<span>"Village" is the term used to refer to the first settlements formed as humans began domesticating plants and animals.
A village is comprised of a clustered human settlement or community, with a few hundred to a few thousand people. It is typically smaller than a town but larger than a hamlet and is usually a permanent settlement, with dwellings spaced closely from each other. The surrounding lands were usually farmed, but in the case of traditional fishing villages, they were located adjacent to fishing grounds as well. </span>
The remains of fossils give scientists clues as to what the world may have been like a long tome ago. If fish fossils are found on the side of a mountain, there may have been a lake there. If a skeleton is found, they can decide what creature it was.
Consequently plant roots will get more moisture with less effort. It also improves soil structure due to alternate drying and cooling and soil aeration which helps in multiplication of micro-organisms. This is the reason that farmers plough their field during summer. These are reasons why farmers plough their fields during the summer.
Hope this helps! :3
