Universe History, Planet Formation, and Continental Drift
History of the Universe
1. Inflation
The universe expanded rapidly.
2. Formation of Matter
The universe was composed of subatomic particles bathed in a lot of energy called photons. When they cooled, they formed neutrons and protons.
3. First Atoms
Approximately 300,000 years after the Big Bang, hydrogen and helium atoms formed.
4. The Ignition of the Universe
Charged particles interfered with the photons. But, as atoms formed, light could travel freely through the newly created space. The universe became

Despite pests, the development of various ecosystems is favored by environmental conditions. These include:
- Shrubs: chilcas, foxtail
- Trees: chan, carob
- Animals: snakes, lizards, foxes, birds, insects
Xero Tropical Forest Region
Located within the absolute desert, this region features possible groundwater reservoirs and the Prosopis Tamarugo tree. Sheep and cattle are also present.
Andean Highlands
North of 23 degrees latitude, this region is influenced by a monsoon climate with summer rainfall. The landscape

Environmental Rhythms
Living things respond to environmental changes. Rhythmic movements are also important.
- Diurnal Rhythms: Organisms comply with these changes by altering their periods of rest and activity.
- Seasonal Rhythms: A wide range of behavior is associated with seasonal changes.
- Tidal Rhythms: Changes in sea level periodically affect organisms living on the coasts.
Regeneration After Fire
In a fire, only some underground elements and seeds survive, and the soil suffers significant damage. If

**Factors Influencing Water Resources in Spain**
Several factors influence the availability and distribution of water resources in Spain:
- Weather: Plays a crucial role in determining the quantity and distribution of water in rivers, lakes, and aquifers. Precipitation patterns create a contrast between “wet Spain” (with sufficient precipitation) and “dry Spain” (with pronounced summer droughts).
- Relief and Topography: Influence the organization of watersheds, the erosive capacity of rivers and lakes,
Landform Evolution: Rivers, Torrents, Wind, Sea, and Glaciers
River Landforms and Processes
Rivers shape the landscape through erosion and deposition, creating distinct landforms:
- V-shaped valleys: Formed by rivers with high erosive power, cutting deep into the ground.
- Flat-bottomed valleys: Develop as rivers slow, meander, and widen their valleys.
- Peneplains: Result from the merging of river valleys, creating a broad, flat surface.
River systems also produce:
- Hills witness: Isolated remnants of older plains.
- Terraces: Stepped landforms representing successive valley
Anthropology: Biological, Sociocultural, and Philosophical Dimensions
Anthropology
Anthropology is a broad discipline that emerged in the 19th century. It incorporates knowledge from various fields, including physics, chemistry, biology, genetics, paleoanthropology, sociology, cosmology, and philosophy, among others. Establishing different responses can be risky when dealing with human beings. If a problem is reduced to a single reality, the solution is also reduced to a single reality, which can lead to a reductionist approach. Anthropology must incorporate knowledge
