Answer:

Option (C)

Explanation:

Sea-floor spreading refers to the splitting of the ocean floor thereby leading to the expansion of the seas and oceans. This process adds new materials to the ocean floor along the mid-oceanic ridge. This idea of sea floor spreading allowed the scientists to demarcate that the rocks that are present along the mid oceanic ridge are the younger and the rocks that are present away from the rocks are the older rocks.

Along the mid-oceanic ridge, the rocks are comprised of magnetic strips that shifts their orientation every time it erupts. This separation of sea floor takes place due to the plate tectonic movement. It generates earthquakes of various intensities in the subduction zone. The rocks of the oceanic crust are basaltic in nature and are very dense compared to the continental crust.

Thus, the correct answer is option (C).

In the past five years, 30 percent of the worlds newly discovered oil reserves have come from

Anna11 [10]

Oil reserves are the amount of technically and economically recoverable oil. Reserves may be for a well, for a reservoir, for a field, for a nation, or for the world. Different classifications of reserves are related to their degree of certainty.
The total estimated amount of oil in an oil reservoir, including both producible and non-producible oil, is called oil in place. However, because of reservoir characteristics and limitations in petroleum extraction technologies, only a fraction of this oil can be brought to the surface, and it is only this producible fraction that is considered to be reserves. The ratio of reserves to the total amount of oil in a particular reservoir is called the recovery factor. Determining a recovery factor for a given field depends on several features of the operation, including method of oil recovery used and technological developments.[1]

Which of these are the two major sources of nitrate pollution in rivers? the burning of fossil fuels by factories and cars anima

Mekhanik [1.2K]

Answer:

animal wastes and fertilizers

Explanation:

The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.

Why is it cyclones are given female names?

Allisa [31]

I did some research, and I found this: "Since 1953, US started using female names. The practice came to an end in 1979 when the US Natural Weather Service and the World Meteorological Organisation developed a systematic way of naming cyclones in the beginning of the year, alternating male and female names, arranged in an alphabetical order."
Hope this helps you, and happy studying~!
