Renewable Energy Sources: Untapped Potential
Hydraulic Power
Hydropower is generated by the falling mass of water to save a difference in level. Currently, it is used to generate electricity in power plants. Reservoirs and dams are associated to retain the water and create the necessary gap for the fall of the water.
Advantages
- Minimum maintenance cost.
- It does not pollute.
- Favors navigable rivers.
Disadvantages
- Geographical limitations.
- High cost.
- Sometimes it creates social conflicts.
Tidal Energy
It is based on the exploitation of tidal currents.

Electrical Circuits
Electric current is formed by electrons jumping from one atom to another, and this movement generates electricity.
Voltage is the potential difference that makes the electric current flow through a conductor. A potential difference, tension, or voltage must exist for electric charges to move through a conductor in a given time.
Ohm’s Law
- Current = Amps = I
- Voltage = Volts = V
- Resistance = Ohm = R
In a continuous electric circuit, electrical power is produced by the movement of electrons.

Catalonia’s Climate Zones
- Mediterranean Trend (Continental): Located west of the Central Depression. Characterized by wider thermal oscillation and scarce rainfall with prolonged drought periods.
- Oceanic Climate: Found in the Vall d’Aran, influenced by the Atlantic. Features mild temperatures and frequent rainfall throughout the year.
- Mountain Climate: Situated in the highest peaks of the Pyrenees and their foothills. Experiences low temperatures and abundant rainfall. Includes downhill (above 2,300
Understanding Rocks, Weathering, and Limestone Landscapes
Rock Types: Igneous, Sedimentary, and Metamorphic
1. Igneous Rocks: Formed from volcanic activity. They are made of tiny crystals that formed as the volcanic rock cooled down. Examples include granite and basalt.
2. Sedimentary Rocks: These rocks are laid down in layers. They are made of other rocks that have been eroded and transported, or from the remains of plants and animals. Examples include limestone, chalk, and coal.
3. Metamorphic Rocks: These are rocks that have been changed due to intense

Morphostructural Units of the Iberian Peninsula
In the document, map 1 shows eight identified locations. For each, we will indicate:
- (a) The morphostructural unit to which it belongs.
- (b) The dominant crag type (siliceous, calcareous, or clay).
- (c) Whether the morphology is ancient, recent, or very recent (with justification if necessary).
- A: Sierra Carrasqueta:
- (a) Subbetic System.
- (b) Predominantly Mesozoic limestones.
- (c) The Subbetic System is somewhat later than the Penibetic, originally beginning
Material Buildings: Structure, Materials, and Properties
Building Structure
Skeleton: The foundation, beams, and pillars form the building’s skeleton.
Enclosures: These protect the building from external atmospheric agents.
Partitions: Walls and dividers constructed from bricks and plaster.
Coatings: Finishes such as paint and roofing.
Natural Stone Materials
Natural stone is categorized by origin:
- Magmatic or Igneous Rocks: Originating from within the earth, these rocks have a grainy texture and are typically light in color and hard.
- Sedimentary Rocks: Formed
