Which type of material becomes molten rock at subduction zones? Light plates, heavy plates, continental crust, or new oceanic crust

Answers

Answer 1
The answer is heavy plates.

Let's look into the options one by one

Light plates- this is incorrect.

Light plates will stay above the denser plate when subduction occurs. Although the rock of crust mightbe bended, it will not be subducted under and reach magma and is therefore false.

Heavy plates- this is correct.

Heavy plate is the plate that will be pulled under the less dense plate due to gravity. When the plate reach the magma and can no longer maintain it's solid structure under the heat, the melts and becomes molten rock.

Continential plates- this is incorrect.

Continential plates is a place with less density and is lighter comparing to denser oceanic plate,thus it would not be the plate that subducts under another but the one to stay above, therefore it would not become molten rock.

New oceanic crust- this is incorrect.

The crust that are near subduction zones are usually the oldest crust that gets pushed aside to the zone,while new plate are usually the furthest away from the zone and is therefore not correct.

Answers

Answer:

European, African, Native American

Explanation:

This is because of the history of the region. The Europeans during their exploration (remember Christopher Columbus?) discovered this new continent and settled down. Farming was their main economic activity at the time. Because they needed cheap labor, they engaged in slavery by importing slaves from Africa to work on the farms. The interaction between the two races is attributed to the current race in South America. Native Americans due to their close proximity have also interacted with the races in these regions.

If Earth was not tilted on its axis, what changes would you expect to see in the seasons?

Summer would last much longer than winter.
Winter would last much longer than summer.
Temperatures in summer and winter would be more extreme.
Temperatures in summer and winter would be very similar.

Answers

If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant. so the seasons would be similer.

Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and went extinct during the late Permian period (248 million years ago). On another site, the scientists find ammonites. Ammonites lived during the Mesozoic Era (245 to 65 million years ago) and are not found after that period. What can be concluded about the rock layers? Choose all that apply.

The rock layers must have formed at the same time because they both contain biozones.


The rock layers must have formed at different times because they contain two different biozones.


The rock layer containing the trilobites must have formed before the one containing the ammonites.


The rock layer containing the trilobites must have formed after the one containing the ammonites.

Answers

The answer is; The rock layers must have formed at different times because they contain two different biozones

The rock layer with amniotes formed later after the rock layer with trilobites. This is beaus the former layer is younger in age than the latter layer. The ages of rocks is determined by absolute dating.


Answer:

The rock layers must have formed at the same time because they both contain bio-zones.

Explanation:

Trilobites are the extinct marine arthropods form an earlier know group of fossils and they have flourished through the lower Paleozoic era and during the Devonian periods, all of these trilobites were dried out. And ammonites are a molluscan animal that appeared in shell shapes in the Devonian periods and got extinct in Paleogene extinction. The fossil records of the trilobites show that they originated in present-day Siberia, and the ammonites lived in the open seas and thus were found in the rocks that were found in the bottom-dwelling conditions.

What happens to the density of the layers as you move from the crust to the inner core? Which layer is the densest?

Answers

The layers will be denser as you move from the crust to the inner core.

The density are as the following:

crust (2.55 g/cm³)
upper mantle (3.9 g/cm³)
lower mantle (5 g/cm³)
outer core (11.05 g/cm³)
inner core (12.95 g/cm³)

Thus we can also see that the inner core is the densest layer.

Which of the following effects would not likely result from enacting a free trade agreement? A. Imports would increase. B. Exports would increase. C. Prices of goods would decrease. D. Quotas and tariffs would increase. Please select the best answer from the choices provided.

Answers

Answer:

Option D.

Explanation:

Quotas and tariffs would increase, is the right answer.  

A free trade agreement indicates the agreement between two or more nations or countries that facilitates the import and export of commodities without restrictions. Under the free trade agreement, the countries involved in an agreement to sell or buy goods and services across the international border. The primary motive of this agreement is to increase export and import among member nations. A free trade agreement will result in all of the given options except D.

The effects that would not likely result from enacting a free trade agreement is D. Quotas and tariffs would increase.  option D is correct

What is in free trade agreement?

Two or more countries reach an agreement on a range of topics in a free trade agreement (FTA), including investor protections, intellectual property rights, and obligations affecting trade in goods and services.

A free-trade agreement  can as well be considered as the treaty,  however when we were considering  international law, this helps in creating a free-trade zone between cooperating states. The two types of trade agreements are bilateral and multilateral. Hence Quotas and tariffs would undoubtedly rise as a result of the implementation of a free trade agreement.

Therefore, option D is correct

Answer:

D. It was leased to the British until 1997, when it became part of China again.

Explanation:

    Hong Kong or officially the Hong Kong Special Administrative Region, is a special region of China that has existed since July 1997.

    China ceded the island of Hong Kong to the United Kingdom in 1842 after the First Opium War. Subsequently, the English annexed the neighboring Kowloon peninsula and the many smaller islands around the colony, which in treaty were leased for 99 years, which could be renewed for an equal period. The colonial apparatus will make Hong Kong an impressive development for the next 150 years or so as an outpost of the British Far East empire, becoming a major business and commercial hub.

Ring shaped islands called atolls _____.

B. are surrounded by lagoons

C. are a type of high island

D. are only found in Polynesia

(Gradpoint)

Answers

An atoll is when the island forms mostly around reefs, therefore creating lagoons. The correct answer would be A

Final answer:

Atolls, which are ring-shaped islands, encircle an inner lagoon. They are created over time as corals grow towards the surface as islands sink. Atolls are primarily seen in tropical and subtropical oceans but not only in Polynesia.

Explanation:

Ring shaped islands, commonly known as atolls, surround an inner lagoon. The formation of atolls is the result of corals growing in shallow waters around islands. As the islands sink over time, the corals continue to grow towards the surface, creating a lagoon within their ring-like structure. Despite being primarily found in the tropical and subtropical oceans, these atolls are not only restricted to Polynesia. So, the correct answer to this question is option A- surrounds an inner lagoon.
