Canary Islands PAU Geology & Env Sci study guide
Canary Islands PAU Geology & Env Sci · Work through your exam, one topic at a time.
The PAU in Geología y Ciencias Ambientales is the university-access examination taken in the Canary Islands by students who want to use this subject in their admission score, typically for degrees in geology, environmental sciences, biology, geography, engineering or teaching. It is a written test built around the two-year Geology and Environmental Sciences curriculum: internal and external geodynamics, minerals and rocks, historical geology, geological hazards and maps, then the atmosphere and climate, the hydrosphere and coasts, island ecosystems and soils, and finally environmental impact, pollution and sustainability. The Canary Islands PAU Geology & Env Sci study guide has 9 sections and about 4,225 words.
01Internal Geodynamics: Earth's Structure, Plate Tectonics and Magmatic–Metamorphic Processes
Domain 1 tests Earth's internal layering, the mechanics of plate tectonics, and the magmatic and metamorphic processes that built the Canarian archipelago. The PAU rewards candidates who move in one chain: from seismic evidence to a layer model, from a plate setting to a magma type, from a mineral assemblage to a metamorphic grade.
502 words, about 3 min02External Geodynamics: Weathering, Erosion, Transport, Sedimentation and Sedimentary Environments
Domain 2 examines the exogenous cycle: how rock is broken down, moved and deposited, and how the resulting sediments record the environment. Island settings make this examinable through basalt weathering, barranco flash-flood transport, aeolian dunes and volcaniclastic marine deposits.
443 words, about 2 min03Historical Geology, Stratigraphy, Fossils and Geological Time
Domain 3 covers how geologists order events and date them, and how fossils and strata record Earth history. In the PAU it typically appears as a stratigraphic column or cross-section to interpret, plus dating method questions - including the age of the Canarian islands.
451 words, about 2 min04Minerals, Rocks and Their Identification; Petrogenetic Processes
Domain 4 tests mineral properties, rock classification and the petrogenetic paths that connect them. Expect to identify a sample from description or to place a rock in the cycle using texture and mineralogy - a common Canarian exam item, since the islands supply basalt, trachyte, phonolite, ignimbrite, tuff and calcrete in one small area.
439 words, about 2 min05Geological Hazards, Risks and Natural Resources; Geological Maps and Cross-Sections
Domain 5 combines hazard science with map interpretation. The exam expects a precise definition chain - hazard, exposure, vulnerability, risk - applied to Canarian volcanoes, seismicity and landslides, plus the ability to read a geological map and construct or correct a cross-section.
509 words, about 3 min06The Atmosphere and Climate: Composition, Dynamics, Climate Change and the Canarian Context
Domain 6 tests atmospheric composition and structure, the greenhouse effect, general circulation, and climate change evidence - then applies it to the Canarian climate, which is dominated by the trade winds and the subtropical anticyclone. Exam items often ask you to explain why the islands are mild, humid on the north and arid in the south.
466 words, about 2 min07The Hydrosphere and Oceanography: Water Cycle, Ocean Dynamics and Coastal Processes
Domain 7 covers the water cycle, ocean circulation and the coastal processes shaping island shorelines. In an archipelago with limited aquifers and strong wave energy, the exam expects quantitative-style reasoning about residence times, upwelling, longshore drift and the balance between recharge and extraction.
479 words, about 2 min08Biosphere, Soils and Ecosystems: Biodiversity and Conservation in Island Environments
Domain 8 links soil formation to vegetation zones and island biogeography, then to conservation. The exam's favourite angle is why the Canaries concentrate so much endemism, what threatens it, and how protected areas and legislation respond.
481 words, about 2 min09Environmental Impact, Pollution, Waste Management and Sustainable Development
Domain 9 tests impact assessment, pollutant behaviour and waste hierarchy, applied to a densely populated, tourism-driven archipelago with limited land, scarce water and fragile coasts. Expect to evaluate an activity (a road, a desalination plant, a wind farm, a landfill) and argue a defensible position using indicators.
