Human Culture: Key Factors and Social Learning
Humanizing Factor: Culture
Culture is a main humanizing factor. In the process of hominization, over millions of years, not only is the production of hominization important, but also culture is in everything and produces humanization. The social realm determines the appearance of culture. If we consider that the biological and genetic connection with the world is our natural dimension, then we can consider culture as the set of information acquired through social learning. Therefore, animals would

Characteristics of the Spanish Peninsular Relief
The relief is the set of forms presented by the Earth’s surface, which are dynamically constructed and destroyed. It is solid-form and determined by the width and extension of the coast. The rectilinear layout offers few refuges for navigation. The high average altitude is due to the extensive existence of a central plateau, and mountain ranges that cross the peninsular territory. The average altitude is 660m, with some areas reaching 1300m, making

Abiotic and Biotic Factors in Ecosystems
Conditions or Environmental Factors in One Place
Abiotic Factors
- Physics: Light and shadow, wind, barometric pressure, altitude, solar radiation.
- Chemicals: The amount of air and soil water, salinity, dissolved oxygen.
Biotic Factors
- Intraspecific: Family association, colonial, social, gregarious.
- Interspecific: Mutualism, commensalism, renters, predation.

Waterborne Diseases
Water serves as a transport agent for pathogens eliminated by humans through manure.
Biological Agents (Ingestion)
- Typhoid
- Paratyphoid
- Cholera
- Giardiasis
Chemical Agents
- Fluorosis (excessive fluoride)
- Lead Poisoning
- Metahemoglobinemia (nitrate)
Water Quality
- Physical impurities: related to color, odor, and flavor.
- Chemical impurities: dissolved substances resulting from the presence of water.
- Biological impurities: pathogenic microorganisms (viruses, bacteria).

Terrestrial Biomes: Climate, Altitude, and Vegetation
The distribution of living beings on the Earth’s surface in the ecosphere is conditioned by several factors, including climate, mountain barriers, soil type, altitude (height above sea level), and latitude (distance to the Equator). The most significant factor is the weather, which is determined especially by temperature and precipitation.
Altitude and latitude affect temperature and precipitation. The main terrestrial biomes on the planet are:
- Tundra
- Taiga
- Grassland
- Desert
- Laurisilva
- Mediterranean forest
- Deciduous
