Richter Scale (Escala de Richter): A seismic scale measuring earthquake magnitude based on the total quantity of energy released at the focus.
Mercalli Scale (Escala de Mercalli): A seismic scale measuring the intensity of an earthquake based on observed physical damage and structural effects.

External Geodynamics and Hydrology

Erosion (Erosión): The external geodynamic process that transports rock and soil materials from high-elevation zones down to lower elevations.
Delta: A coastal landform created by the accumulation and deposition of sediments at the mouth of a river.
Estuary (Estuario): A geographic coastal feature formed when seawater enters and penetrates the mouth of a river.
Atlantic Watershed (Vertiente Atlántica): The hydrographic watershed that concentrates the vast majority of the water resources within the Peruvian territory.

Climatology, Oceanography, and Meteorology

Humboldt Current (Corriente de Humboldt): The cold ocean current primarily explaining the extreme aridity across most of the Peruvian coast.
El Niño Phenomenon: A climatic and oceanographic phenomenon causing intense rainfall and storms along the northern coast of Peru.
La Niña Phenomenon: An atmospheric and oceanic phenomenon causing abnormal cooling of sea surface temperatures in the equatorial Pacific Ocean.

Manu National Park (Parque Nacional del Manu): A prominent Peruvian national park designated as both a UNESCO Natural World Heritage Site and a Biosphere Reserve.
Paracas National Reserve (Reserva Nacional de Paracas): A Peruvian protected natural area established to safeguard marine ecosystems and coastal biodiversity off the coast of Peru.

Demography and Population Dynamics

Natural Growth Rate (Crecimiento natural): A demographic indicator calculated by subtracting total deaths from total live births: $\text{Crecimiento natural} = \text{Nacimientos} - \text{Defunciones}$
Population Pyramid (Pirámide poblacional): A graphical bar chart representing the structural distribution of a population categorized by age groups and sex.
Population Aging (Envejecimiento poblacional): The demographic phenomenon characterized by a proportional growth in the elderly adult population relative to younger age groups.
Dependency Ratio (Índice de dependencia): A demographic indicator relating the size of the dependent population to the working-age population: $\text{Índice de dependencia} = \frac{\text{Población Dependiente}}{\text{Población en Edad de Trabajar}}$
Demographic Transition Model (Transición demográfica): A demographic theory explaining the structural shift from historically high birth and death rates to low birth and death rates as economic development occurs.

Fundamental Economic Concepts and Factors of Production

Scarcity (Escasez): The fundamental economic problem that arises because human needs and wants are unlimited while productive resources are strictly limited.
Opportunity Cost (Costo de oportunidad): The value of the next best alternative that is forgone or sacrificed when making an economic choice.
Complementary Goods (Bienes complementarios): Goods that are consumed jointly or in combination with one another.
Substitute Goods (Bienes sustitutos): Goods that can be used in place of one another to satisfy similar needs.
Enterprise / Firm (Empresa): The factor of production responsible for organizing, coordinating, and managing all other factors of production.
Remuneration to Capital: The economic return corresponding to the factor of production Capital is Interest (Interés).
Remuneration to Labor: The economic return corresponding to the factor of production Labor (Trabajo) is Wage / Salary (Salario).
Remuneration to Natural Resources: The economic return corresponding to Natural Resources (Recursos naturales / Tierra) is Rent (Renta).
Entrepreneurial Return: The income or return earned by the business owner or entrepreneur is Profit (Beneficio).

Stages of the Economic Process and Market Dynamics

Production (Producción): The stage of the economic process that creates and manufactures goods and services.
Distribution (Distribución): The stage of the economic process determining how generated income and wealth are divided among economic agents.
Circulation (Circulación): The stage of the economic process enabling the movement, commercial exchange, and trading of products.
Consumption (Consumo): The final stage of the economic process in which goods and services are utilized to fulfill human needs.
Law of Demand (Ceteris Paribus): When the price of a good increases, holding all other factors constant (ceteris paribus), the quantity demanded decreases.
Law of Supply (Ceteris Paribus): When the price of a good increases, holding all other factors constant (ceteris paribus), the quantity supplied increases.
Price Change in Substitutes: If the price of a substitute good increases, the demand for the related good increases.
Price Change in Complements: If the price of a complementary good increases, the demand for the related good decreases.
Decrease in Production Costs: When production costs drop, the market supply of the good increases.
Equilibrium Price (Precio de equilibrio): The price level established in a market where quantity supplied equals quantity demanded.

Market Structures and Price Disequilibria

Monopoly (Monopolio): A market structure characterized by a single vendor or seller supplying the entire market.
Oligopoly (Oligopolio): A market structure dominated by a small number of sellers or firms.
Monopolistic Competition (Competencia monopolística): A market structure characterized by numerous competing sellers offering differentiated products.
Market Shortage (Escasez): A condition that arises when the price is set below the equilibrium price, causing quantity demanded to exceed quantity supplied.
Market Surplus (Excedente): A condition that arises when the price is set above the equilibrium price, causing quantity supplied to exceed quantity demanded.
