Earth’s Human and Cultural Geography Movement The human population is growing rapidly, but the world in which people live is, in many ways, becoming a smaller place. In the past, many cultures were isolated from each other. Today , individuals and countries are linked in a global economy and by forms of communication that can instantly bring them together. What factors bring about changes in cultures? 70 • Chapter 3 ML Sinibaldi/CORBIS Section 1: World Population BIG IDEA Geographers study how people and physical features are distributed on Earth’s surface. Although the world’s population is increasing, people still live on only a small part of the Earth’s surface. Section 2: Global Cultures BIG IDEA Culture influences people’s perceptions about places and regions. The world’s population is made up of different cultures, each of which is based on common beliefs, customs, and traits. Section 3: Resources, Technology, and World Trade Canal market, Thailand BIG IDEA Patterns of economic activities result in global interdependence. Because resources are unevenly distributed, the nations of the world must trade with each other. New technologies make the economies of nations more dependent on one another.

Population density represents an average. Remember that people are not distributed evenly throughout a country. Argentina, for example, has a population density of 36 people per square mile (14 per sq. km). However, the density around the city of Buenos Aires, where nearly one third of Argentina’s people live, can be as high as 5,723 people per square mile (14,827 per sq. km).
