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).
your answer is
A) the sunlight from the sun is concentrated in the smallest area of earth
Taiga is the largest Continental Biome. It experiences long, cold winter; short, mild summers; and low precipitation. It is characterized by Coniferous forests. It covers most of the Southern Hemisphere.
Answer:
Based on the solar light that enters the oceans and river
Explanation:
- River ecosystem of a couple of both biotic and abiotic components among the plants and animals involving there physical and chemical properties. As the flow of water is unidirectional, it's in state of continuous physical change and has a high degree of spatial and temporal heterogeneity.
- River sources are small, and in the areas of mountain streams, are steep and erosional. In temperate environments, overhead tree canopy conditions result in cool, well-oxygenated streams.
- All sorts of communities like coastal, estuaries, reefs and deep-sea trenches like Mariana trench which has no sunlight has a distinct type of community.
The answer is 2. The fact that mechanized agriculture has replaced manual labor. Hope this helps :)
