Separate a mineral, rock and process
See this course’s project requirements
An Earth-system evidence board linking a rock cycle, plate-boundary model, earthquake/volcano distribution and a cautious geological explanation.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Separate mineral, rock and geological process cards.
- Draw a branching rock-cycle route with process labels.
- Compare divergent, convergent and transform motion.
- Interpret supplied earthquake/volcano patterns with an exception.
- Distinguish hazard probability and post-onset warning from exact prediction.
- Build a bounded landform evidence board and complete changed cases.
Review and revise
Use these criteria to check your work and choose what to improve.
- Method: applies the course-specific rules to the supplied cases with visible intermediate work.
- Accuracy: results agree with the stated facts, units, boundaries and independent checks.
- Reasoning: explains why the result follows and identifies a limitation or unresolved question.
- Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life
Supplied cards: Q—quartz mineral with a stated crystalline structure and composition; G—granite rock containing quartz, feldspar and mica; E—river water transports loose sediment downstream. Descriptions supply the classification evidence.
A mineral is a naturally occurring inorganic solid with an ordered structure and characteristic composition. A rock is an aggregate of minerals or other geological material. A process such as erosion changes or moves material; it is not itself a substance. Identification needs more than a color, and this course uses supplied cards rather than handling unknown samples.
Separate a mineral, rock and process — worked practice
A mineral is a naturally occurring inorganic solid with an ordered structure and characteristic composition. A rock is an aggregate of minerals or other geological material. A process such as erosion changes or moves material; it is not itself a substance. Identification needs more than a color, and this course uses supplied cards rather than handling unknown samples.

1. 1. Q
Use the stated composition and ordered structure.
You should see: Q is the supplied mineral example.
2. 2. G
Use the presence of multiple mineral constituents.
You should see: G is the supplied rock example.
3. 3. E
Distinguish movement from material identity.
You should see: E describes erosion/transport, a process.
4. 4. Limit
Explain why color alone would not identify an unknown sample.
You should see: Several materials can share a color; the cards contain additional evidence.
What to finish
A mineral/rock/process table with one identification limitation.
Watch for this
A single visible feature is not enough for a reliable material identification. The lesson’s classification relies on supplied structural and composition evidence.
How can I tell I understand it?
Classify a changed aggregate without turning a process into a substance.
