Unit 1 Review Land, Resources And People A primary source is a source of information taken from an original document, text or audio video. Most of the Earth’s surface is covered by water Mountains, plateaus and plains are examples of landforms. Due to an increase in food supply and better medical care, the world’ population recently, has increased, rapidly. To the right is the Western Hemisphere. Latin America is shaded in green. Above is a view of the Western Hemisphere. It is made of North and South America. Canada United States To the left is a view of Latin America. It is made of South America, the Caribbean Islands and Middle America, which is Mexico and the 7 countries of Central America. Weather is the condition of the air and sky from day to day. Canada Since Canada is a long way from the Equator, the climate tends to be very cold. Equator Equator Latin America’s climate is affected by elevation, the Equator and wind patterns. Life in the mountains are cooler. Hotter weather is found near the equator. Strong winds blow warm air away from the Equator and colder air is blown up from the south, the Antarctica. ELEVATION… is the height of land above sea level A plateau is a large, mostly flat area that rises above the surrounding land. Much of Mexico is a plateau. The Amazon River Basin is home to the largest tropical rain forest in the world. Amazon Rain Forest Due to an excellent supply of heat, light and water, thousands of different kinds of plants grow in the rain forest. The Andes Mountains is the long mountain chain that runs along the west coast of South America. Crops grown on farms in the Andes are influenced by elevation. Subsistence farms raise enough food to feed only the farmer’s family. The economy is a system of producing, distributing, consuming and owning goods, services and wealth. When a country depends largely on one resource or crop for income, it is known as a one-resource economy. To reduce their reliance on one natural resource or crop, many Latin American nations have begun to build up their industries. The drop in oil prices in the 1980s probably helped to convince Venezuela to promote investment in other industries, (diversify). Fossil fuels are resources that were created over millions of years from the remains of prehistoric plants and animals. Coal and natural gas are examples of nonrenewable resources. Migration is the movement of people from one country or region to another. Push-Pull Theory is used by Involuntary migration is geographers and demographers when people are forced to move from one to explain migration. When people location to another. living in a region find it difficult to live, they feel a push to move away in search of better paying jobs or better schools and medical care. The hope for better living conditions pulls them to a new location. Many people have moved (migrated) from the rural areas shown below right, to urban areas for better paying jobs and to give their children better opportunities, in the areas of health and education. Many people in Latin America leave the rural countryside for the urban, city life, in hopes of finding better jobs. Urban refers to the city.
