Understanding Tectonic Plates and Ocean Formation
Characteristics of Oceanic Ridges
The oceanic ridge is an undersea mountain range rising above the abyssal plain. Its route is interrupted by lateral fractures called transform faults.
Seabed Ages
1) Existing rock at the ridges: Basalts at the oceanic ridges are less than a million years old.
2) Older oceanic crust separating from the ridge: The age of basaltic rock increases as we move away from the ridge.
3) Sediment thickness related to seafloor age: The ridge is devoid of sediment.

Uniformly Intrinsically Safe System
A nuclear reactor is a shielded device producing controlled nuclear reactions for energy, fissile material, or research. It minimizes environmental impact and radioactivity through careful material selection. While emitting no harmful gases, it produces long-lasting radioactive waste.
Current research focuses on:
- Inertial confinement: Fusion via particle or laser beams.
- Magnetic confinement: Fusing material in a magnetic field to achieve necessary temperature and
Understanding Energy: Sources and Systems
Energy Essentials
Energy is essential for all events in the universe, from planetary motions to the activities of living beings. It drives tectonic movements, the water cycle, and ocean currents.
Energy Use
Energy is a necessity for all living organisms. Humans utilize two forms of energy:
- Internal energy (endosomatic): Energy consumed for body maintenance.
- External energy (exosomatic): Energy used for operating devices and machines, enabling lighting, heating, transportation, etc.
Energy Systems: Primary

Item 2: Iberian Peninsula Relief Features
The Iberian Peninsula exhibits three primary features:
- Massive Form: The peninsula’s substantial width from west to east, with minimal coastal irregularities.
- High Average Altitude: An average elevation of 660 meters due to the presence of high mountains and an extensive upland core, the Plateau, with altitudes between 600 and 800 meters.
- Peripheral Mountainous Terrain: Surrounding the Plateau, curbing maritime influence and creating a stark contrast between
Understanding Spain’s Climate: Factors and Regional Variations
Factors Determining Spain’s Climate
The climate of a particular place is determined by numerous factors, such as the Earth’s translational motion and rotation, creating seasons, days, and nights. Geographical and thermodynamic factors also contribute to climate variations. Geographical factors include altitude, latitude, the influence of the sea, and relief.
- Altitude: Higher altitudes experience lower temperatures, with a decrease of approximately 0.6°C for every 100 meters.
- Latitude: Sunlight affects
Aquatic and Terrestrial Ecosystems: Factors and Interactions
Life in Aquatic and Terrestrial Environments
Environmental Factors
Salinity
Plants often prefer neutral soil, though some, like pine, thrive in slightly acidic conditions, while others, like beech, prefer alkaline environments. Aquatic life is significantly affected by salinity. Freshwater contains less than 5g/L of salts, while saltwater in seas ranges from 33 to 37g/L. Brackish water, found in some inland areas, has an intermediate salt concentration. Most aquatic species can only survive in either
