Geology Spider Diagram: Topics and Structure
A geology spider diagram places one central idea, such as the rock cycle or plate tectonics, at the centre and branches out to related concepts. The main branches usually cover the three rock types, the minerals that form them, and the processes that change them over time, including weathering, erosion, heat and pressure. Seeing these links at once helps you compare rock formation and recall how each process connects.
- Igneous rock: formed when magma or lava cools and solidifies
- Sedimentary rock: built from layers of compacted sediment and fossils
- Metamorphic rock: changed by heat and pressure without melting
- Minerals: identified by hardness, lustre, streak and cleavage
- Processes: weathering, erosion, deposition, burial and uplift
Use the diagram to revise before an exam or to plan an essay on the rock cycle. When you are ready, CogniGuide can build a personalised geology spider diagram from your own notes.

Geology Spider Diagram Questions
Answers on the topic and on making your own map.
What are the three main rock types in geology?
The three main rock types are igneous, sedimentary and metamorphic. Igneous rock forms from cooled magma or lava, sedimentary rock from compacted sediment, and metamorphic rock from existing rock changed by heat and pressure.
What is the rock cycle?
The rock cycle describes how rocks change from one type to another over time. Weathering, erosion, melting, cooling and metamorphism move material between the three rock types.
Which files can I use to make a geology diagram?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of notes. You can also type a topic instead of uploading a file.
Can I turn my geology spider diagram into a quiz?
Yes. Once the map is created, you can turn it into a quiz to test yourself. The same notes can also become flashcards. There is a free plan with 5 creations a week.
