How Do I Get A 5 On Ap Human Geography
There is no golden secret to getting a 5 on the AP® Human Geography exam. It takes a mixture of study habits, content knowledge, and practice to score high. A good portion of the exam is also interpreting data like graphs, charts and maps, so be sure to practice your skills with these aspects as well. However, there is also a wealth of resources to help you prepare for this exam at Albert.io:
Early History Of The Study Of Infrared Absorptions
One of the very useful properties of mid-IR spectra is that the region from 8500 nm to 12,500 nm is very characteristic for the molecule measured and this region is known as the finger-print region because it can be used to confirm the identity of many pure substances. While the study of mid-IR spectroscopy continued to grow, especially after World War II, interest in the NIR extended to quantitative measurements of water, a few simple organic compounds and a very few studies of specific proteins. No one considered it useful for characterising samples and it was considered too complex for use in quantitative analysis.
Demographic Transition Model Stage 2 Case Study: Afghanistan
In 2013, Afghanistan had one of the higher rates of natural increase in the world at 2.7% much higher than any other central Asian nation. Data provided from the Population Reference Bureau had the Afghan birth rate at and the death rate at . What is most significant here is that the death rate in Afghanistan is low and it continues to decline. Only a decade ago the death rate was over 20/1000, peaking around 2004. This fast reduction in the death rate is interesting to demographers because although life expectancy has risen quickly, one of the primary indicators of a lowered death rate remains high. Afghanistan currently has the highest rate of child mortality in the world, where one in ten children do not live passed the age of 5. Why then the decrease in death rate? Overall public health has greatly improved, and even though the child mortality rate is still high it is an improvement, as is the increased access to food and sanitation that has allowed adults to live longer. Quite remarkable for a country that has experienced so much war during the same time period.

An Introduction To Near Infrared Spectroscopy
A.M.C. DaviesNorwich Near Infrared Consultancy, 10 Aspen Way, Cringleford, Norwich NR4 6UA, UK
When you hold your hand out to a burning fire you feel the heat being emitted by the fire but what is happening? The fire gives out light and infrared radiation from a fire most of this is near infrared radiation. Some of the NIR radiation is absorbed by water molecules in your skin. This raises the temperature of the water and results in an increase in temperature in the surrounding tissue which is detected by nerves in your skin. This radiation was discovered in 1800 by William Herschel, a musician and very successful amateur astronomer because he wanted to know if any particular colour was associated with heat from sunlight. He found that the heat maximum was beyond the red end of the spectrum. Herschel could not believe that light and his radiant heat were related but he was wrong. By 1835 Ampere had demonstrated that the only difference between light and what he named infrared radiation was their wavelength. Then in 1864 James Maxwell wrote This velocity is so nearly that of light that it seems we have strong reason to conclude that light itself is an electromagnetic disturbance in the form of waves propagated through the electromagnetic field according to electromagnetic laws. What we now call the electromagnetic spectrum is shown in Figure 1.

What Is Nir In Ap Human Geography
4.8/5NIRNIRof the answer
In 2018, rate of natural increase for WORLD was 10.82 persons per thousand population. Rate of natural increase of WORLD fell gradually from 20.38 persons per thousand population in 1969 to 10.82 persons per thousand population in 2018.
Secondly, how is Nir computed? In demography, the rate of natural increase is a statistic calculated by subtracting the crude death rate from the crude birth rate of a given region. This rate gives demographers an idea of how a certain country’s population is growing. A country’s RNI can help determine which stage of the DTM they are in.
Subsequently, one may also ask, what is Ecumene in AP Human Geography?
The geographic term ecumene is used to describe land that is permanently populated by human society. It can also refer to industrial and agricultural land that is permanently used to sustain the human population.
What are the 2 big breaks in the demographic transition and what were their causes?
Identify the two big breaks and their causes. The first break: the sudden drop in the birth rate that comes from technological innovation. The second break: the sudden drop in the birth rate that comes from changing social customs. Low CBR and an increase in CDR thus a negative NIR.

Rate Of Natural Increase
30 | < -5 Data unavailable |
In Demography, the rate of natural increase , also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. It is typically expressed either as a number per 1,000 individuals in the population or as a percentage. RNI can be either positive or negative. It contrasts to total population change by ignoring net migration.
This RNI gives demographers an insight into how a region’s population is evolving, and these analyses can inform government attempts to shape RNI.
Distribution Of The Worlds Population
Economist Jeffrey Sachs, director of the Earth Institute at Columbia University, believes that there are two reasons why the global population and extreme poverty occur where they do:
- Capitalism distributes wealth to nations better than socialism or communism
- Geography is a significant factor in population distribution in relationship to wealth
For example, the population tends to be lower in extreme environments such as arid climates, rainforests, polar or mountainous regions. Another example is a nation that has a large body of water within its boundaries or has large mineral deposits or resources that are likely to have more wealth and a larger population.
Humans only occupy five percent of the Earths surface because oceans, deserts, rainforests, and glaciers cover much of the planet . The term for areas where humans permanently settle is ecumene. Population growth and technology dramatically increase the ecumene of humans, which affects the worlds ecosystems.
Additionally, regions that are too cold pose problems for large population clusters and food production. The cold Polar Regions have a short growing season, and many of the Polar Regions have limited amounts of moisture because they are covered by high- pressure systems . Thus, cold polar regions are defined by temperature and lack of moisture, despite access to snow, ice, and glaciers. Mountainous and highland regions lack population clusters due to steep slopes, snow and ice cover, and short growing seasons.

Why Are Ap Human Geography Scores Curved
Advanced Placement exams are designed to model college courses, many of which are curved. Also, one of the primary goals of the College Board is to maintain exam consistency over the years, even though the test questions change. So, the scoring guidelines are reflected to account for these needs. Make sure to note that since there is a curve, a 5 can be difficult to achieve. The curve is designed to give the majority of students a score of 3, which is why in 2016, only 12% of test takers received a 5.
Questions For The Future
Global human populations are often controversial because there is no clear consensus on dealing with it. Demographers know that there are over 7.3 billion people on the planet, but they are not evenly distributed worldwide. One consistent global pattern is water nearly 80 percent of the worlds population lives near a large body of water.
- Why do you think populations converge on large bodies of water?
- What happens to populations when there is a shortage of water?
There are various ways that geographers and demographers study population dynamics and profiles, often representing this data in diagrams, graphs, and, most importantly, maps. Social scientists have tried to describe historical, current, and future population trends with the Demographic Transition Model. The model attempts to explain how more developed countries progressed with their demographics than less developed countries today. Some argue that though the model predicts demographic trends in North America and Europe, the model does not accurately represent population trends in other regions of the world. Others say the model is too simplistic because of environmental and cultural factors.

What Region Is Experiencing The Fastest Population Growth
Three out of five of the most populous countries in the world are located in Asia. Ultimately the highest population growth rate is also found there, the country with the highest population growth rate is Lebanon. This could be due to a low infant mortality rate in Lebanon or the ever -expanding tourism sector.
Nir Technology For Routine Analysis Of Food And Agricultural Products
Near Infrared analysis is a spectroscopic technique that makes use of the naturally occurring electromagnetic spectrum.The NIR region is the area of the spectrum defined by wavelengths between 700nm and 2500nm. Near Infrared is an accurate and rapid analysis method that is well suited for quantitative determination of the major constituents in most types of food and agricultural products. The NIR advantageThe overall advantages of using NIR analysis is that it provides rapid analysis data for better decision making in food and agri production processes. Compared to traditional analysis methods it requires little or no sample preparation and no chemicals or consumables. It is non-destructive, operator friendly, fast , reliable and precise.How it worksThe working principle can be defined as follows:
- Near Infrared light is directed onto a sample
- The light is modified according to the composition of the sample and this modified light is detected
- The spectral modifications are converted to information regarding the composition of the sample
- These conversion algorithms are called calibrations
An infrared spectrum can be obtained by passing infrared light through a sample or the light can be reflected from the sample .

Which Climate Region Is The Largest In Canada
The largest zone by far is the Subarctic, which knows short, cool summers and long, cold winters, and low precipitation. All of southern Canada is classified as temperate that is, it has four seasons. Winter touches all zones, save the Pacific, where warm winds promote a mild, rainy climate year-round.
Key Factors Influencing Population Change
Three key factors to understand when trying to predict or analyze population change are the total fertility rate, infant mortality rate, and life expectancy at birth. Total fertility rate is the average number of children a woman would be expected to have during childbearing years . The global average for TFRs is about 2.5, but in less developed countries, it is as high as 5.0 or higher, and in more developed countries, it is as low as 2.0 or less. Fertility patterns can vary widely within countries. Racial and ethnic minorities may have higher fertility rates than the majority, and families with low incomes or low levels of education typically have more children than those that are affluent or well-educated. Women who work outside the home typically have fewer children than those who stay home, and rural families tend to have more children than city dwellers. In 2016, the number of births per 1,000 people worldwide was 20, with extremes ranging from a low of 8 or 9 , to 60 or more in a few West African nations .

Stage : Moderate Growth Rate
Today, Europe and North America have moved to Stage 3 of the demographic transition model. A nation moves from Stage 2 to Stage 3 when CBRs begin to drop while CDRs simultaneously remain low or even continue to fall. It should be noted that the natural rate of increase in nations within Stage 3 is moderate because CBRs are somewhat higher than CDRs. The United States, Canada, and countries in Europe entered this stage in the early 20th Century. Latin American nations entered this stage later in the century.
Advances in technology and medicine cause a decrease in IMR and overall CDR during Stage 2. Social and economic changes bring about a reduction in CBR during Stage 3. Nations that begin to acquire wealth tend to have fewer children as they move away from rural-based development structures toward urban-based structures because more children survive, and the need for large families for agricultural work decreases. Additionally, women gain more legal rights and chose to enter the workforce, own property, and have fewer children as nations move into Stage 3.
Stage : High Growth Rate
Around the mid-1700s, global populations began to grow ten times faster than in the past for two reasons: The industrial revolution and increased wealth. The Industrial Revolution brought with it a variety of technological improvements in agricultural production and food supply. Increased wealth in Europe and later North America because of the Industrial Revolution meant that more money and resources could be devoted to medicine, medical technology, water sanitation, and personal hygiene. Sewer systems installed in cities led to public health improvements. All of this dramatically caused CDRs to drop around the world. At first, CBRs stayed high as CDRs decreased this caused populations to increase in Europe and North America. Over time, this would change.
Africa, Asia, and Latin America moved into Stage 2 of the demographic transition model 200 years later for different reasons than their European and North American counterparts. The medicine created in Europe and North America was brought into these emerging nations, creating what is now called the medical revolution. This diffusion of medicine in this region caused death rates to drop quickly. While the medical revolution reduced death rates, it did not bring wealth and improved living conditions and development that the Industrial Revolution created. Global population growth is highest in the regions that are still in Stage 2.
