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

Natural Disasters and Public Works

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

Exploring Earth’s Atmosphere: Layers, Variables, and Phenomena

Earth’s Atmosphere

Atmospheric Layers

The atmosphere extends up to 1000 km from Earth’s surface and is divided into five layers:

  • Troposphere: Extends approximately 13 km in altitude, with varying thickness (16 km at the equator, 7.8 km at the poles). Contains water vapor and is where most weather phenomena occur. Temperature decreases 6.5°C per 1000 m. The tropopause marks the transition to the stratosphere and is associated with the jet stream.
  • Stratosphere: Extends from 13 km to 50 km in altitude.

Construction & Demolition Waste: Definitions & Management

Construction & Demolition Waste

Definitions and Categories

According to Law 10/1998 on waste, waste is defined as any substance or object belonging to categories listed in the Act’s annex and discarded or intended for discard by the holder. The European Waste Catalogue (EWC) provides further categorization.

Waste Categories (Law 10/1998):

  • Q1: Production or consumption not specified below.
  • Q2: Substandard products.
  • Q3: Expired products.
  • Q4: Accidentally spilled or contaminated materials.
