Meaning and Definition
The process of being shaped or moulded by flow.
In geology and materials science, the phenomenon where a material, often a heated rock or sediment, flows and deforms plastically under pressure, behaving like a viscous fluid.

FAQ
Frequently Asked Questions
No. Rheomorphism involves flow and deformation while the material is in a solid-state or partially molten (ductile) condition. Complete melting is a different process.
No. It is specifically used for materials that are normally considered solid (like rocks) but exhibit fluid-like flow under special conditions. Lava flow is simply 'flow' or 'fluidity'.
Only if you are studying advanced geology or materials science. For general English, it is an extremely rare and highly specialised term.
Rheology is the broader science of the flow and deformation of matter. Rheomorphism is a specific geological process or phenomenon studied within rheology.
The process of being shaped or moulded by flow.
Rheomorphism is usually highly specialised technical in register.
Rheomorphism: in British English it is pronounced /ˌriːəʊˈmɔːfɪz(ə)m/, and in American English it is pronounced /ˌrioʊˈmɔːrfɪzəm/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'rheo-' (like rheostat, controlling flow) + 'morph' (shape). It's the shaping of something by flow.
Conceptual Metaphor
ROCK IS A VISCOUS FLUID (Under specific high-pressure, high-temperature conditions).
