Access the official OCR A Level Geology H414/02 Scientific Literacy in Geology June 2025 mark scheme PDF. This examiner-approved OCR document contains the complete official answers, assessment criteria, level-of-response descriptors, graphical solutions, calculations, and examiner guidance used during the June 2025 OCR A Level Geology examination series.
The mark scheme covers a broad range of advanced geology topics including structural geology, folds and faulting, deformation and strain, palaeoclimatology, atmospheric CO2 change, supercontinents, ore geology, geochemistry, earthquake prediction, seismology, sea-floor spreading, trilobite palaeontology, Lagerstätten preservation, facies analysis, hydrogeology, engineering geology, and tectonic processes. It also includes official answers for practical investigations, graph interpretation, geological calculations, mapping exercises, data analysis, and extended-response scientific-literacy questions.
Students can use this OCR H414/02 mark scheme to understand exactly how examiners award marks for geological interpretation, palaeoenvironmental analysis, fossil evidence, engineering-geology reasoning, geophysical interpretation, scientific evaluation, and extended geological explanations. Detailed level-of-response descriptors also demonstrate how OCR assesses high-level scientific reasoning and evidence-based discussion in geology.
The mark scheme contains worked answers for calculations involving percentage mass change, magnification, geological graph plotting, and statistical correlation methods, alongside examiner guidance for fold geometry, seismic interpretation, hydrogeological failure, palaeoclimate evidence, and fossil-preservation analysis. This makes it highly valuable for revision, self-assessment, classroom teaching, mock examinations, and OCR examiner-style preparation.
Fully updated for the 2025/2026 academic year, the PDF is optimised for desktop, tablet, and mobile geology revision.
This document is designed for OCR A Level Geology students preparing for the 2026 examination series, including Year 13 Earth science students, tutors, independent learners, geology teachers, resit candidates, and home-school students studying advanced geological interpretation and scientific-literacy skills.
It is especially useful for students aiming to improve geological reasoning, data interpretation, palaeoenvironmental analysis, practical-investigation technique, engineering-geology understanding, and examiner-focused extended responses. Teachers and geology departments can also use the mark scheme for moderated marking, classroom assessment, mock-exam practice, and OCR assessment-standard training.
