The lithosphere and plate tectonics — IGCSE Marine Science (0697) questions by topic
Nine questions here work from labelled diagrams of Earth's layers or 3D block diagrams of underwater plate boundaries, asking you to state, name or explain what a labelled feature represents, worth between 10 and 15 marks.
State, explain, describe, name and complete require different things: name wants a precise term, explain wants a mechanism, not just a description. Drawn from 2024 and 2025 papers across these 9 questions, this page's instant marking is well matched to diagram-reading topics, where checking whether you named the correct layer or boundary type against the mark scheme catches labelling slips at once, before they recur across a whole paper.
