Earth’s Structure and Plate Tectonics: A Comprehensive Study
Earth’s Interior: Methods of Study
- Surveys and Mines: Limited to a depth of 13 km compared to Earth’s radius of 6371 km.
- Study of Rocks: Natural processes like erosion and volcanic eruptions bring interior rocks to the surface.
- Meteorites: Provide insights into solar system materials, similar to Earth’s composition.
- Seismic Methods: The most effective, analyzing seismic waves from earthquakes or blasts.
Seismic Waves: P and S Waves
- P Waves (Primary): Faster, travel through all mediums, faster in solids
Iberian Peninsula: Mountain Ranges and Geology
Mountain Ranges of the Iberian Peninsula
The mountainous Chimes Plateau originated in the Tertiary period through the rejuvenation of blocks or by the folding of material deposited by the sea during the Secondary Era at the edges.
a) Galaico-Leonese Massif
Located in the northwest corner of the plateau, it fractured and rejuvenated due to the Alpine orogeny. It features both Paleozoic materials and mountains with rounded tops and low elevation (Segundera, Ancares). The massif ends in steep slopes.

Causes of Wind
Atmospheric pressure differences (pressure = Force/area). Average pressure at sea level: 1 atm = 29.92 inHg = 14.7 psi.
Types of Windmills
- Small (<10 kW) – Home, farm, remote applications (telecommunications, water pumping)
- Medium (10-250 kW) – Village, hybrid, distributed power
- Large (250 kW-2 MW) – Central wind farms, distributed power
Factors Affecting Wind Power Generation
In order of importance: [Power in wind = 1/2ρAV3] A = Swept area (πR2); V = Wind speed;

Sustainable Cultivation Practices
Polyculture and monoculture: Agricultural spacing is divided into multiple parts. Different species are grown. Monoculture is a specialized agricultural crop with a single product.
Irrigation and scanning: In the landscapes of water extraction, irrigation of the subsoil, and through channels, sprinklers, etc., the fields are driven by a shaft. The crops in principle scan alone and are supplied with water, but it is a frequent technical practice of irrigation in traditionally

Argentina’s Boundaries and Frontiers
Boundaries and frontiers of Argentina: This is where one country ends and another begins. On maps, it is represented by a line.
In the field, the limit can be represented by:
- River: A river boundary.
- Mountains: The limit is orographic.
- Straight lines: A geometric limit.
- Parallel and Meridian: Geodetic.
Argentina’s Borders: A Zone of Cultural Exchange
Borders: The strip of land that straddles the international boundary. It is an area where the definitive characteristics

Convergence: Ocean Between Two Plates
When oceanic lithosphere cools and thickens as it moves from a ridge, it eventually breaks and subducts. Characteristics of subduction zones:
- Great bow
- Intense magmatism resulting in volcanic islands
- Tectonic erosion
- Merging of oceanic crust into the sublithospheric mantle
- Low pressure from the overriding plate on the subducting plate, leading to:
- Easy subduction of sediments
- Formation of a deep ocean trench
Convergence: Oceanic and Continental Lithosphere
