The ground is for the vast majority of Spanish-speaking countries synonymous with floor, which means the place under our feet and that we step on.
In Spain, the differences between flat and ground become even more indefinite, since they call the apartments flat, for example, I live in a flat.
The surface part of the natural earth’s crust is called soil or humus, which differs from the concept of earth, since earth includes the soil, resources, structures and processes of the entire emerged surface of planet Earth.
The soil or humus (the upper part of the soil) is the mantle that covers the planet; it is composed of a mixture of disintegrated rock and organic matter in constant decomposition and renewal.
The floor is a horizontally flat surface, created by man and for his use. There are floors made of all materials such as wood, cement, tiles, mosaics, among others. The floors are generally framed in an architectural space.
It is important to be aware of the difference between the floor and the ground when we think that we live on a floor and that below it is the ground that houses the great diversity of living beings that we know and all those that we never knew or will know.
