Latin America Geography
Glossary of Latin American Geography Terms
Altitudinal Zonation: The division of land into zones based on elevation, which affects climate, vegetation, and human activities.
Convective / Convectional Precipitation: Rainfall caused by the heating of the Earth's surface, leading to the rising and cooling of warm, moist air, which then condenses into precipitation.
Convergent, Divergent, Transform Plate Boundaries:
Convergent: Where two tectonic plates collide, often forming mountains or subduction zones.
Divergent: Where two plates move apart, leading to the formation of new crust, such as at mid-ocean ridges.
Transform: Where two plates slide past each other, causing earthquakes.
El Niño: A climate pattern characterized by the warming of sea surface temperatures in the Pacific Ocean, affecting global weather patterns.
Frontal Precipitation: Rainfall that occurs when warm and cold air masses meet, forcing the warm air to rise and cool, leading to precipitation.
Hadley Cell: A large-scale atmospheric circulation pattern in the tropics that influences climate and weather patterns.
Humboldt Current: A cold ocean current off the west coast of South America that affects regional climate and marine biodiversity.
Intertropical Convergence Zone (ITCZ): A region near the equator where trade winds converge, often resulting in heavy rainfall and thunderstorms.
Mediterranean Climate: A climate with hot, dry summers and mild, wet winters, found in regions like Chile and southern Europe.
Orographic Precipitation: Rainfall that occurs when moist air is lifted over a mountain range, cooling and condensing into precipitation.
Polar Front: The boundary between cold polar air and warm tropical air, influencing storm development.
Rain Shadow: A dry area on the leeward side of a mountain range due to descending, warming air.
Subduction Zone: A region where one tectonic plate is forced under another, leading to volcanic activity and earthquakes.
Subtropical High (STH): A belt of high pressure around 30 degrees latitude, leading to arid climates like deserts.
Chinampas: Floating agricultural islands used by the Aztecs to increase arable land.
Colonial Transfer of Wealth: The process by which European colonial powers extracted wealth from colonies through resource exploitation and trade.
Columbian Exchange: The transfer of plants, animals, culture, human populations, and diseases between the Americas and the Old World following European contact.
Criollo: A person of Spanish descent born in the Americas, often forming an elite class in colonial societies.
Demographic Collapse: A significant decline in population due to disease, war, or other factors, such as the impact of European diseases on indigenous populations.
Encomienda: A Spanish colonial system where settlers were granted control over indigenous labor in exchange for Christianizing them.
Haciendas: Large estates in Latin America that focused on agriculture and livestock, often worked by indigenous or enslaved labor.
Hearth Areas: Regions where early human civilizations and agriculture originated.
Latifundia: Large landholdings used for commercial agriculture, often owned by elites and worked by peasants or laborers.
Mestizo: A person of mixed European and indigenous ancestry in Latin America.
Milpa Cycle: A traditional Mesoamerican agricultural system involving crop rotation and fallow periods to maintain soil fertility.
Minifundia: Small-scale farms, often owned by poor rural farmers, producing food for subsistence rather than commercial sale.
Miscegenation: The mixing of different racial groups through marriage, cohabitation, or sexual relations.
Mulatto: A person of mixed African and European ancestry.
Peninsulares: Spanish-born individuals who migrated to the Americas and held high-ranking colonial positions.
Plantations: Large-scale agricultural estates growing cash crops such as sugar, tobacco, and cotton, often using enslaved labor.
Polyculture: An agricultural system where multiple crops are grown together, increasing biodiversity and soil fertility.
Pristine Myth: The misconception that the Americas were largely untouched by humans before European arrival, despite extensive indigenous environmental management.
Repartimiento: A Spanish colonial labor system that replaced the encomienda, requiring indigenous people to work for a set period under colonial authorities.
Swidden (Slash-and-Burn) Agriculture: A method of farming that involves clearing forests by burning vegetation, temporarily enriching the soil.
Terrace Farming: A technique of farming on steep slopes by creating flat terraces to prevent soil erosion and manage water use.
Triangular Trade: A three-part trade system between Europe, Africa, and the Americas, involving slaves, raw materials, and manufactured goods.
Administrative, Defensive, Extractive, Entrepôt Cities: Cities with specific roles in governance, military defense, resource extraction, or trade.
Favelas / Barrios / Informal Settlements: Unplanned urban settlements, often characterized by poverty and inadequate infrastructure.
Formal and Informal Sectors: The formal sector includes officially recognized businesses, while the informal sector comprises unregulated economic activities.
Inverse Concentric Zone Model: A model of urban structure in Latin America where wealthier populations live near the city center, unlike in North America.
Megacity: A city with a population exceeding 10 million people.
Overurbanization: A situation where urban population growth outpaces infrastructure and economic opportunities.
Self-Help Housing: Housing built by residents themselves, often in informal settlements.
Urban Primacy / Primate Cities: A city that is significantly larger and more economically dominant than any other in its country.
Urbanization: The process of population migration from rural to urban areas.
Bracero Program: A U.S.-Mexico agreement allowing temporary labor migration from Mexico to the United States.
Demographic Transition: The shift from high birth and death rates to low birth and death rates as a society industrializes.
Indigenous Peoples: The original inhabitants of a region, often marginalized due to colonialism and modernization.
Industrial Revolution: The period of rapid industrial growth in the 18th and 19th centuries, transforming economies and societies.
Machismo: A cultural concept emphasizing male dominance and traditional gender roles.
Medical Revolution: Advances in medical science that have increased life expectancy and reduced mortality rates.
Pardo: A term used in Latin America to describe people of mixed African, European, and indigenous ancestry.
Remittances: Money sent by migrants to their home countries, supporting families and local economies.
