Air Pollution: Characteristics, Effects, and Solutions
Characteristics of Issues
The nature, concentration, and physicochemical properties of a contaminant determine its impact. When a gas’s temperature exceeds the surrounding medium’s, it rises, facilitating dispersion. Higher altitudes increase the chance of bypassing thermal inversion layers, further aiding dispersion.
Atmospheric Conditions
Air temperature and its variation with height: These factors influence air mass movement and atmospheric stability. Temperature variations can lead to thermal

1. NIFE: The Earth’s Core
Q: In which part of the earth is NIFE found? What is it composed of?
A: The core of the earth is called NIFE. It is composed of Nickel (Ni) and Iron (Fe).
2. Pressure and Temperature in the Earth’s Interior
Q: What are the consequences of the pressure and temperature in the interior of the earth?
A:
- The temperature in the core ranges from 4400°C to about 6000°C.
- Pressure and density increase towards the interior of the
Factors Influencing Spain’s Diverse Climate
Factors Determining Spain’s Climate
Spain exhibits diverse climatic conditions shaped by various interacting factors.
Key Climatic Elements
The fundamental elements defining Spain’s climate are:
- Insolation and Cloud Cover: Spain receives substantial annual insolation, greater in the south and during summer. Cloud cover is inversely proportional to insolation, except in mountainous regions where winds contribute to cloud formation.
- Temperature: Average temperatures vary significantly due to latitude and
Factors Determining Weather in Spain
Spain is a country with a wide variety of climates, influenced by numerous factors that affect weather elements.
Key Elements of Climate
The key elements that shape Spain’s climate are:
- Insolation and Cloudiness: Due to its latitude, the Iberian Peninsula receives high annual insolation, with the south receiving more than the north, and summer exceeding winter. Cloudiness is generally inversely proportional to insolation, except in mountainous regions where dynamic wind phenomena tend to increase cloud
Metamorphic Rocks: Classification, Texture, and Formation
Metamorphic rocks are the result of the transformation of a pre-existing rock (protolith) due to changes in environmental conditions. This transformation occurs primarily in the solid state, involving recrystallization, mineral reactions, and structural changes, often facilitated by intergranular fluids. The main factors driving metamorphism are temperature, pressure, and chemically active fluids.
The classification of metamorphic rocks is based on their mineralogical composition, texture (grain

Earthquakes
Primary Waves (P-waves)
P-waves, or longitudinal waves, are oscillations where solid particles move in the same direction as wave propagation, with speeds between 6 and 13.6 km/s.
Secondary Waves (S-waves)
S-waves, or shear waves, arrive second, producing particle vibrations perpendicular to wave propagation, with speeds between 3.7 and 7.2 km/s.
Magnitude
The energy released during an earthquake.
Intensity
The effect of an earthquake on structures and people, measured by the Seismic Intensity
