Answer:
To allow the proper amount of water to be passed through to other communities.
Explanation:
Answer:
Nanotechnology helps to improve viscous fingering and the nano-particles can transmit through nanopores of sandstone which helps to increase the recovery by decreasing the surface tension between oil and water. The pore spaces are very fine so water molecules cannot penetrate through all of them in order to push the oil. This is why the nano-particles such as iron (Fe) and Silicon (Si) are used with distilled water. These particles can easily move through the interconnected pores and thereby pushes the oil to move out of it. It is a widely accepted concept in Enhanced Oil Recovery (EOR).
Physical weathering is most active where temperature and rainfall are both. low. Chemical weathering is most active in regions of high temperature and rainfall. Most world. regions experience a combination of both physical and chemical weathering.
Hope of gaining a better standard of living
Due to the adverse conditions of poverty and unemployment in the rural areas, people migrate to urban areas. In urban areas they find increased employment opportunities and better living conditions.
