Explanation:
Human systems, one of the six essential element of geography, can best be described as the study of where people live and what cultures they create.
Geography comes from the Greek "geo", which means earth, and "graphy" which means drawing. At the beginning geography was only the study of maps, but in time geography becomes the study of 6 essential elements:
Human System is the study of people in a certain environment that surrounds them. It observes how cultures and behaviors are defined by the location in which they live.
The world in spacial terms is referred to the study of maps and everything that is connected to the spacial contest.
Places and regions is about how people create culture in particular places called regions.
Physical system is about study of earth in a physical way like volcanoes and oceans.
Environment and society study how we interact with nature and we adapt the natural system to fit our needs.
And last but not least the use of geography teaches people how to connect all these elements into a coherent frame to study the earth and humans.
Answer:
b)-2.4% year
Explanation:
The population growth can be calculated by the following equation.
In which is the population in t years from now, is the population in the current year and r(decimal) is the growth rate. is the Euler number.
The current population of South Korea is 50 million, so
2750 is 2750 - 2019 is 731 years from now. So we have that . The population is going to be extinct, so .
So, we can replace the values of and t in the equation, and see for which growth rate .
a) 0.012 % year
This is a positive growth rate, which means that the population will not be going extinct. So this is not the alternative
b)-2.4% year
Population of 1 person, basically extinct. This is the correct answer
c)-0.01% year'
Population still at 24 million, it does not goes extinct.
d)-0.012% year
Population still at almost 21 million, it does not goes extinct.
The water flowing in a stream or river is fed by numerous smaller streams, which are fed by even smaller streams that collect water from melting snow or ice up in the mountains, from springs, and possibly from human wasterwater sources. The bottoms of rivers are also below the water table in many places, so there will always be water at that level.
