The Tertiary Sector

The tertiary sector encompasses activities that do not produce material goods but provide services to individuals, companies, and the government. This sector is a key indicator of a country's economic development and employs a significant portion of the workforce in developed nations.

Importance of the Tertiary Sector

The tertiary sector plays a crucial role in modern economies. In developed countries, it provides jobs for approximately 60% of the active population. For instance, in Spain, it accounts for 76% of employment and over 72% of GDP. A thriving tertiary sector is a hallmark of a developed economy, often accompanied by a welfare state.

Classification of Services

Services within the tertiary sector can be categorized...

Castile and Aragon: A Dynastic Union

The Modern Age began in Spain with the reign of the Catholic Monarchs, Isabella I of Castile and Ferdinand II of Aragon. Their marriage in 1469 marked the first step towards the union of the Kingdom of Castile and the states under the Crown of Aragon, effectively uniting them in 1479. This union, however, was primarily dynastic, meaning the territories shared monarchs but retained their own institutions, laws, and monetary systems. Despite this, the union established common goals, including religious and territorial unity and increased monarchical power.

Religious and Territorial Unity

The first step towards territorial unity was the incorporation of the Nasrid kingdom of Granada in 1492, concluding the peninsular...

Consequences of Colonization in Africa

In just 20 years, starting from the 1884 Berlin Conference, Africa was completely colonized. Due to the continent's perceived impenetrability, colonies were demarcated along artificial meridian lines and parallels. This arbitrary division often grouped disparate ethnic, religious, and cultural populations within single states, leading to significant consequences. While pre-colonial Africa was characterized by tribal affiliations rather than unified nations, resulting in frequent inter-tribal conflicts, colonial boundaries exacerbated these tensions. Furthermore, colonial powers established systems of economic exploitation, prioritizing resource extraction over infrastructure development for local populations....

The Emergence of Medieval Cities and the Bourgeoisie

By the eleventh century, the terror of barbarian invasions had largely disappeared. After centuries of a subsistence rural economy, improved agricultural practices began to produce a significant surplus. As is often the case with agricultural surpluses, two key activities developed: trade and specialization (also known as the division of labor). This latter characteristic is fundamental to the settlements we now call cities.

Unlike ancient cities, which were often organized around individuals possessing essential knowledge for survival, medieval urban centers saw merchants and craftsmen gravitate towards the castles of lords, abbeys, and other wealthy strongholds that had accumulated riches...

Agricultural Land Classification

Agricultural land (parcelas) is classified based on:

• Size
  • Small: Less than 1 hectare
  • Medium: 1 to 10 hectares
  • Large: More than 10 hectares
• Shape
  • Regular: Geometric shape
  • Irregular: Not a defined geometric shape
• Boundaries
  • Enclosed fields: Separated by hedges, fences, or stone walls
  • Open fields: No physical boundaries

Corrective Measures

Agriculture and Livestock

• Use of manure and fallow techniques
• Use of organic products for pest control
• Use of natural seeds and seasonal planting
• Rational use of water resources

Forestry

• Conservation of natural areas with high ecological value
• Reforestation with native species
• Fire protection

Fisheries

• Regulation of fishing gear and techniques (e.g., trawling ban)
• Minimum size control for species
• Reduced

The Importance of the Service Sector

The service sector plays a crucial role in modern economies, exhibiting distinct characteristics in developed and underdeveloped countries:

• Diversity: In developed countries, services are widespread and diverse, while in underdeveloped countries, more basic services predominate.
• Access: The majority of the population in developed countries has access to a wide range of services. In contrast, access to services is limited for a significant portion of the population in underdeveloped countries.
• Contribution to GDP: In developed countries, a significant portion of GDP comes from business and public services. In underdeveloped countries, personal services contribute more significantly.
• Employment: Developed countries

Terrestrial and Aquatic Ecosystems

On Earth, there are terrestrial and aquatic ecosystems. Both share the following characteristics:

• Solar energy is essential for the development of life.
• They have the same trophic levels: producers, consumers, and decomposers.
• Matter and energy flow continuously.
• Living creatures adapt to their environment.

Differences Between Terrestrial and Aquatic Ecosystems

• In aquatic environments, nutrients and gases are dissolved in water.
• Temperature changes are minimal in aquatic environments.
• Light is a limiting factor for production in aquatic environments because there is little light below 100 meters in depth.
• Pressure has a greater effect in aquatic environments.

Ej 11: Industrial Revolution

• Around 1830
• Two main characteristics: slow and partial
• Five causes of industrialization: low demand for industrial articles, lack of entrepreneurial spirit among the bourgeoisie, technological gap, shortage of raw materials, political instability
• Basic industrial sectors: mining, iron and steel industry, textile sector
• Concentrated in Catalonia: textile sector
• Transport: thanks to the law of highways
• First railways: Barcelona-Mataro, Madrid-Aranjuez
• Scarce due to reduced international demand
• Badly affected by the loss of American

Treaty of Tordesillas

In 1493, the Pope divided all newly discovered lands outside Europe between Spain and Portugal along a line in the Atlantic Ocean. However, the Spanish and Portuguese disagreed about the position of the line. In 1494, they met at Tordesillas, where they agreed on the line of longitude 370 leagues west of the Cape Verde Islands. This agreement was called the Treaty of Tordesillas. However, most other European countries ignored the treaty.
