Morphostructural Units of the Iberian Peninsula

Galician Massif

The Galician Massif underwent Tertiary rejuvenation during the Alpine orogeny. It forms the western part of the northern Meseta plateau and is made up of Paleozoic materials. Its relief consists of rounded mountains cut by numerous fault systems.

Cantabrian Cordillera

The Cantabrian Cordillera was formed during the Tertiary as a consequence of the Alpine orogeny. In the western sector of the cordillera, the Asturian Massif is made up of Paleozoic materials and forms a relief of high peaks and abrupt slopes. In the eastern sector, the materials are Secondary and Tertiary sediments deposited in a sea that covered the northern edge of the plateau. The Alpine orogeny lifted these materials...

Key Urban Terms

Urban area — a built-up area such as a town or city.
Urbanisation — an increasing proportion of people living in urban areas.
Urban growth — an increase in the number of people living in a city.
Migration — the movement of people from one place to another.
Natural increase — when birth rates are higher than death rates.
Megacity — a city with a population of more than 10 million.
World city — a city with major global influence over finance, business, politics and culture.

Patterns of Urban Movement

Suburbanisation

Definition: People move from the inner city to the suburbs.
Causes: More space, gardens, quieter surroundings and better access to family housing.
Consequences: Suburbs expand, commuting increases and inner-city...

Essential Equipment for River Load Analysis

You will need the following equipment for river load investigations:

• Cord or washing line: To stretch across the river to act as the base-line for your investigations.
• Tent pegs: To secure the base-line.
• Metre rule: For measuring depth and distance.
• Scoop: A dustpan may also be useful.
• Scale of roundness: This will help you to pick out particular shapes in the materials you investigate. Five main shapes are recognized, and you can make a set from pencil erasers. Some patience will be needed! Label each eraser with indelible (waterproof) ink. Your reconnaissance visit will have shown whether you need all five shapes or just 'angular', 'sub-rounded', and 'well-rounded'.
• Quadrat: For choosing river-bed material,

Physical Factors Affecting Agriculture

The physical environment plays a crucial role in agricultural viability. The primary physical factors include:

• Terrain and Relief: Mountains present challenges due to altitude, temperature variations, and rainfall. Slope orientation is critical: sun-oriented slopes are warmer, while windward slopes (oriented to prevailing winds) are wetter than leeward slopes. Steep slopes can cause soil erosion and hinder mechanization. Conversely, fertile plains and valley bottoms provide the most favorable relief for agricultural activities.
• Climate: Climate influences plant development through insolation, temperature, precipitation, and wind. Extreme sunshine, temperature, and rainfall can make agriculture impossible.

Types of River Regimes

River regimes describe the characteristic annual variation in a river's flow. Several distinct types are recognized:

Nival Regime

This regime, known as the Nival Regime, is typical of higher mountain areas where waters freeze in winter, leading to a period of low flow. From early spring to late summer, the river receives a significant contribution from meltwater, resulting in increased flow.

Nivopluvial and Pluvionival Regimes

In these regimes, both nival (snowmelt) and pluvial (rainfall) factors combine. The nival factor is typically felt earlier than in purely nival regimes. These rivers are also influenced by rainfall during wetter months. Such fluvial regimes, often referred to as Nivopluvial and Pluvionival Regimes, occur...

The Primary Sector: Core Activities

The primary sector comprises activities focused on obtaining food and raw materials directly from nature. This includes:

• Agriculture: Cultivation of crops.
• Livestock: Rearing of animals.
• Fishing: Harvesting aquatic life.
• Forestry: Management of forests for timber and other products. This sector currently accounts for approximately 39% of forestry activities.

Farming Activities and Influencing Factors

Farming activities hold a very important place for the population and are conditioned by several key factors:

• Weather

  Each crop requires specific climatic conditions, including temperature and humidity, for optimal development.

• Relief

  Agriculture is typically easier in wide plains. Slopes make work more difficult and often

Colombia's International Land Borders

Venezuela Border

The border with Venezuela was defined by the Maria Cristina-Rina España Treaty of March 1891 and the Lopez de Mesa-Gil Borges Treaty of April 5, 1941. It spans 2,219 km, stretching from Castilletes in La Guajira to the San Jose de Cocuy Island on the Negro River.

Brazil Border

The border with Brazil is established by the Vasquez-Cobo-Martins Treaty (April 24, 1907) and the Ortiz-Garcia-Mangabeira Treaty (November 15, 1928). It covers 1,645 km, from San Jose Island to the mouth of the San Antonio Creek on the Amazon River.
