Biology
1 answer:
GenaCL600 [577]3 years ago
8 0

Answer:

The correct answer is option B. "It disrupts a larger area and produces less oil than drilling".

Explanation:

Oil extraction from tar sands is an inefficient way of extracting oil from a mixture of oil, sand, clay and water. The oil extraction from tar sands requires a considerable amount of energy and water and generates more pollution than oil drilling. Another downside of this process is that it disrupts a larger area and produces less oil than drilling. It is estimates that to produce one barrel of oil, 2 tons of oil sand should be processed.

The cohesive attraction or cohesive forces is the action or property of like molecules which stick together.

It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.

Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.

Hence, the force that is present between two water molecules is cohesion.
