to be excavated, together with the nature of the material, will determine the type of machine and methods to be used.
