Plateresque, Purism, and Herrerian Styles in Spanish Architecture
Plateresque Style in Spanish Architecture
The Plateresque style is a fine decorative style that covered the facades of buildings. It is characterized by the following:
- Elements and survival of late Gothic structures (ribbed vaulting, archways)
- Mudejar elements: persistence of ceilings and medieval structure of buildings
- Abundant decorations (medals, garlands)
- Appearance of representative works, such as altarpieces
A typical example is the facade of the University of Salamanca. It resembles a front-altarpiece

Earth’s Relief Classification
- Mountain: Relief over ten degrees with a large gap between the top and its base.
- Hill: Relief with little unevenness.
- Gorge or Throat: Narrow valley featuring steep walls on its sides.
- Plateau: Relief with a flat top.
- Terraces: Graduated relief.
Interpretive Rating of Relief Forms
Some terms are:
- Mountain: Relief that stands out from contiguous areas, formed by the folding of materials or volcanic activity.
- Witness Hill: Relief that, at peak height, is not at the same level
Understanding Metals and Plastics: Properties & Processes
Metals
Metals are usually obtained from the transformation of minerals, which are rocks extracted directly from nature.
Some metals, such as gold, silver, platinum, and copper, can be found in their purest form and are called native metals.
Physical Properties
Electrical conductivity is the property that allows the passage of electrical current.
Thermal conductivity is the property of materials to transmit heat.
Density is the amount of material mass per unit volume.
Expansion is the relative variation

Natural Materials: Materials used as found in nature.
Processed Materials: Materials obtained by subjecting natural materials to various chemical processes.
Synthetic Materials: Materials obtained by chemical methods from other materials.
Technical Use Materials
Wood: Derived from tree trunks, strong, elastic, good heat and electrical insulator. Comes in natural (pine) and processed (plywood) forms.
Paper and Cardboard: Made from wood pulp, easy to cut, fold, sew, and dye. Available in various types

Key Meteorological and Climatological Terms
Time and Climate
Time refers to the atmospheric conditions at a specific moment. Climate is the sequence of weather types that occur over a period of 30 years of observation in a given territory. Meteorology is the science that studies weather, while climatology studies climate.
Jet Stream and Action Centers
A jet stream is a strong wind current with a tubular structure, circulating between 9-11km in altitude. No difference exists between the equatorial and

Precambrian Era: From Earth’s Origin to 570 Million Years Ago
Hadean Eon
- Earth separated into three layers.
- The first atmosphere was formed.
- Meteorites continually bombarded the Earth.
- The Moon was formed.
- The first life forms probably existed at the end of the Hadean.
Archean Eon
- Few rocks remain from this eon.
- Almost all of the Earth was an ocean, with only microcontinents.
Proterozoic Eon
- Supercontinents were formed, and lithospheric movement was similar to that of today.
- Meteorite bombardment stopped.
- Tectonic
