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.

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

Both contain stone plateaus.
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.

Porosity

Explanation:

The void spaces in soil which can be filled by water or air is porosity. Porosity is the percentage of space or volume of void within a rock or soil.

Porosity is based on the pores within soil. Pores hold fluids which are very important for living organisms that depends on the soil. Also, the porosity and permeability helps to know the dynamics of water flow within the subsurface. Permeability is the interconnectivity of pore spaces within the soil.

A. 600 m/km
B. 1,333 m/km
C. 750 m/km
D 500 m/km

Answers

Answer:

750 m/km

Explanation:

If the map scale is 1 cm = 0.5 km, then a 1.6 cm line will represent 0.8 km. The elevation change is 900 - 300 = 600 meters. The gradient is the elevation change divided by the distance, so 600 m/0.8 km = 750 m/km.

Answers

Answer:

On the side of Earth facing the moon.

Explanation:

As moon's gravitational pull is responsible for high tides.

hope it helps!

The high tides occur on the side of the Earth facing the moon. Therefore option B is correct.

What is Tide?

Tides are extremely long-period waves that travel across the water as a result of the moon's and the sun's gravitational pull. The rise and fall of the sea's surface on a regular basis is what tides, which originate in the ocean, appear as they move toward the coastlines.

The two primary causes of high and low tides are the Earth's rotation and the moon's gravitational pull on the planet. The Moon's pull is greatest on the side of the Earth nearest to it, and as a result, the oceans rise, and high tides are produced.

The majority of shorelines see two high tides and two low tides every twenty-four hours, however, certain places only get one of each. The physical characteristics of a coastline, such as a long, sandy beach or a rocky cove, as well as the depth of the water immediately offshore, influence the height of the tides.

Therefore option B is correct.
