Stratigraphic Classification and Correlation Methods
Categories of Stratigraphic Classification
Lithostratigraphic units – Units based on the lithologic properties of the rock bodies. Unconformity-bounded units – Bodies of rock bounded above and below by significant discontinuities in the stratigraphic succession. Biostratigraphic units – Units based on the fossil content of the rock bodies. Magnetostratigraphic polarity units – Units based on changes in the orientation of the remanent magnetization of the rock bodies. Chronostratigraphic units – Units

Clean Technologies vs. Cleaning Technologies
Read More1. Differences Between Clean and Cleaning Technologies
- Cleaning Technologies (Clean-Up Technologies): These technologies aim to reduce environmental impact by modifying or adding processes at the end of the production line (end-of-pipe). They are always implemented in an already established process or facility.
- Clean Technologies: These involve conceptual or procedural changes in the manufacturing of products and human activities aimed at preventing environmental
Geomorphology: Landforms, Processes, and Earth’s Evolution
What is Geomorphology?
Geomorphology is the study of landforms, the processes that create and alter them, and the landscape evolution of the Earth. It examines how physical, chemical, and biological processes shape the Earth’s surface, resulting in various materials and landforms. These landforms and materials serve as a record of Earth’s surface history.
Geomorphology is a broad, interdisciplinary field encompassing geography, geology, and earth and environmental sciences. It includes many subdisciplines,

The Southern Sub-Plateau
The southern sub-plateau is lower, with a height between 500-700m. It is divided into two plateaus separated by Toledo, which corresponds to the divide between the two rivers: the Tagus River to the north and the Guadiana River to the south. This sub-plateau is inclined toward the Atlantic.
Units Related to the Plateau
- Ancient Paleozoic base reaching the sea: León, Zamora, and Extremadura.
- Sedimentary basins with sedimentary rock materials.
- Interior plateau ranges formed during
Water, Landfills, and Environmental Impacts: Resource Analysis
Water Resources and Availability
Water resources are not fully exploitable in a watershed. Some rainwater flows to the sea or is lost through evaporation or infiltration into hard-to-reach aquifers. Total water resources are the volume of water a basin receives annually. Available water resources are the amount that can be used for industrial, agricultural, etc. purposes.
The relationship between total and available water varies by basin, mainly due to weather. Northern basins generally have more

Water Uses
Consumptive Uses
- Industry: Raw material for chemical synthesis, refrigeration, steel production, waste transport, cleaning, and steam generation for electricity.
Non-Consumptive Uses
- Energy: Hydroelectric power generation.
- Recreation: Sports and leisure in rivers, reservoirs, lakes, and the sea. Includes primary contact (baths, spas) and secondary contact (landscape, navigation).
- Ecological and Environmental: Wetlands and lagoons as habitats for plants and animals, havens for migrating birds,
