Answer:
The correct answer will be- Crop rotation
Explanation:
When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.
Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.
The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".
Thus, crop rotation is the correct answer.
The major ingredient of scientific argument is scientific evidence and known science concepts. Thus through scientific idea, expectations and observations a scientific argument is given birth to. Scientific argument are usually arrived at by mean of scientific methods.
The smoke increases effectively increasing the planetary albedo, forcing is less however and tends to be insensitive to the solar geometry
It will be Control. Part of the experiment used to show that the results of an experiment is really due to the conditions being tested.
