Social Studies 7-12 10 Flashcards

The Mercator map projection, widely used in navigation and on many world maps, is most criticized by geographers because it:

Answer: Distorts the size of landmasses, making areas far from the equator appear far larger than they actually are

The Mercator projection preserves angles and compass bearings (making it useful for navigation) but severely distorts area. Greenland, for example, appears roughly the same size as Africa, when Africa is actually about 14 times larger. This size distortion increases the farther a region is from the equator.

David Ricardo's principle of comparative advantage in international trade argues that:

Answer: Countries benefit most by specializing in goods they can produce at the lowest opportunity cost, even if another nation produces those goods more efficiently in absolute terms

Comparative advantage holds that a country gains by specializing in whatever it produces at the lowest opportunity cost relative to trading partners—not necessarily what it produces best in absolute terms. This principle underpins the economic argument for free trade and international specialization.

The primary purpose of the Reconstruction era (1865–1877) in the United States was to:

Answer: Reintegrate the Southern states into the Union and establish civil and legal rights for formerly enslaved people

Reconstruction focused on restoring the rebellious Southern states to the Union and, critically, on defining the legal status of four million formerly enslaved people. Constitutional amendments (13th, 14th, 15th) abolished slavery, established birthright citizenship, and granted Black men voting rights during this period.

Which of the following best describes the U.S. system of federalism?

Answer: Governmental authority is constitutionally divided and shared between the national government and state governments

Federalism divides sovereignty between the national and state governments, with the Constitution granting certain powers exclusively to the federal government, reserving others to the states, and sharing some concurrently. This vertical division of power is a defining structural feature of American government.

The Cold War foreign policy doctrine of 'containment,' associated with diplomat George Kennan's 1946–1947 writings, was intended to:

Answer: Limit the further geographic expansion of Soviet communism without direct large-scale military conflict with the USSR

Kennan argued in his 'Long Telegram' and the anonymous 'X Article' that the USSR's expansionist tendencies could be checked through firm, patient counter-pressure at every point where Soviet influence sought to spread. This became the foundation of U.S. Cold War strategy from the Truman Doctrine through the end of the Soviet era.

In the social sciences, 'cultural diffusion' refers to:

Answer: The process by which cultural elements—such as ideas, technologies, and practices—spread from one society to another

Cultural diffusion describes how cultural traits cross group or geographic boundaries through trade, migration, conquest, media, or direct contact. It is a central concept in cultural geography and anthropology, explaining how innovations and practices that originate in one society eventually appear in others.
