Answer:
major cities
bodies of water
international borders
Explanation:
The political maps are type of specialized maps that are showing the reader of the map the countries, be it in the whole world, in a region, or in a smaller area.
These maps are always showing the international borders between the countries, which is actually its main purpose, differentiation of the countries and representation of their borders.
Very often, the major cities tend to be represented as well, and it can only be the capital cities, or cities that are very large and important.
The major bodies of water too tend to be represented, as the borders between the countries often go through a water body, or the water bodies are surrounding a country.
Every country is usually depicted with different color, so that the reader of the map is able to differentiate the countries much more easily.
An example would be "A very large ice formation that has broken of of Antartica."
In order for an economist to compare the living standard in two different countries, he/she will need to take multiple parameters in consideration and compare all of them individually, after them sum them up and make the final conclusion.
One of the things is the GDP nominal of the countries, which shows how strong the economy of the country is, and in which direction it is moving. Then the GDP per capita, which will reflect how much actually the citizens earn on average. The prices of the goods and services in the countries come as next, and their prices are then compared with how much the GDP per capita, so that the economist can see what is the economic power of the citizens. The availability and quality of the institutions of the countries, the infrastructure, corruption rate, freedom of speech, will all be examined in order to determine the living conditions that are available to the people. So once all of these things are examined and summed up, the economist will be able to make a proper comparison of the standard of living in the two countries.
Based on cartographic material from three time periods during the nineteenth and twentieth centuries, the impact of river capture, which started in the middle of the nineteenth century, on transformations of the watershed and hydrographic network of two Lithuanian rivers, Ula and Katra, is analysed. It has been determined that river capture conditioned marked transformations of water supply and distribution. As a result of the capture, the area of Ula catchment has increased by 62% and its mean discharge by 63%, whereas the area of Katra catchment decreased by 23% and its mean discharge by 27%. The total area of the five largest lakes in the recent Ula catchment has been reduced by 95%. The transformations of water resources in the Ula catchment since the first half of the nineteenth century are the following: Ula runoff volume has increased almost by 100 million m3/yr whereas the water volume of lakes has been reduced by almost 30 million m3.
river ecosystems support a disproportionately large fraction of its biodiversity, while acting also as significant corridors for the movement of plants, animals and nutrients
