OCR A Level Geology Paper 3 2025 Question Paper

Access the official OCR A Level Geology H414/03 Practical Skills in Geology June 2025 question paper PDF. This examiner-produced OCR paper contains the exact practical-investigation, geological interpretation, mapping, sedimentology, petroleum geology, and fieldwork questions sat by candidates during the June 2025 OCR A Level Geology examination series.

The paper assesses a wide range of practical geology topics including carbonate-rock classification using the Dunham scheme, metamorphic textures, igneous-rock comparison, flume-tank ripple experiments, sedimentary structures, graded bedding, petroleum geology, oil and gas traps, porosity and permeability, geothermal gradients, geological mapping, dip-and-strike measurement, overturned strata, and field-based geological interpretation.

Students are tested through geological calculations, graph plotting, fieldwork-style analysis, thin-section interpretation, sedimentological experiments, petroleum-system analysis, geological cross-sections, and practical mapping exercises. The paper also includes extended-response tasks on comparing igneous-rock composition and texture, and using a compass clinometer to measure dip and strike.

Major question themes include carbonate depositional environments, metamorphic-grade interpretation, wave-ripple formation in flume tanks, Jurassic ripple-mark palaeoenvironments, graded bedding experiments, North Sea oil and gas structural traps, sedimentary-rock porosity analysis, geothermal gradients within oil windows, and geological mapping using the Carrick map extract.

This OCR H414/03 June 2025 question paper is ideal for timed mock examinations, OCR examiner-style practical-skills preparation, fieldwork training, geological 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 A Level Geology students preparing for the 2026 examination series, including Year 13 Earth science students, geology teachers, tutors, independent learners, resit candidates, and home-school students studying practical geology and fieldwork interpretation.

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