Understanding Iberian Peninsula’s Hydrology, Climate, and Soil
Factors of the Iberian Peninsula
Climate
Influenced by temperature and rainfall, Spain has two main climatic zones: wet (oceanic) Spain and dry (Mediterranean) Spain.
Relief
The relief influences watersheds, the erosive capacity of rivers and lakes, and aquifers. The terrain also affects the feasibility of hydraulic works. The type of rock determines water filtration capacity.
Vegetation
Vegetation curbs erosion, protects from solar radiation, and reduces evaporation.
Human Impact
Humans both utilize water

Cosmic Perspective and Evolution: From Big Bang to Modern Diseases
1. Cosmic Perspective and the Evolution of Life
1.1 Anthropocentric vs. Geocentric View
The anthropocentric perspective places humans at the center of the universe, while the geocentric system, like Ptolemy’s model, positions Earth at the center.
1.2 The Copernican Revolution
The Copernican Revolution shifted from a geocentric to a heliocentric system, with the sun at the center, resolving issues with Ptolemy’s model and explaining the movement of stars.
1.3 The Immensity of the Universe
Our sun is a

The Road to World War I
The Moroccan Crises
The First Moroccan Crisis (1905)
Triggered by Kaiser Wilhelm II’s visit to Tangier, the First Moroccan Crisis arose from Germany’s declaration of support for Moroccan independence. This move challenged the interests of France, Spain, Italy, and the United Kingdom, ultimately leading to the Algeciras Conference of 1906. The conference resulted in the division of Morocco, with Spain gaining control of the northern region and France controlling the central

Socio-Cultural Context
19th-century Spain witnessed a struggle between tradition and liberalism, culminating in the First Republic. The monarchy’s restoration led to political shifts between Liberals and Conservatives until the Second Republic in 1931. Primo de Rivera’s dictatorship (1923) preceded the unstable Second Republic and the Civil War, followed by Franco’s repressive regime.
Economically, Spain industrialized, with the textile and steel sectors gaining prominence. The population grew, and

Explanations of Life’s Origin and Diversity
Creationism and Fixity:
The creationist view holds that living things were created by a supernatural being. Fixity suggests that species remain unchanged over time.
However, these theories lack credibility due to fossil evidence showing changes in organisms over time, supporting the idea of evolution.
Aristotle held creationist ideas and classified animals:
- With red blood (vertebrates)
- Viviparous quadrupeds (mammals, except the oviparous platypus)
- Oviparous quadrupeds
Exploring the Settlements of Valleys and Plateaus in Patagonia
Valleys, Ravines, and Puna – WEST
7) Located at the oste settlements in the region, these areas have been part of large estates that emerged in the colonial period when Indigenous people held parcels. These settlements have been engaged in farming or raising livestock, and also as workers in the mining industry.
La Quebrada de Humahuaca is a valley formed by river erosion, part of the tour of the Rio Grande de Jujuy. Here, there are small oasis settlements and irrigation systems, such as Maimará
Understanding Weather and Climate: Elements, Factors, and Impacts
Weather vs. Climate
Often confused, weather and climate are distinct concepts. Weather refers to the atmospheric conditions at a specific time and place, determined by elements like temperature, pressure, wind, humidity, and cloud cover. It’s characterized by its rapid changes.
In contrast, climate represents the long-term average weather patterns of a region, typically over 30 years. While Madrid, Paris, and Caracas might experience similar rainy weather on a given day, their climates differ significantly,
