Igneous Rocks Concept Map Explained

An igneous rocks concept map shows how rocks form when molten material cools and solidifies. The main split is between magma that cools slowly underground, making intrusive rocks such as granite, and lava that cools quickly at the surface, making extrusive rocks such as basalt. Texture links these groups, since cooling rate sets crystal size.

  • Magma and lava: the molten source, underground or at the surface
  • Intrusive rocks: slow cooling, coarse grains, for example granite and gabbro
  • Extrusive rocks: fast cooling, fine or glassy grains, for example basalt and obsidian
  • Textures: phaneritic, aphanitic, porphyritic and glassy, linked to cooling rate
  • Mineral composition: felsic and mafic rocks, based on silica content

Use the map to revise the difference between intrusive and extrusive rocks before an exam. You can build a personalized igneous rock map from your own notes with CogniGuide.

Igneous Rocks Questions Answered

Common questions about igneous rocks and making your own map.

What is the difference between intrusive and extrusive igneous rocks?

Intrusive rocks form when magma cools slowly beneath the surface, giving large visible crystals. Extrusive rocks form when lava cools quickly at the surface, giving fine grains or glassy textures.

What are the most common igneous rocks?

Granite is a common intrusive rock and basalt is a common extrusive rock. Basalt makes up much of the oceanic crust.

Which files can I use to make an igneous rock map?

You can upload PDF, Word, PowerPoint, text, Markdown or image files, or simply type a topic. The AI builds the map from that content.

Is the igneous rock map generator free to use?

There is a free plan with 5 creations a week and no payment needed. Paid plans raise the limits. You can also turn your map into a quiz.
