Asturian Architecture: Royal Influence & Pre-Romanesque Style
Asturian Architecture
The architecture was driven by the Kings.
Characteristics
- Prevalence of the basilica form.
- Curvilinear and volumetric designs.
- Emphasis on line, masonry, and blocks.
- Tall buildings with arched vaults, transverse arches, or ribs (prelude to Romanesque).
- Arches resting on attached columns, linked by arcs (Romanesque influence).
- External buttresses.
- Horseshoe arches, sometimes decorative or supportive.
- Fluted columns, Corinthian capitals (vertical or helical), tapered and double inverted.
Non-Conventional Energy Sources: A Deep Dive
Non-Conventional Energy Sources
Solar (heliothermal, photovoltaic), wind, geothermal, tidal, other sources (wave, ocean thermal), and biomass (including MSW) are key non-conventional energy sources.
Solar Energy
Solar energy can be utilized in two ways: heat (absorbing energy and transforming it into heat) and photovoltaic conversion (directly converting solar energy into electrical energy).
Heat from Solar Energy
A collector absorbs solar radiation and transfers it to a fluid, significantly increasing

Earth’s Dynamic Equilibrium
Heating and Density
The sun heats the Earth’s surface, warming the surrounding air. The core heats the planet’s interior. This uneven heating creates density differences, causing less dense materials to rise.
Water Cycle
The water cycle, powered by solar energy, distributes heat throughout the world’s oceans. This oceanic current cycle is sometimes called the “oceanic conveyor belt.”
Mantle Movements and Volcanoes
Mantle movements cause the ascent of deep materials, fueling

Acid Rain
Formation and Causes
Acid rain results from emissions of nitrogen oxides and sulfur oxides from factories, power plants, metallurgical industries, and vehicles burning fossil fuels like coal and petroleum.
Mechanism
Water from clouds reacts with these oxides to form sulfuric and nitric acid, resulting in acid rain with a pH of 3-5.
Border Phenomenon
Primary atmospheric contaminants can travel long distances, carried by winds for hundreds or thousands of miles before being deposited through mist,

Natural Resources and Industry in Spain
Industrialization in Spain is influenced by natural and human factors, including economic, technical, and political considerations. Raw materials, essential for industrial use, are categorized as mineral (metallic and non-metallic) and organic (plant and animal).
Raw Materials
Mineral Raw Materials
Mineral raw materials are non-renewable but reusable.
Metallic Minerals
- Iron: Abundant throughout Spain, though often of poor quality. The traditional mining area in
Key Environmental Terms and Definitions
Environment
Environment: A complex system of abiotic elements (solar energy, soil, water, and air) and biotic elements (living organisms) that form the Earth’s biosphere, supporting life.
Pollution and Contamination
Pollution: The presence of substances, elements, or energy in the environment at concentrations exceeding legal limits, posing a risk to health and ecosystems.
Contaminant: Any element, compound, substance, or energy whose presence in the environment, at certain levels or durations, may
