Mining resources in the world and in Spain

Mining resources are raw materials that have a mineral origin, although they can also be of vegetable origin (coal, petroleum). They belong to the primary sector as they are raw materials, but they are the foundation of industry (secondary sector) because they provide the minerals and the sources of energy that the secondary sector needs.

Mining areas in the world

Coal is found in the basins next to the mountain ranges that were formed some 300 million years ago, such as the Appalachians or the Ural Mountains, and other places in China, Europe and Australia.
Oil is found mainly in the countries near the Persian Gulf, the Gulf of Mexico, Venezuela, Russia, and other countries, and is often found in close... Continue reading "Mining and Energy Resources: Global Overview and Impact on Industry" »

Protecting Earth's Resources and Ecosystems

Water Pollution and Contamination Risks

Rivers and lakes have less water volume than the seas, making pollution a very serious threat. If there is a toxic spill, the concentration of hazardous substances can be high. These substances will affect the entire river or lake, leaving the water unusable.

Vulnerability of Groundwater Sources

Aquifers: These underground reservoirs take many years to recharge or refill with water. If a pollution incident occurs, it could take a hundred years or more before the contaminant is eliminated. During this time, the contaminated water will flow into the rivers, lakes, and wells that draw water from the aquifer.

Solutions to Water Pollution

Effective strategies involve a... Continue reading "Protecting Earth's Resources: Water, Soil, and Biodiversity Conservation" »

The Age of Exploration, spanning from 1400 to 1750 A.D., marked a transformative period in European history. During these years, European perceptions of the world underwent a dramatic shift as explorers ventured into previously uncharted territories. Before this era, European understanding of the world was limited, with prevailing beliefs that the Earth was flat, the southern seas were boiling, and the world was smaller than it actually is. Additionally, religious motivations played a role, with the spread of Christianity against Islam being a significant factor.
