Spain’s Diverse Landscapes: Siliceous, Limestone, Clay
Siliceous Spain
Silicea consists of ancient rocks from the Precambrian and Primary eras. Therefore, they are in the western mainland and have branches to the western part of the Cantabrian Mountains, the Central System, the Montes de Toledo, and Sierra Morena. There are outcrops in the axial zone of the Pyrenees, the Sistema Ibérico-Catalan coastal mountain range, and the Penibaetic System. In this area, the rock is predominantly granite. The modeling is determined by the characteristics of this

Ecosystems and Their Resources
An ecosystem encompasses all living beings inhabiting a given area and their relationship with their environment. Large ecosystems are known as biomes.
Resource Depletion
Renewable resources are energy sources like wind, solar, and biomass. If the consumption rate exceeds the renewal rate, it leads to resource exploitation.
- Nuclear fuels provide substantial energy from small quantities of radioactive material.
- Mineral resources require a high concentration of minerals for
Construction Techniques: Lattice Frameworks
Lattice frames are carpentry works that form the sturdy frame or skeleton of a set or design element. Frames can be vertical, horizontal, or inclined. In each of these cases, they are called:
- Vertical: Lattice walls.
- Horizontal: Lattice floors and ceilings.
- Inclined: Lattice deck.
Horizontal Components of a Lattice
Carrera – A horizontal beam placed on walls and designed to support other parts or to link buildings; for example, beams that constitute the forging of the floors.
Lintel – A timber that
