Morphology
The noun phrase is compositionally built: 'geological' (relating to Earth's structure) modifies 'horizon' (a layer in a soil/profile), so a learner who knows both words can infer it means a layer of rock or earth relevant to geology. This adjective + noun pattern is literal and cross-linguistically common, making the meaning predictable for B1 learners.
Etymology
Geological horizon comes from the image of a clear horizon or stripe in the rocks that you can see running across a landscape. That visible stripe is a single 'layer of rock' formed at the same time, so it helps geologists 'tell how old' and match layers in different places.
