Which type of magma would you expect to produce the most explosive volcanic eruption?

A. low percentage of Silica (SiO2) with high gas content

B. low percentage of Silica (SiO2) with low gas content

C. high percentage of Silica (SiO2) with high gas content

D. high percentage of Silica (SiO2) with low gas content

Answers

Answer 1

Answer:

C

Explanation:

A high percentage of silica means that the viscosity of the magma is greater, this means it is more explosive.

Higher gas means more pressure on the magma so a more explosive eruption.

Answer 2

The high percentage of Silica with high gas content of magma would you expect to produce the most explosive volcanic eruption. Thus, option C is correct.

What is a volcanic eruption?

A volcano releases magma, which causes a volcanic explosion. Explosions can indeed be catastrophic or fairly quiet and expansive. Lava flows result from effervescent explosions, whereas ashes and ionized plasma are omitted in the environment.

As there will be a large amount of silica if present inside and also there will be a high gas content as well, as magma will be reacting with each other and creating a great amount of pressure.

The result will be a great amount of pressure that will intensify the eruption that will happen. Therefore, option C is the correct option.

Globalization of the world’s economy continues to have positive and negative consequences, depending on one’s perspective.
A. Define globalization.

B. Discuss in detail an example of one significant economic impact of globalization in a specific country, and examine how this impact may be viewed positively and negatively.

C. Discuss in detail an example of one cultural impact of globalization in a specific country, and examine how this impact may be viewed positively and negatively.

Answers

Answer:

A. the act or process of globalizing : the state of being globalized especially : the development of an increasingly integrated global economy marked especially by free trade, free flow of capital, and the tapping of cheaper foreign labor markets.

B. A example is Vietnam, where globalization has contributed to an increase in the prices for rice, lifting many poor rice farmers out of poverty. This is viewed a positive impact.

C. Cultural globalization has created unparalleled inequity throughout Africa, affected the behavior of people in numerous ways, and forced many people to assume a lifestyle of self interest, selfishness, individualism and made people to develop a psychopathic devotion and appetite for foreign films, foreign goods, foods, foreign way of life, foreign music, attitude and behavior. This is a viewed negatively.

Explanation:

Answer:

A. Globalization is the spread of technological advances, communication, and economic production from one culture to another.

B. A significant economic impact of globalization in Japan would be the collapse of their (previous) well-entrenched system of lifetime employment. Due to the lack of economic growth and failing markets, 1990s Japan was forced to reform the original Japanese labor model, and the integrating of American-style economic principles. Positively, this impact promoted the accumulation of capital, upgrades to the industrial structure, and technological advancements. Negatively, this impact affected the successful labor model that was followed before the globalization occurred.

C. An example of cultural impact of globalization in Germany would be that the country benefited greatly from higher flows of people and ideas. The people and ideas led to making slight changes in traditional religions and belief systems. They also began changing work ethics and rhythms that were to be followed. This impact may be viewed positively by having people work in better time frames and in safer environments. It may be viewed negatively by changing the traditions and belief systems some people were raised to believe for years. Sometimes people just do not want to see change in that aspect, they are so firm in their beliefs.

A quadrilateral has a perimeter of 207 units and one side measures 36 units. The lengths of the other three sides are in the ratio of 5:6:8. Find the lengths of the three missing sides.

Answers

Answer:

45, 54, 72

Explanation:

In this case, a quadrilateral is like a square, with 4 sides but it's sides are longer than a square.

The perimeter of any geometrical figure is the sum of all the side's lenght, so, if we have the perimeter and the value of one side, we can deduce the lenght of the other sides because we have a data of the ratio. Let's first see how much is left on the missing sides.

P = a + b + c + d

207 = 36 + b + c + d

171 = a + b + c

This means that the sum of the other 3 sides is 171. We know that the ratio of those sides is 5:6:8, so the sum of these sides can be written like this, in function of those ratios:

171 = 5x + 6x + 8x

171 = 19x

x = 9

With this number we can now calculate the sides of the quadrilateral:

a = 5x = 5 * 9 = 45

b = 6x = 6 * 9 = 54

c = 8x = 8 * 9 = 72

Therefore the missing sides's lenght are:

45, 54, 72

Read the two passages from "Everest Then and Now."Passage 1The earliest known survey of the mountain was in 1715. The Qing Empire in China studied the mountain while mapping its territory. In 1802, the British were conducting a survey of the highest mountains in the world. They wanted to measure Everest, but the government of Nepal did not allow them to enter the country. They suspected that the British might try to claim the mountain as their own. Five decades later, in 1852, an Indian mathematician and surveyor named Radhanath Sikdar identified Everest as the world's highest peak. The name Mount Everest was officially adopted as the English name for the mountain in 1865. It was named after Sir George Everest, an early British surveyor who was the head of the survey. What's interesting is that Everest objected to the mountain being named after him. He argued that his name was too difficult to pronounce in the local language, Hindi.Passage 2The increase in popularity means that more people are climbing Everest than ever. It's true that the economy of Nepal benefits from the hundreds of climbers each year. The government requires climbers to purchase a climbing permit. Climbers who hire Nepalese guides are also helping the local economy. However, more climbers on the mountain cause a number of problems. Large numbers of climbers on the mountain at once can be unsafe, especially when teams get close to the top of the mountain. This was not a concern in the early days of Everest explorers. Now, hiking companies encourage climbing teams to take turns when they get close to the peak. Climbers put in too much effort to get caught in a traffic jam near the summit.How is the structure of Passage 1 different from the structure of Passage 2? 1 Passage 1 uses a chronological structure, while Passage 2 uses a compare and contrast structure.2 Passage 1 uses a chronological structure, while Passage 2 uses a problem and solution structure.3 Passage 1 uses a compare and contrast structure, while Passage 2 uses a cause and effect structure.4 Passage 1 uses a compare and contrast structure, while Passage 2 uses a chronological structure.
