Geological Evolution of the Iberian Peninsula
Precambrian Era
The Iberian Peninsula was located between the African (Gondwana) and European (Laurasia) continental plates, separated by the Tethys Sea. Orogenic movements during this era had minimal impact, primarily affecting the Galician-Leonese Massif, the western Asturian-Leonese Massif, and parts of the Toledo Mountains and Central System.
Paleozoic Era
The Hercynian orogeny, characterized by strong lateral pressures, began during the Carboniferous period. This resulted in the formation of mountain

Temperature and Precipitation
Temperature Range
The difference between maximum and minimum temperature is called the daily thermal amplitude if measured daily, and the annual temperature range if measured annually. This is calculated by finding the difference between the warmest and coldest months.
Average Temperature
The average temperature is calculated by adding the maximum and minimum temperatures and dividing by two. This can be done monthly or yearly.

Specialty Mortars
Industrial Mortars
Industrial wet mortar is a pre-mixed, ready-to-use product. Its components—conglomerates, sand, water, and/or additives—are precisely measured and mixed at a factory. This ensures consistent quality and cost-effectiveness. The additives maintain workability and prevent drying, making it ideal for various applications.
Cement Screed
: are special rules for land for new or restoring beams are dry mortars, cements and special additives. It comes in powder ready

1. Natural Resources
What are Natural Resources?
Natural resources are the various elements of nature that humans utilize for their benefit.
Human Exploitation of Natural Resources
The phrase “mankind increases the exploitation of natural resources far above their growth” highlights the fact that humanity’s consumption of natural resources exceeds the rate at which these resources can replenish themselves. This is known as overexploitation. Examples include the overuse of oil despite its long formation

Rock Deformation
Deformation is the change in shape or volume experienced by rocks undergoing stress.
Types of Deformation:
- Elastic: The material deforms when subjected to stress but recovers its original shape when the stress stops.
- Plastic: The material deforms when subjected to stress and does not regain its original shape when the stress ceases to act.
- Brittle: The stress causes the material to lose internal cohesion and fracture.
Changes in Rock Behavior
At high temperatures and in the presence of
