Relief Formation and Landscapes of the Iberian Peninsula
Relief of the Iberian Peninsula
The relief found in the Iberian Peninsula is the result of a series of orogenic stages and erosion that have alternated over millions of years. There are three types of Iberia: siliceous, limestone, and clay.
Siliceous Iberia
First, in siliceous Iberia, there are Precambrian and Paleozoic materials (the oldest in the Peninsula). These are igneous or magmatic rocks (resulting from cooling lava) and metamorphic rocks (formed from the transformation of igneous and sedimentary

- Abrasion: Erosion caused by the sea, creating a flat coastal area.
- Albufera: A saltwater lake separated from the sea by a barrier island.

Volcanoes
A volcano is any crack in the Earth’s surface through which incandescent material emerges from within.
Some well-known volcanoes are:
- Teide, Spain
- Vesuvius, Italy
- Parinacota, Chile
Some volcanoes are conical mountains, while others are in the deep sea and are shaped like cracks.
Why Do Rocks Melt?
At about 100 km depth, the temperature is 1300°C. Despite the high temperatures inside the Earth’s crust and mantle, rocks are in a solid state. The rocks melt due to:
- Temperature: In this area, it is
Waste Management: Types, Impacts, and Sustainable Solutions
Types of Waste
There are various types of waste, each with unique characteristics and disposal requirements:
- Agricultural: Stems, leaves, straw.
- Ranchers: Manure and slurry.
- Forest: Scrap wood, branches, thinning leaves, sawdust, wood chips, and remains of burnt wood from fires.
- Mining: Sterile mining byproducts.
- Industrial:
- Inert: Scrap, sand.
- Assimilated to urban: Plastics and papers.
- Toxic and hazardous: Chemicals.
- Radioactive: High-level or low-level waste.
- Municipal Solid Waste (MSW):
- Waste originating
Rock Formation and Metamorphism: An In-Depth Look
1. The Cycle of Rocks
Internal processes lead to the formation of new rocks and the formation of relief. External processes cause wear, sediments are deposited in the basins, and new rocks are formed. The geological cycle describes the geological processes that contribute to the generation of rocks, acting upon each other in a succession of events, ordered or not.
Milestones:
- Orogeny: Mountain range formation, relief, and inner strength from within to the exterior.
- Gliptogenesis: Destruction of geological
Human Impact on Natural Systems: Climate Change and Biodiversity
**Human Intervention in Natural Systems**
_Homo sapiens_ underwent a type of development and evolution based on science and technology that allows us to use nature and science to meet our needs. We can transform nature beyond what corresponds to the biological scale. The adaptive success of our species has replaced cultural evolution with biological evolution. Civilization:
- Consumes increasing amounts of energy
- Exploits natural resources
- Degrades exhaustible natural resources with their wastes, impacting
