Spain’s Diverse Climate: From Mediterranean Coasts to Mountain Peaks
Weather in Spain
Spain’s diverse weather patterns are influenced by its latitudinal position on the Iberian Peninsula and its location within the atmospheric general circulation. Air masses from both north and south bring varied characteristics, resulting in hot and cold, humid and dry conditions. This temperate zone experiences a mix of warm and cold air, leading to remarkable climatic diversity across its varied terrain.
Oceanic Climate
The oceanic climate dominates northern and northwestern Spain.
Tracing Human Evolution: From Early Primates to Homo Sapiens
II.2.2. Human Evolution
Geologists divide Earth’s history into eras, periods, and epochs. Life began about three or four billion years ago. Around 600 million years ago, the first animals large and hard enough to leave abundant fossils appeared. The phylum of chordates, the subphylum of vertebrates, and the superclass of tetrapods were present in the Devonian Period (300-400 million years ago). Mammals appeared during the Mesozoic Era (200-150 million years ago). Towards the late Mesozoic or early

1.1 Origin of Asphalt
Bitumen, a blackish-brown substance with a consistency ranging from semi-solid to solid, is a byproduct of oil refining. It’s a mixture of hydrocarbons completely soluble in sulfide. Bitumen is processed to remove impurities, resulting in asphaltic bitumen, the base material for various asphalt types.
Bitumen Classification by Origin
- Natural: Natural oil seeps onto the surface, forming lakes. An example is Trinity Lake in Venezuela.
- Artificial: Derived from oil refining. Not
Sustainable Energy, Volcanic Risks, and Geosphere Resource Management
Energy Policy Principles
6. What are the basic principles which should underpin energy policy in the coming decades to prevent a collapse of development?
- Demand-side management: Combine progressive price increases with citizen education to reduce consumption and waste.
- Promote reuse and recycling: Organize waste collection networks and support businesses engaged in these technologies.
- Gradual replacement of non-renewables: Support renewable energy initiatives at community, state, and government levels.
Understanding Soil Erosion: Types, Causes, and Control Methods
Erosion: Definition
Erosion is the physical process of soil evolution involving movement and displacement of soil materials. It is caused by water, wind, temperature changes, biological activity, and human interference.
Types of Erosion
Natural Erosion
This is normal erosion occurring due to natural forces.
Induced or Accelerated Erosion
This type of erosion is caused by the combined action of natural forces and human activities. It is often faster than natural erosion due to land mismanagement.

Chemistry Through History
Chemistry has been used since ancient civilizations in activities like cooking and metallurgy. Egyptians and Babylonians achieved great perfection in applying techniques, being masters in handling metals, glass, gold, silver, and clay. However, these peoples gave little importance to the theoretical basis of the processes they carried out daily.
In the 6th century BC, thanks to the emergence of theories about matter through philosophers like Thales of Miletus (625-545 BC)
