Answers

Answer:

Biomes with winter  between June to August  and summer  from December to March. are located in the southern Hemisphere

What is meant by Ideology?

An ideology is a set of views or philosophies attributed to a person or group of people, especially those maintained for reasons other than merely epistemic ones in which "practical aspects are as prominent as theoretical ones. In a tradition that dates back to Karl Marx and Friedrich Engels, the phrase was once used primarily to refer to economic, political, or religious theories and programs. More modern uses of the term are primarily critical.

In order to create a rational system of ideas to counter the irrational impulses of the crowd, the French Enlightenment nobleman and philosopher Antoine Destutt de Tracy, who is credited with coining the phrase, envisaged it as the "science of ideas" in 1796.

Scientists have established that some of the layers of Earth are solid, some are liquid, and some are semi-fluid. Explain how the scientists are able to determine the liquid and solid layers. Use at least two pieces of evidence to support your answer.

Answers

Answer:

Several studies has been made in order to understand the layers of the earth. Some of the evidences that proved the existence of solid and liquid layers are as follows-

1. According to the concept of Isostacy, the earth's crust is a like a solid  wooden block, that floats over a vast liquid which is compared here with the mantle. Due to the variation in the crustal density, the crust sinks or gets uplifted.

2. From the geophysical point of view, the study of the seismic waves made clear that the earth is comprised of three distinct layers such as the crust, mantle and the core. Crust refers to to top layer, mantle is the middle part and core is the interior part of the earth which is divided into two types, inner core (solid in nature) and outer core (liquid in nature).

Select the correct answer. What is the primary way that metamorphic rocks form? A. Lava erupts from Earth and cools. B. Water, wind, and gravity move particles from one place to another. C. Rock fragments break apart and collect as sediment. D. Existing rocks join together under high heat and pressure

Answers

Answer:

Existing rocks join together under high heat and pressure.

Explanation:

There are three major groups of rocks, igneous rocks, metamorphic rocks, and sedimentary rocks. Each of them has their own unique way in which they form. The igneous rocks are the basis for the formation of the other two, and they form from magma/lava that has cooled off. The metamorphic rocks form from preexisting rocks, where deep into the crust they experience high pressure and temperatures and change their properties. Sedimentary rocks form from the breaking apart from the previous two types of rocks, and later merging together under the right conditions.

The metamorphic rocks can have igneous, sedimentary, or mixed origin. In order for these rocks to form they need to be deep into the crust where the pressure and temperatures are much higher. The high pressure and temperatures lead to the merging of different types of rcoks, change their properties, and create a new type of rock. This is one of the reasons why the metamorphic rocks often have multiple colors and they are alligned like layers.

D. Existing rocks join together under high heat and pressure

B) Chinese is decreasingly popular in the United States.

C) immigration in the United States has slowed significantly

D) there is significant diversity in language usage in the United States.

Answers

Answer:

From this chart can be inferred that there is significant diversity in language usage in the United States.

Explanation:

The United States is the country with the biggest economy in the world, thus it is a country that has been the most attractive for migrants across the world for a long time now. While there are some ethnic and linguistic groups that dominate in the country, the fact that there are people from literally every country in the world living there means that the language diversity, at least at home is huge.

The English and Spanish languages dominate by far as those are the two languages that are native to most of the population, but when it comes to languages spoken at home the picture is much different. There are six languages that are officially spoken by one million or more people, including Chinese, French, German, Tagalog, Vietnamese, and Italian. On top of it, there are several other languages that have over half a million people using them, like Russian and Korean. If we take into account the languages that are spoken by less than half a million people then we will have hundreds of different languages on the spectrum.

B. They are located east of the Prime Meridian.
C. They are all part of the same empire.
D. They share a common religion.

Answers

Answer:

They share common climates and food sources.

Explanation:

The Mediterranean region is located around the Mediterranean Sea. There is an abundance of different people groups and multiple religions in this region. Despite this, the majority of the cultures tend to be very similar, with the people often having almost exact same habits and behavior.

The main reasons for this are the climate and food sources, both of which are shared by most of the people in this region. It is common knowledge that the climate and food sources have been big factors in the type of culture a particular group develops, and it is also very common that different people groups that share the same climate and food sources have very similar cultural traits. This is not something that is typical about the Mediterranean region but can be seen in many other regions such as Scandinavia, Central Asia, the Middle East, etc.

What was the first Southeast Asia countries claimed by European colonizers

Answers

Answer:

The first Southeast Asian country that was conquered and colonized was the Malacca Sultanate.  

Explanation:

Southeast Asia, as multiple other regions in the world, was colonized in most part by the European colonial powers. Pretty much all of this region was colonized, with only Siam (modern-day Thailand) managing to avoid colonization. The European countries that managed to colonize territories in this region were Portugal, Spain, Netherlands, Great Britain, and France.

The first European colony was created by Portugal. In the year 1511, the Portuguese attacked and conquered the Malacca Sultanate, thus making this country the first one to fall under European rule. This sultanate was located on the territories of what are now Malaysia, Singapore, and Indonesia. While this was the first European colony, it was short-lasting, as the Portuguese were not able to cope with the Spanish and Dutch forces which came after them.

Answer:

Portugal was the first European power to establish a bridgehead in maritime Southeast Asia with the conquest of the Sultanate of Malacca in 1511. The Netherlands and Spain followed and soon superseded Portugal as the main European powers in the region.

Overpopulation, religious persecution, lack of job opportunities, agricultural decline and conflict have been push factors for -
Educational Reforms
Migration
Determining Cultural Acquisition
Determining Life Expectancy

Answers

This question is asking about what is termed Push v. Pull. In the case of Push v. Pull, Push factors are typically (negative) events that force people away from their homelands into a different country, while pull factors (positive) are events that draw people to seek a better life in that country.

In this case, Migration is your best answer.

Overpopulation: With overpopulation, usually comes a lower standard of living, as the amount of funds provided by the state per citizen becomes drastically reduced per capita. This leads to those who are more fortunate to be "pushed" away from their homelands to a host country, in which standards are much higher and opportunities vary more greatly.

Lack of Job Opportunities: This essentially follows Overpopulation very closely. More people essentially means more people fighting for the same jobs, especially lower level jobs.

Religious Persecution: Religious Persecution is a big push factor, especially in areas of the middle east and the near east, in which religious persecution is rampant. People would typically try to move to a country that is more-dominant with their own beliefs, or a country that is more open to accepting their beliefs.

Agricultural Decline: Agriculture Decline typically means less food, which in turn means famine. Famine typically pushes many people away from the country in search of food elsewhere (neighboring countries), but recent efforts such as the World Food Bank and World Health Organization has been installed to counter such problems.

Conflict: Conflict is the single largest reason for people to migrate. Nobody wants to live in a warzone, and having an unstable environment impedes economic, social, and personal growth in every level. A steady and peaceful country that does not wage war (at least in it's own territory, as is the stand-alone United States of America), would always do better than a country rife with civil wars and foreign influences, which destroys economic growth, infrastructures, population, and the country as a whole.
