Geography is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of the Earth and planets. The first person to use the word γεωγραφία was Eratosthenes.
If we have a dark colored, coarse soil and reddish smooth soil for comparison, we can find lots of differences in them.
- The dark soil will have bigger layer of humus, while the reddish one will have a very small almost unnoticeable layer of humus.
- The color differs a lot, while the dark soil will have a dark brownish color, the reddish one will have intense orange-red color.
- The vertical profile of the soils will differ a lot; the dark one will have much bigger top two layers, while the reddish one will have very small upper layers and dominant middle layer.
- The dark soil will be rich in biomass, while the reddish one will be rich in iron and clay.
This is correct. Even the basic scientific theories get tested and checked time after time after time. The most basic example would be that people once thought the Earth was flat and now it changed and they believe it is round.
