Non-Renewable Energy
Types of Coal
| Type | Anthracite | Bituminous Coal | Lignite | Peat |
|---|---|---|---|---|
Percentage Carbon | 95% | 85% | 75% | 50% |

Coke Production
Coke is obtained from coking coal. The coal is introduced into closed chambers. The temperature is increased to about 1100ºC for about 16 hours, after which it is transferred off the tower.
Thermal Power Plant Operation
Coal is pulverized and introduced into the boiler, where it is

**Stratigraphy**
Stratigraphy is the study of layered (stratified) rocks, primarily sedimentary rocks, focusing on their composition, origin, age relationships, and geographic extent. However, it also applies to certain igneous rocks, such as layered lava flows or volcanic ash beds, which follow the principles of stratigraphy. Additionally, some metamorphic rocks exhibit stratification and can be studied using stratigraphic principles.

Precautions in Demolition Abatement
It is very important to study the structure. Dimensioning the cable is important because it can divide the costs. Instead of demolishing, cutting, and charging a beam. The cable resistance must be greater than the building. To this end, a backstop to distribute charges (in the wave barrier is placed metallic cable).
Security Mechanism: F1R > F2 > F demolition, being F1R carder breakage.

**Deciduous Forest**
Deciduous forests are forests of deciduous trees that lose their leaves in the winter. They are typical of northern Spain, where hardwood forests such as beech and oak thrive.
**Desertification**
Desertification is the process that leads to a breakthrough in the area of desert soil misuse by inappropriate farming practices, resulting in the loss of vegetation. Currently, a wide area in the Peninsula is in danger of desertification, especially the southeast area: Almeria and Murcia.

Water Balance
Water balance: Rain = surface runoff + evaporation + underground runoff. In a lamb, regional inputs and outputs are always balanced.
Basin
A basin is an area of land where water and sediments drain into a common riverbed. It is a natural formation with magnificent hydrogeological, physical, chemical, and biological properties that make up various common elements (climate, etc.). It is formed by many water currents and increases the water below.
It starts in small streams, to rivers, and

Mineral and Energy Resources of the Geosphere
The resources of the geosphere can be divided into mineral and energy resources. Among the latter, we will study fossil fuels, nuclear energy, and geothermal energy.
Mineral Resources
Mineral resources constitute a vital resource to sustain industrial activity. Given their non-renewable nature, there is a constant search for new sources as those that have been exploited are depleted.
Types of Deposits
- Deposits of foreign origin are found in sedimentary rocks,
