The texture that results when extrusive igneous rock cools so quickly that crystallization doesn't occur is glassy. This texture is due to the rapid cooling process, which doesn't allow the formed minerals the time to crystallize.
Explanation:When extrusive igneous rock cools so rapidly that crystallization does not occur, the texture that results is glassy. This rapid cooling process denies the minerals within the lava the time to form crystals, thus resulting in an amorphous or glass-like structure. Examples of this type of rock include obsidian and pumice. On the other hand, Aphanitic texture is where the crystals are too small to see with the bare eye, usually because the rock cooled quickly. Phaneritic texture indicates that the rock cooled slowly, allowing the crystals to grow large enough to be seen without magnification. Porphyritic texture appears in rocks that cooled slowly at first, then more rapidly.

What economic resource does Switzerland lack?
minerals needed for heavy industry
land suitable for dairy farming
natural environment needed to attract tourists
skilled labor needed to produce precision goods
Final answer:
Switzerland lacks minerals needed for heavy industry and has instead specialized in high-precision industries like watches and medical equipment by investing in education and skilled labor. Each country's specialization, such as Vietnam's in rice and tourism, reflects their natural resources and economic strategies.
Explanation:
The economic resource that Switzerland lacks is minerals needed for heavy industry. Switzerland has limited natural mineral resources, which is why the country does not have a sizable heavy industry sector. Instead, Switzerland has focused on developing industries that do not rely heavily on natural resources but on other factors such as skilled labor, innovation, and high-quality education. To understand why Switzerland specializes in watches, precision instruments, and medical equipment, it is essential to recognize that the country has historically invested in educating its workforce and in the capital infrastructure necessary to support these high-precision industries. Similarly, factors like land and climate affect a country's production possibilities. New Zealand, for example, benefits from fertile soils and a mild climate conducive to agriculture and livestock, which are significant to its economy. These countries make strategic economic decisions based on their available natural resources and their ability to develop certain industries. In contrast, Vietnam's economic specializations such as rice cultivation and tourism are influenced by its natural environment, which is suitable for rice paddies and attracts tourists. The diversity in economic resources and specializations across different countries underlines the importance of trade to meet demands where there is an absence of natural resources.

The correct answer is - a collection of small kingdoms and city-states.
Italy, in the 15th century, was not a unified country, but instead, there were numerous small kingdoms and city states on its territory. These small kingdoms and city-states were varying in military and economic power, but in general, for small territories, they were respectably powerful.
All of these small kingdoms and city-states were ruled by local powerful families, whose main occupation was usually trade, apart from the Papal state, where the leader was the Pope of the Catholic church.
which of the following form part of the borders of almost all of the central american countries?
a. caribbean sea and mexico
b. caribbean sea and pacific ocean
c. North america and south america
d. pacific ocean and honduras
The answer is b. Caribbean Sea and Pacific Ocean, as almost all Central American countries are bordered by these two bodies of water to the east and west respectively.
Explanation:The correct answer to this question is b. Caribbean Sea and Pacific Ocean. Indeed, Central America is geographically positioned between the Caribbean Sea to its east and the Pacific Ocean to its west. This configuration results from Central America's land bridge formation, which extends from Mexico to the Isthmus of Panama, the narrowest point before South America. The region's physical environment also dictates that, except for Belize, the majority of Central American countries have coasts on both the Pacific and Atlantic Oceans (the Caribbean Sea being part of the Atlantic Ocean). Considering this, while other features such as the Gulf of Mexico and various countries like Honduras also occur in Central America, they do not border almost all of the Central American countries like the Caribbean Sea and Pacific Ocean do.

The best explanation for how humans populated the Earth is a. they migrated from Asia to other continents over the last two million years.
b. they migrated mostly over land from Africa over the last eighty thousand years.
c. they developed varied human species in different places over millions of years.
d. they traveled by boat from Africa to other continents over the last forty thousand years.
The best explanation for how humans populated the Earth is they migrated mostly over land from Africa over the last eighty thousand years. Option B is the correct answer.
Scientific evidence, such as fossil discoveries and genetic studies, supports the theory that humans originated in Africa and gradually spread out to other parts of the world. This process, known as human migration, occurred over a long period of time, with the majority of migration taking place over land. Option B is the correct answer.
The Out-of-Africa theory proposes that anatomically modern humans evolved in Africa around 200,000 years ago and then migrated to other continents. This theory is supported by fossil evidence, such as the discovery of early human remains in Africa, which are considered ancestral to humans found in other parts of the world. Genetic studies have provided further evidence for human migration out of Africa. By comparing the DNA of populations from different regions, scientists have identified genetic markers that indicate common ancestry with African populations. This suggests that populations in other parts of the world descended from early human migrants who left Africa.

Further detail:
The Industrial Revolution had its beginning in Great Britain, and eventually spread from there. Once the United States became involved, especially in the "Second Industrial Revolution" years (1870-1914), the size and resources of the country allowed the US to become a bigger industrial power than the nations of Europe.
Industrialization also led to the phenomenon of urbanization -- the movement of people away from the rural countryside and into cities. That led to other issues, like pollution and crime problems in cities. So sanitation and health measures were enacted, and the first police forces were formed.
The overcrowding conditions also meant poor living conditions in tenements and slums. The condition of these sorts of neighborhoods was documented by Jacob Riis, a police reporter in New York. In 1888, Riis took pictures of what life was like in New York City's slums. Using his own photos as well as photos gathered from other photographers, Riis began to give lectures titled, "The Other Half: How It Lives and Dies in New York," in which he would show the pictures on a projection screen and describe for viewers what the situations were like. He gave his lectures in New York City churches. In 1989, a magazine article by Riis (based on his lectures) was published in Scribner's Magazine. The book version was then published in 1890 as How the Other Half Lives: Studies among the Tenements of New York. Riis blamed the poor living conditions on greed and neglect from society's wealthier classes, and called on society to remedy the situation as a moral obligation.

Columbia River is a big river, and it flows through the northwestern part of the country. It is very important for the people that live in this part of the Untied States because the river flows into the Pacific Ocean, and it is big enough so that boats can move through it and go further in the mainland, so economically it is a very important feature in the region.

In which area does clean drinking water present the biggest problem? cities in LDCs polar regions tropical regions urban areas in MDCs
The correct answer is - cities in LDC's.
The cities in the LDC's (Least Developed Countries) are much different than the cities in the developed countries. They are not made with planning, the urbanization is on a very low level, the infrastructure is mostly lacking or is of very bad quality, and basic things for life of the people either are not there or only in limited amounts. One of the biggest problems is the drinking water because it is the essential thing that allows us to live, but in this type of cities it is very limited, on lots of places there isn't any, and very often it is not a water that is recommendable for drinking because it contains bacteria and pollutants.

how far was it along the silk road from Chang'an to dunhuang to marakanda to antioch ro rome
Answer:
It is estimated that it was approximately 8,700 km long.
The Silk Roads were an extensive network of trade routes from Chang'an to Rome, involving many different legs and frequent exchanges of goods among merchants. The precise distance would vary, but it was a journey of several thousand miles that few merchants completed in full, typically trading goods along the way.
Explanation:The Silk Roads were a vast network of trade routes connecting the East and the West, significant for their role in the exchange of goods, cultures, religions, and ideas. The journey from Chang'an to Dunhuang, onto Marakanda (Samarkand), Antioch, and finally to Rome would have covered thousands of miles, varying greatly depending on the specific pathways taken and the geographic and political landscape of the time. This network reached its peak between the fifth and eighth centuries, a time when the Tang dynasty in China and later the Islamic caliphate played prominent roles in its flourishing.
Setting out from Chang'an, the eastern terminus, merchants confronted the Gobi Desert and relied on caravansaries for rest and resupply. Localized trade was the norm, as goods changed hands frequently, increasing in price the further they traveled. When estimating the entire distance, it is essential to understand that it was rare for a single merchant to traverse the entire route. Instead, the trade goods would move through a series of exchanges from East to West.
Moreover, the Silk Roads facilitated not only trade but also cultural exchange, introducing religions such as Buddhism and Islam to new regions. The network began during the Han dynasty, thrived during the Tang dynasty, and saw changing control after the battle at the Talas River between the Tang and Abbasid empires. Through caravans and the perilous journeys of countless individuals, the Silk Roads shaped much of the ancient world's history.
