Sample Castilla-La Mancha PAU Geology & Env Sci Practice Questions

Try these sample questions to review concepts for the Castilla-La Mancha PAU Geology & Env Sci exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which type of seismic waves are compressional (longitudinal) and propagate through both solid and liquid media in Earth's interior?
A.P waves (primary)
B.S waves (secondary)
C.Rayleigh waves
D.Love waves
Explanation: P waves (primary) are longitudinal compression and rarefaction seismic waves that travel at the highest speed and can pass through both solid and fluid media (liquids and gases).
2Which seismic discontinuity separates Earth's crust from the upper mantle at an average depth of 30-40 km beneath continental areas?
A.Gutenberg discontinuity
B.Mohorovičić discontinuity (Moho)
C.Lehmann discontinuity
D.Repetti discontinuity
Explanation: The Mohorovičić discontinuity (Moho) marks the physical and chemical boundary between Earth's crust (continental or oceanic) and the upper mantle, characterized by an abrupt jump in seismic wave velocity.
3At which type of tectonic boundary is new oceanic lithosphere created through basaltic magmatism?
A.Convergent boundary with subduction
B.Transform fault boundary
C.Divergent boundary or mid-ocean ridge
D.Continental collision zone
Explanation: At divergent boundaries (such as mid-ocean ridges), tectonic plates move apart and mantle decompression generates basaltic magma that rises, solidifies, and creates new oceanic lithosphere.
4Which volcanic (extrusive) igneous rock of mafic composition is the most abundant in the ocean basins?
A.Granite
B.Rhyolite
C.Andesite
D.Basalt
Explanation: Basalt is a fine-grained mafic volcanic igneous rock rich in pyroxenes and calcic plagioclase, and is the main constituent of Earth's oceanic crust.
5What is the name of the inclined seismogenic zone that marks the descent of a subducted oceanic plate beneath another plate?
A.Benioff-Wadati zone
B.Mid-ocean ridge
C.San Andreas transform fault
D.Continental rift trench
Explanation: The Benioff-Wadati zone is the inclined band of seismic hypocenters that defines the downward trajectory of the oceanic lithospheric plate as it subducts into the mantle.
6Which type of metamorphism is produced mainly by a strong temperature increase around a magmatic intrusion without high directed pressure?
A.Regional or dynamothermal metamorphism
B.Thermal or contact metamorphism
C.Dynamic or cataclastic metamorphism
D.Impact metamorphism
Explanation: Contact (or thermal) metamorphism is generated when an incandescent igneous mass intrudes into host rocks, transferring heat and creating a non-foliated metamorphic aureole (hornfels).
7What is the name of the fold whose oldest strata lie in the core and whose limbs converge toward the top?
A.Syncline
B.Normal fault
C.Anticline
D.Joint
Explanation: An anticline is a plastic deformation, convex upward, in which the oldest sedimentary strata occupy the central zone or core of the fold.
8Which European mountain range is a representative example of a continental collision orogen formed by convergence between the African and Eurasian plates?
A.The Andes
B.The Rockies
C.The Mid-Atlantic Ridge
D.The Alps
Explanation: The Alps represent a continental Alpine orogen formed by direct collision between the Apulian/African microplate and the Eurasian continent after the closure of the Tethys Ocean.
9According to Bowen's crystallization series, which is the first mineral of the discontinuous series to crystallize from a basaltic magma at high temperature?
A.Olivine
B.Quartz
C.Biotite
D.Muscovite
Explanation: In Bowen's crystallization series, olivine (an Fe-Mg nesosilicate) is the first mineral to crystallize in the discontinuous branch at temperatures above 1,200 °C.
10Which type of fault results from extensional tectonic stresses, where the hanging wall descends relative to the footwall?
A.Reverse fault
B.Normal fault
C.Tear or strike-slip fault
D.Thrust sheet
Explanation: Normal faults form under tectonic extension regimes; gravity causes the hanging wall to descend along an inclined fault plane relative to the footwall.

About the Castilla-La Mancha PAU Geology & Env Sci Exam

The Castilla-La Mancha PAU Geology and Environmental Sciences practice bank provides comprehensive preparation for 2º Bachillerato students sitting the Spanish university entrance exam administered by UCLM. It tests fundamental concepts in internal dynamics, surface processes, Earth materials and resources, ecosystem dynamics, natural hazards, and environmental management with regional context from Castilla-La Mancha (e.g., La Mancha aquifers, Ciudad Encantada karst, Almadén mercury deposits, Tablas de Daimiel wetlands).

Exam sponsor: University of Castilla-La Mancha PAU Tribunal. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

90-minute examination covering 5 core topic areas: Internal Dynamics & Plate Tectonics (25%), External Geodynamics & Surface Processes (25%), Earth Resources & Environmental Geology (20%), Biosphere, Ecosystems & Biodiversity (15%), and Environmental Management, Risks & Sustainability (15%).

Time Limit

90 minutes (1.5 hours)

Passing Score

Marked on a 0-10 scale. Minimum 4.0 required in Access Phase to combine with Bachillerato GPA (60% Bachillerato + 40% PAU Access Phase >= 5.0 to pass).

Exam / Certification Fees

EUR 52.99 base registration fee for PAU Access Phase (ordinary sitting, set by Universidad de Castilla-La Mancha).

Exam sponsor website

Fees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

Castilla-La Mancha PAU Geology & Env Sci: Suggested Study Strategy

1Master plate tectonic boundaries, seismic wave propagation (P, S, surface waves), and mantle convection models.
2Review regional external geodynamics: karst features like Ciudad Encantada and Calares, fluvial dynamics of the Tagus and Guadiana basins, and soil horizon formation.
3Understand hydrogeology of La Mancha aquifers (Aquifer 23 / Mancha Occidental), overexploitation risks, and mine geology like the historic Almadén cinnabar deposit.
4Focus on ecosystem energetics, trophic levels, biogeochemical cycles (carbon, nitrogen, phosphorus), and Mediterranean forest succession.
5Study Environmental Impact Assessment (EIA/EsIA) regulatory procedures, natural hazard risk formulas (Risk = Hazard x Exposure x Vulnerability), and climate mitigation.
