Natural Hazards
Geological Hazards
Earthquakes
Earth tremors in Spain are due to the peninsula’s location at the edge of the African and Eurasian plates. This subduction zone makes the South and Southeast the areas with the highest seismic risk.
Volcanic Eruptions
The Canary Islands are the only area with currently active volcanoes in Spain.
Slope Movements
These are rapid movements of large masses of earth and rocks down a slope. They are characteristic of humid regions

The Origin of the Universe
The Sun, an ordinary yellow star, orbits the outskirts of the Milky Way galaxy. Galaxies are vast clusters of billions of stars, held together by gravity. Before the universe existed, there was nothingness. The Big Bang theory proposes that the universe originated from a massive expansion of elementary particles. Initially, the universe was filled with positive particles colliding in a sea of photons. Through the interaction of protons and neutrons, which attracted electrons,

Sculpting the Relief · Mountains, rivers, glaciers, and wind modify the relief, acting as geological agents. These processes are activated by solar energy, which favors the evaporation of water and allows for rain and gravity to play their roles. External geological agents and actions are involved in these processes, while internal processes are caused by the heat inside the Earth. Factors Affecting Relief Shape. Land surface processes take form through the modeling of the relief: • Each type

Types of Earthquakes
Earthquakes and Plate Tectonics
Converging Areas:
- Zones of seismicity and largest earthquakes with higher magnitudes.
- Convergence between two continental plates can form mountain ranges.
- Convergence between oceanic and continental plates leads to the formation of an ocean trench where subduction occurs. The oceanic plate (denser) subducts under the continental plate.
Divergent Zones:
- Earthquakes associated with mid-ocean ridges.
- Located in rift parallel faults.
- Earthquakes of lower magnitude
Climate and Weather Factors in Spain and the Canary Islands
Climate Factors
Climate factors are those aspects that influence permanent and unchanging climate.
1. Geographical Factors
These include latitude, location, configuration, currents, and relief:
a) Latitude
Spain’s latitude, in the Northern Hemisphere’s temperate zone, determines the existence of two distinct seasons: summer and winter, separated by two transitional seasons, spring and autumn. In the Canary Islands, due to their location south of the temperate zone and proximity to the intertropical domain,

Eukaryotic Cells and Organelles
Eukaryotic cells, the most complex animal cell type, contain various organelles with specific functions:
- Ribosomes: Synthesize proteins.
- Endoplasmic Reticulum: Provides materials to the cell and destroys waste.
- Mitochondria: Carry out cellular respiration.
- Golgi Apparatus: Processes and packages proteins.
- Lysosomes: Perform digestion.
- Vacuole: Stores nutrients.
- Cytoskeleton: Provides cell shape and support (microtubules and microfilaments).
- Chloroplast (in plants): Contains
