why does the oceanic crust sink beneath the continental crust at the subduction zone

Answers

Answer 1

Answer:

oceanic crust sinks because it is denser and has higher specific gravity than the more silicon aluminum enriched continental crust. What drives substitution is convection and conduction in outer core of earth, that heat , only a small part of which is due radioactive isotopes, has to make it's way to Earth's surface by both conduction and convection. Iron and nickel o have the highest specific gravities of the 10 most common elements in the Milky Way Galaxy. This is why oceanic crust sinks and is subducted continental crust has to have a lot more force applied before it inks, because it doesn't want to sink.

Answer 2
Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. (Sometimes, oceanic crust may grow so old and that dense that it collapses and spontaneously forms a subduction zone, scientists think.

What is theory of continental drift ?

The physicist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through seas and into one another, in the early 20th century.

Plate tectonics over millions of years produced continental drift. Additionally, plate tectonics clarified how the motion of the plates causes earthquakes and volcanoes, as well as how the collision of continents produced vast mountain ranges.

The fossil record is one sort of evidence that has been used to support the Theory of Continental Drift. In rocks with a comparable age, scientists have discovered fossils of related plant and animal species.

Explanation:

We can split this problem into a circle (since there are 2 semicircles) and a rectangle.

First lets find the area of the rectangle, 11*4 = 44

Now lets find the area of the circle = 4/2^2 * 3.14 = 12.56

Finally, we can add them together to get the total, 12.56+44 = 56.56 --> 56.6

He was not a failure

Explanation:

Columbus was searching for a route, but found something much greater than that that went on to benefit his homeland and many other European countries. Additionally, his initial belief of there being a western sea route to Asia was based on European maps at the time (they hadn't discovered the Americas yet, so they didn't know the path would be blocked). His trip was about discovering a new path, not traveling on one that already existed.

Volcanic ash causes airplane engines to fail, destroys crops, contaminates water, and damages electronics and machinery. The ash carpets the ground, burying everything, sometimes even causing buildings to collapse. 

What is similar about the desert and savanna zones in Africa?

Both experience limited rainfall.
Both contain abundant grasslands.
Both experience high temperatures.

please choose from above

Answers

Answer:

Both experience limited rainfall.

Explanation:

no water

The similarity between desert and savanna zones in Africa is both have high temperatures. Thus, the correct answer is option D.

What are savanna zones?

A savanna, also known as a savannah, is a mixed woodland-grassland ecosystem distinguished by trees that are sufficiently spaced so that the canopy does not close. The open canopy allows enough light to reach the ground to support an unbroken herbaceous layer dominated by grasses.

Despite their dense tree cover, savannas have an open canopy. Savannas are commonly thought to have widely spaced, scattered trees. However, tree densities are higher and trees are more regularly spaced in many savannas than in forests. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season.

Therefore, both experience high temperatures.
