The bubbles are similar to a volcano that forms over a hot spot. how do volcanoes form island
Final answer:
Volcanic activity above mantle hot spots can lead to the creation of islands, such as the Hawaiian Islands chain. Heat from the Earth's mantle rises, and as tectonic plates move overhead, magma is pushed to the surface, creating volcanoes that can become massive mountains. Such islands form when this volcanic activity occurs under the oceanic crust, leading to effusive eruptions and the basalts that comprise the islands.
Explanation:
Volcanoes are fascinating geological formations that can lead to the creation of islands. One such way that islands are formed is through volcanic activity above mantle hot spots. A hot spot is an area deep within the Earth's mantle where heat rises towards the surface, independently of tectonic plate boundaries. The island of Hawaii, for instance, formed over such a hotspot that has been active for at least 100 million years. As the Pacific Plate moved over time, the stationary hotspot pushed magma to the surface, creating a chain of volcanic islands that includes Hawaii.
These volcanoes can become some of the largest individual mountains on Earth, with diameters over 100 kilometers and elevations rising about 9 kilometers above the ocean floor. Not all volcanoes are explosive; the ones in Hawaii typically erupt effusively, with lava flowing down their flanks, which can be less dangerous and allow for civilizations to thrive in close proximity.
Volcanic activity also includes subduction zones and collisions between continental plates, all of which contribute to the diversity of volcanic features on our planet. It's important to note that volcanoes created by hotspots can be particularly impressive since the lava is primarily basalt when it occurs under oceanic crust, leading to the distinct volcanic island features we see around Hawaii.
Where is quartzite most likely found
Quartzite, a non-foliated metamorphic rock formed from quartz sandstone, is most commonly found in tectonic zones where sandstones have been exposed to high amounts of pressure and heat, such as convergent plate boundaries and mountain-building regions.
Explanation:Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression. Quartzite is most likely found in areas where quartz sandstones have been subjected to high amounts of pressure and heat, specific tectonic zones such as convergent plate boundaries and orogens, or mountain-building regions.

In the mercator projection, which piece of the earth is portrayed ridiculously large in comparison to its actual size? in the mercator projection, which piece of the earth is portrayed ridiculously large in comparison to its actual size? the continent of africa brazil the continental u.s. greenland low-latitude locations
Final answer:
Greenland is the piece of Earth most drastically misrepresented on the Mercator projection map, depicted as nearly as large as Africa, which is actually fourteen times larger. High-latitude regions, such as Greenland and the continental United States, are shown much larger than their actual sizes.
Explanation:
In the Mercator projection, Greenland is portrayed ridiculously large in comparison to its actual size. The distortion of map sizes in the Mercator projection becomes significantly exaggerated as distances from the equator increase. For example, Greenland is shown nearly the same size as Africa on the Mercator map; however, Africa is, in reality, fourteen times larger.
Similarly, the continental United States also appears almost as wide as Africa when, in fact, it is far smaller. The United States, China, and India combined could fit within Africa with room to spare. As latitude increases, the Mercator projection exaggerates the size of countries and continents, leading to a skewed representation of true landmass sizes.

Why was it so hard to help the people of Burma following the devastating cyclone?
The reason why it was so hard to help the people of Burma following the devastating cyclone because the cyclone caused the worst natural disaster. This disaster highly affected the access to the people around there as that disaster damaged the roads and the buildings which became the reason of every kind of blockage. Cyclone Nargis made landfall in Myanmar, passing via the south of the country for about two days, and devastating the Ayeyarwady Delta region. The response of their government was not very good and was very slow. From the outside, we could see that the government had imparted so many limitations. Because of ill-management, and communication barrier because of destruction, the areas that needed immediate assistance could not be identified.

Correct answer: Turkey
Explanation/context:
When World War I erupted, the Ottoman Empire sided with Germany as part of the "Central Powers." In the end, the Central Powers lost and the Turkish empire of the Ottomans ceased to exist as an empire. Turkey remained as a country, but it lost control over other territories that it had held before.
The League of Nations created a system for governing former German and Ottoman territories, called "the mandate system." The mandate system authorized a member nation of the League of Nations to govern a former German or Turkish colonial area after the conclusion of World War I. There were mandate territories in Africa and Asia, as well as the Middle East. As an example, the former Turkish provinces of Syria, Iraq and Palestine in the Middle East were divided into a French mandate territory and British mandate territory. The British mandate rule over Palestine has much to do with the history of the development of the Arab-Israeli conflict.
What potential dangers do you see with creating polders that are below sea level

Even though the polders are made very carefully, everything is well planned, and all the required measures of long term safety of them are put in action, still there's always the concern of flooding hanging around. Because the polders are bellow the sea level, if by some chance the sea manages to penetrate in them, probably after some natural disaster, than the whole polder will be filled with water and become one huge pool, and because of this water everything in it will be destroyed in just a matter of minutes, thus lots of human lives will be lost, and a huge economic damage will be made.

what movement of people helped to bring a sense of unity of language to much of africa?
Bantu migrations helped bring unity of language to much of Africa.
Explanation:The Bantu tribe migrated from the south of West Africa to the Sub-Saharan countries excluding South Africa and Namibia. The tribe also dominated countries such as Kenya, Nigeria, etc. As they were spreading out to these countries, they introduced new skill and technology for crop-farming, harvesting and using the iron for making tools.
The Bantu migration to African countries introduced language which is evident today due to the similarity of languages in most of these countries. Up to 500 languages spoken in these regions, is attributed to the Pro-Bantu language.
Select the best hypothesis explaining why countries may have preferred communism.
Communism promised jobs after the insecurities of war.
Communists forced the people to do what they said.
Communism was fueled by a dislike for democracy.
Communism provided economic freedom for businesses and workers.
Final answer:
People were drawn to communism in the 1930s because it offered an alternative to the capitalist systems crumbling under the Great Depression, promising economic security and equality. However, the implementation often led to authoritarian regimes rather than the proletariat-driven society envisaged by communist theory.
Explanation:
Communism promised a radical form of economic and social organization where the state would control all property and means of production, theoretically allowing for equal distribution of resources and addressing the insecurities and inequities perceived in capitalist societies, particularly during times of economic hardship.
In the 1930s, the allure of communist ideology grew partly due to the economic depression that exposed severe inequalities within capitalist systems. Countries affected by high unemployment and poverty, especially post-World War I, saw communism as a beacon of hope as it offered a different pathway that promised economic security, full employment and the basic necessities of life such as food, healthcare, and housing.
In theory, communism aimed to establish an equal society by preventing the exploitation of workers, which was a stark contrast to capitalist societies where people lost jobs and homes during the Great Depression. However, in practice, the shift towards communist rule often resulted in authoritarian regimes which contradicted the ideology's promotion of a proletariat-led societal transformation, ultimately leading to numerous human rights violations.
Scientists worldwide agree that atmospheric carbon dioxide enhances the greenhouse effect. However, they differ in their opinions about the effects that the enhanced greenhouse effect has on the global climate. Which is the most likely effect of the differing opinions among scientists, regarding global warming?
A. All old ideas would be discarded.
B. Scientific evidence would be weakened.
C. New ideas would be created and tested.
D. The limitations of science would be evident.
Answer:
C. New ideas would be created and tested.
Explanation:
As global warming is happening in a large scale the scientist around the world are confused with whom to blame, but its not just the people that are responsible for this the given scientific evidence also provides of the fact that the life on earth is getting older and that earth along with its resources wealth is running out and going to get depleted fast as many countries have failed to understand the true potential of the nature they tend to blame there ideas. The scientific community does accept any sort of unstable hypothesis and hence focus on the new ideas and the try to test these out on a trial basis like the impact of the greenhouse and rise in the temperatures of places. Thus they are bound to differ in opinion and thus give new theories continuously.The most likely effect of the differing opinions among scientists, regarding global warming is new ideas would be created and tested. Option C is the correct answer.
The differing opinions among scientists regarding the effects of the enhanced greenhouse effect on the global climate would likely lead to the creation and testing of new ideas. This is because scientific research and understanding are built upon a process of questioning, experimentation, and evaluation. Option C is the correct answer.
When scientists have different opinions, it often leads to further exploration and investigation to gather more evidence and data. This can result in the development of new hypotheses, theories, and models that aim to explain and predict the impacts of the enhanced greenhouse effect on the global climate. Through this process, scientists can test these new ideas through experiments, observations, and analysis to gather empirical evidence and refine their understanding of the complex interactions between atmospheric carbon dioxide, the greenhouse effect, and global warming.

Describe how the meteorite collision at the end of the mesozoic affected the atmosphere and the biosphere
Dust and smoke were released into the atmosphere as a result of the meteorite crash. Plants were unable to undergo photosynthesis because the atmosphere allowed for considerably less sunlight to penetrate.
What do you mean by the meteorite collision?When a stony, metallic (usually iron), or frozen body that had been circling the Sun passes through the atmosphere and collides with the surface of the Earth, it is known as a meteorite impact.
A region known as the asteroid belt is where asteroids that orbit the sun between Mars and Jupiter's trajectories and produce many meteoroids collide. Asteroids collide and leave behind crumbly pieces of debris called meteoroids.
A significant amount of dust would be released into the atmosphere if the asteroid hit land.
Therefore, Dust and smoke were released into the atmosphere as a result of the meteorite crash. Plants were unable to undergo photosynthesis because the atmosphere allowed for considerably less sunlight to penetrate.

The Bantu migrations are most closely associated with the Colombian Exchange.
Question 12 options:
True
False
1) Pollution and acid due to industry and factories in urban areas. Africa has many problems, like famine, AIDS/HIV etc, but the pollution and acid due to industry and factories in urban areas are not a major issue right now. Though, as development does occur in some areas, this could become problems in the future.
---
2) A decrease in the usability of soil for agriculture. As deforestation progress, it is most likely that this issue would lead to a decrease in the usability of soil for agriculture, just like it is already happening in Amazonia and others regions that have faced similar problems.
---
3) Most Egyptian people lived and still live today close to the Nile river and Nile Delta because it is close to land that can grow crops. The majority of the Egypt agricultural production is located near the water of the Nile, the longest river on the Earth, as it permits the cultivation of various forms of crops.
---
4) If population growth occurs in an area that depends on farming, a direct result could be that deforestation will occur to clear land for additional farms. This happens because, as there is a grown in population, there is a growing in the demands of products derived from farming, and so more farms are needed in order to supply the demand. Deforestation occurs to make space for new farms.
---
5) The best term that could be used to describe the process of putting more trees in this area is reforestation. Reforestation is the opposite of deforestation, and as deforestation is a process in which trees are cut from the forest, reforestation is a process that puts more trees in an area.
---
6) People in South Africa would be most affected by the spread of the Kalahari Desert. The Kalahari Desert, situated mainly in Botswana, is spreading into other regions, including South Africa. Desertification is a process that could affect many sectors of the economy in the region.
7) People in Sub-Saharan Africa are least likely to live in a desert. Sub-Saharan Africa is the area of the continent that is situated fully or in part under the Sahara Desert, according to the United Nation. It is an area in which poverty is extremely diffused and that is still facing many issues.
---
8) True. The majority of Sub-Saharan African cities are located along major rivers, and the coast, because they needed access to bodies of water for trade. Historically, this was the normality for many cultures, as the access to water guarantee an access to trade and sometimes food, so it should come as no surprise that major city in the area still follows this principle.
---
9) The factor is most likely to have had the greatest impact on human settlement patterns in Sub-Saharan Africa is the proximity to water sources needed for subsistence farming. This is because water is a basic need in order to farming, so the impact would be likely to be more extended in those regions.
---
10) People in the Democratic Republic of Congo would be most affected by rain-forest conditions, as it happens that the Democratic Republic of Congo is situated where there is one of the biggest rainforests still present on the planet, so this is a factor that is a big influence on the people living in the region.
---
11) The relationship between literacy rates and a nation's standard of living is that a higher literacy rate will have a positive effect on a nation's standard of living. This happens because a higher literacy rate means more people with an higher education which mean more capable of creating or bring new jobs, which led to higher nation’s standard of living.
---
12) False. The Bantu migrations are NOT most closely associated with the Colombian Exchange. The Bantu migration happened between 1000 A.D. to 1800 A.D., while the Colombian Exchange happened during the XV and XVI century, but the two migrations are not related.

why are areas along the west coast of California cooler then you would expect for their latitude
a cold ocean current travels along the coast
these areas are far from a large body of water
these areas are at higher altitudes
a warm ocean current travels along the coast
Areas along the west coast of California cooler then you would expect for their latitude because a cold ocean current travels along the coast.
Answer: Option A
Explanation:
The west coat of California gets a cold current that is carried from the polar regions to this region. The cold currents make the air cooler and lower the temperature. This is why west coast of California is cooler when compared with the latitude and also colder than the east coast.
On the eastern coast, a warm current keeps the temperature warmer. The cold current brings very cold air because it flows from the polar regions and therefore keep the temperature low.
