How do volcanic eruptions at divergent boundaries affect deep ocean currents?

2 answers:

5 0

The speed and violence of the tectonic processes are different.

Divergence is slower and somewhat gentler, and there is less restricting pressure to oppose the upwelling magma (Water may be heavy, but it IS fluid.) The fluidity and cold temperature of the ocean absorb and dissipate the violence of forcing magma out of the mantle and the encounter between great heat and cold waters.

Convergence may combine tectonic movement from multiple vectors, different types of plates may force an oceanic plate under a continental plate and the collision speed will determine the subduction angle and depth. The ejection of material from great depth, through an overriding solid plate, requires great force and pressure. Where hot material encounters underground waters, resultant steam may be superheated and compressed.

Note, however, that volcanic eruptions resulting from deep underwater hot spots may be the most violent of all such events, belying the question’s premise.

Hope this helps :)

After the volcano eruption, evaporation over ocean becomes lower, because it is largely determined by the ocean skin temperature change. The quick response of evaporation to the surface cooling and the delayed response of river runoff to the associated lower precipitation lead to an increased sea level.

Leona [35]

Answer:

Explanation:

Scientists have been able to determine that the melting of ice from Greenland ice sheet will reduce the rate of Atlantic Meridional Overturning Circulation (AMOC) which is an important part of the global ocean current that determines the climate and controls Gulf stream. It as been inferred by researchers that this could affect climatic conditions in places like Europe and North America in the future.

The influx of fresh water from Greenland which is made up of runoff from ice, tundra and ice discharge will weaken the AMOC and this as both local and global effects on climate.

How did the earthworm's mode of location compare to the nematode's mode of location?

lesya [120]

Answer: The earthworm contracts and extends in its movement, but the nematode moves side by side.

Explanation:

NOTE: By mode of location, we mean the way it moves.

The skin of a nematode is very unusual in that it secretes a thick outer cuticle which is both hard and flexible. And this cuticle makes it sustain a side by side mode of location. The closest thing a roundworm has to a skeleton is its cuticle and it uses it as a support and balance point for movement. Long muscles lie just underneath the epidermis and are all aligned longitudinally along the inside of the body, so the nematode can only bend its body from side to side, not contract or extend itself.

Whereas the earthworm extends and contracts as its mode of location.

An earthworm moves by using its two different sets of muscles: circular muscles for looping around each segment, and the longitudinal muscles for running along the length of the body.

The contraction of the circular muscles make the earthworm stretch becoming longer and thinner. The earthworm uses its longitudinal muscles to contract and thus becomes shorter and wider or it bends from one side to the other, pulling the body forward in the process. The earthworm withdraws the front setae and uses its rear setae to anchor itself at the back. Then the earthworm uses its circular muscles to lengthen and push itself forward again.

In Ontario, what type of land use should be given priority: agriculture, recreation, conversion, or residential usage? Explain w

Nana76 [90]

Answer:

Residential land use should be given priority in Ontario.

Explanation:

Ontario is the most populous province in Canada. Its approximately 15 million inhabitants make up 40% of the country's total population. Within the province is Toronto, the most important city in Canada, as well as Ottawa, the national capital, and other important cities such as Hamilton or London, among others.

Ontario is, in essence, Canada's economic engine. Its largest production is industrial, with different industrial and technological poles spread throughout the province. For example, in the city of London, the main industry is automotive production, while in Hamilton there are a large number of steel industries. Not minor are the energy, banking, financial and even agricultural industries in the province.

All this enormous production makes more and more labor want to move to the province, so it is necessary to expand the residential areas in order to receive all these workers and thus facilitate the expansion of Ontario's economic production.
