Raw Materials and the Secondary Sector: Energy and Industry
Raw Materials and the Secondary Sector
The secondary sector encompasses activities necessary for transforming raw materials into consumer products. The primary activity of this sector is industry, but it also includes energy production and construction.
Raw Materials for Industry
Raw materials are essential for industry and are of various types:
- Animal
- Vegetable
- Mineral:
- Metallic minerals (e.g., bauxite, iron, lead)
- Non-metallic minerals (e.g., sulfur, salt)
- Clay
- Mineral carbon energy sources (e.g., oil,
Hominization and Colonization of the Iberian Peninsula
Process of Hominization
The first representatives of the genus Homo from Africa arrived in Europe at the beginning of the Pleistocene, which began 1.5 million years ago and was characterized by a succession of four glaciations. Our ancestors, affected by these glaciations, sought refuge in more southern areas, among them the Iberian Peninsula. This explains why the oldest hominid fossil remains found in Europe (dating from 800,000 BC) are located in Spain, in the Sierra de Atapuerca. These remains,

Confiscation in Spain: A Long Historical Process
The Confiscation, also known as Disentailment, was a long historical and economic process in Spain. It began in the late 18th century under Godoy (1798) and concluded in the 20th century (December 16, 1924). Other countries experienced similar phenomena. It consisted of putting on the market, through public auction, land and unproductive assets held by the so-called “dead hands” — almost always the Catholic Church or religious orders, and territories

Climate
What do temperature, wind, and rain have in common? They are all part of the climate!
The whole surface of Earth is a series of the same climates… so they are grouped in biomes.
Biomes
Biomes are geographical areas that share a similar climate, fauna, and flora.

The Industrial Revolution: Origins, Phases, and Impact
I: The Industrial Revolution – Beginning in the 18th century, the Industrial Revolution brought about the development of industrial and factory complexes, new forms of communication, and large human settlements.
I.1: The core of the revolution was the development of large-scale production based on energy sources other than human or animal power. Machines, concentrated in factories, became central to production.
I.2: Phases of the Industrial Revolution:
