OCR As Geology Paper 1 2025 Question Paper

Access the official OCR AS Level Geology H014/01 Geology June 2025 question paper PDF. This examiner-produced OCR paper contains the exact multiple-choice, practical, mapping, sedimentology, mineralogy, palaeontology, structural geology, and extended-response questions sat by candidates during the June 2025 OCR AS Geology examination series.

The paper assesses a broad range of AS Level geology topics including Goldschmidt classification, Earth structure, igneous and sedimentary rocks, Dunham limestone classification, weathering, subduction zones, earthquake foci, geological fieldwork methods, radioactive dating, mineral properties, silicate structures, igneous intrusions, sediment grain-size analysis, metamorphism, geological mapping, stress-strain behaviour, stratigraphy, facies interpretation, and biostratigraphic correlation.

Students are tested through geological calculations, graph plotting, cumulative-frequency analysis, geological cross-sections, mineral identification, field-sketch interpretation, sedimentological investigation, metamorphic interpretation, and palaeoenvironmental analysis. The paper also includes extended-response tasks on laboratory density determination, river-versus-beach sediment comparison, and geological interpretation of facies and fossils.

Major question themes include Benioff zones beneath Japan, sediment sieving experiments, grain-size distributions, geothermal pressure gradients, sill intrusions, stress-strain relationships in sandstone, unconformities and faults, regional metamorphism, Jurassic ammonite zone fossils, and marine facies correlation across sedimentary basins.

This OCR H014/01 June 2025 question paper is ideal for timed mock examinations, OCR examiner-style preparation, geology practical-skills development, mapping practice, and independent Earth-science revision. Fully updated for the 2025/2026 academic year, the PDF is optimised for desktop, tablet, and mobile geology study.

This document is designed for OCR AS Level Geology students preparing for the 2026 examination series, including Year 12 Earth science students, geology teachers, tutors, independent learners, resit candidates, and home-school students studying introductory geological processes and Earth systems.

It is especially valuable for students aiming to improve practical-investigation techniques, geological calculations, sedimentological interpretation, mapping skills, mineral identification, and examiner-focused analytical responses. Teachers and geology departments can also use the paper for classroom assessment, geology practical workshops, field-skills training, and OCR-standard mock examinations.
