Magma Formation Concept Map Explained
A magma formation concept map shows how magma forms when rock melts beneath Earth's surface. Magma is molten rock, and it forms mainly in two settings: the mantle, where decompression melting occurs at mid-ocean ridges and hot spots, and the crust, where flux melting from water and heat transfer from intrusions cause partial melting. Once formed, magma rises because it is less dense than surrounding rock, then cools into different igneous rocks.
- Melting processes: decompression, flux and heat-driven melting
- Magma composition: basaltic, andesitic and rhyolitic types
- Ascent: buoyancy, pressure and fracture pathways
- Storage: magma chambers in the crust
- Cooling: intrusive versus extrusive crystallization
Use the map to review each stage in order, then test yourself on causes and outcomes. You can build a personalized version from your own notes with CogniGuide.

Magma Formation Questions
Common questions about magma and how to map it.
What is the difference between magma and lava?
Magma is molten rock beneath the surface. Once it erupts onto the surface, it is called lava. The composition is largely the same, but lava loses dissolved gases and cools rapidly.
Where does most magma form?
Most magma forms in the upper mantle and lower crust. Decompression at mid-ocean ridges and water-driven melting at subduction zones are the two most important settings.
Can CogniGuide make a magma map from my lecture notes?
Yes. Upload a PDF, Word or PowerPoint file, a text or Markdown file, or an image of your notes, or type the topic. The AI builds an expandable mind map from it.
Is the magma map feature free to try?
Yes. The free plan allows 5 creations a week with no payment needed. Paid plans raise those limits.
