Magma and Igneous Rocks: Formation, Types, and Mineral Deposits
Magma and Igneous Rocks
Magma: is a portion of earth material in a liquid state, which can contain components in gas or solid state. The solidification process of magma results in magmatic rocks.
Plutonic: Magma that solidifies slowly inside the crust allows minerals to crystallize slowly.
Filonian Magma: Rising magma may melt surrounding rocks.
Volcanic: These are rocks resulting from magma rising through cracks and reaching the surface.
Texture of Igneous Rocks
Grainy: The components are well differentiated

Energy Resources
The economic system and our way of life depend on the growing consumption of energy in all human activities. This energy dependence faces two basic problems: the depletion of nonrenewable energy sources and the impacts of widespread energy use. Energy is divided into renewable and nonrenewable types.
Environmental Impact
An environmental impact is a positive or negative effect produced by an activity on the environment, although the term often has a negative connotation.
Deforestation
Forests

In general, human action on ecosystems produces an effect of simplification or reduction of immature ecosystem states, resulting in decreased diversity. According to a general environmental law, this results in a decrease in stability. The most important effects of this action are the extinction of species, destruction of natural ecosystems replaced by social ecosystems, and pollution. These events have further highlighted the need for holistic approaches and integrated science as ecology because

Kinetic Theory of Gases
The kinetic theory of gases states that gases are formed of very small particles separated from each other, moving constantly. Gases occupy the entire volume of the container. Gas pressure is exerted on the walls of the container due to the constant collisions of the gas particles with the walls.
The more rapidly the particles move, the higher the temperature. Solids do not expand or compress easily, maintaining a constant volume and shape. Their particles are strongly united

Factors Influencing the Iberian Peninsula’s Climate
Geography:
Latitude: The Iberian Peninsula is located in the temperate zone, which results in two clearly marked seasons and two transitional seasons. Its position in southwestern Europe means it is affected by the zonal circulation of the West.
Maritime Influence: The location between two seas influences temperature regulation, helping to create mild climates with lower temperature ranges. The Mediterranean Sea has higher temperatures than the Atlantic,

Geological and Geographical Definitions
- Appalachian Relief
- A type of folded structure rejuvenated by erosion that highlights hard materials and depresses soft layers (e.g., Montes de Toledo).
- Germanic Relief
- Relief where the hardness of materials led to fracturing or faulting. Characterized by horsts and grabens (rifts).
- Jurassic Relief
- A type of folded structure formed by anticlines and synclines.
- Saxon Relief (or Fold-Fault Relief)
- A mixed relief type involving both folding and fracturing.
- Igneous Rock
- Rocks
