Geology

Explain Earth's rocks, processes, and history from field trips to research.

Security Scan

This is an instruction-only teaching skill about geology with no installs, no requested credentials, and no suspicious instructions — it appears to do what it says.

Purpose & Capability

Name/description match the content of SKILL.md. The skill is pedagogical (beginners → researchers → teachers) and does not request unrelated capabilities or secrets.

Instruction Scope

Runtime instructions are purely instructional guidance for explaining geological concepts and field practice. They do not direct the agent to read files, access environment variables, or send data to external endpoints.

Install Mechanism

No install spec and no code files are present. Nothing will be written to disk or fetched during installation.

Credentials

The skill declares no required environment variables, credentials, or config paths — consistent with its teaching purpose.

Persistence & Privilege

always is false and the skill is user-invocable. It does not request permanent presence or elevated privileges.

Assessment

This skill is instruction-only and internally consistent with its stated teaching purpose. It does not request credentials or install software. If you install it, be aware: (1) the content is educational — verify technical details against primary literature for research-critical use, and (2) the agent may use the skill autonomously (normal for skills), but this skill itself does not grant extra system access. If you need the agent to use local field data (files, GPS) ensure you only provide those explicitly and understand what you are sharing.

Detect Level, Adapt Everything

• Context reveals level: terminology used, scale of questions, tools mentioned
• When unclear, start with observable features and adjust based on response
• Never condescend to experts or overwhelm beginners

For Beginners: Rocks Tell Stories

• Start with what they can touch — pick up a rock, describe what you see
• Three rock families — igneous (fire), sedimentary (layers), metamorphic (changed)
• Fossils as time capsules — "This shell lived when dinosaurs walked"
• Deep time through comparison — "If Earth's history were a day, humans arrive at 11:59 PM"
• Plate tectonics as puzzle pieces — continents fit together, they moved
• Volcanoes and earthquakes connected — same engine, different expressions
• Connect to landscape — "Why is this mountain here? Why is this valley flat?"

For Students: Process and Evidence

• Rock cycle as system — trace pathways, identify what drives each transformation
• Mineral identification systematic — hardness, luster, cleavage, streak, crystal form
• Stratigraphy principles — superposition, original horizontality, cross-cutting relationships
• Plate boundaries explain patterns — divergent, convergent, transform produce different features
• Deep time requires calibration — radiometric dating, index fossils, correlation
• Read landscapes — drainage patterns, fault scarps, glacial features tell history
• Field notebooks matter — location, orientation, scale in every sketch

For Researchers: Precision and Context

• Specify scale explicitly — hand sample, outcrop, regional, global behave differently
• Methods have assumptions — isotope systems, geophysical models, each has limitations
• Uncertainty is inherent — age ranges, paleoclimate proxies, reconstruction confidence
• Literature is regional — what's established for Alps may not apply to Andes
• Distinguish observation from interpretation — "We see X" vs "This suggests Y"
• Earth systems interact — can't isolate tectonics from climate from life
• Economic and hazard relevance — resources, risk assessment, land use implications

For Teachers: Common Misconceptions

• Rocks aren't eternal — they form, change, and get destroyed
• Continents don't "float" like boats — plates include oceanic and continental crust
• Fossils don't require dinosaurs — most are shells, plants, microorganisms
• Volcanoes aren't random — they cluster at plate boundaries and hotspots
• Deep time is genuinely hard — return to it repeatedly with different analogies
• Field experience irreplaceable — photos help, but handling rocks teaches texture
• Connect to local geology — every location has a story, use what's nearby

Always

• Specify location and context — geology is place-specific
• Connect present processes to past evidence — uniformitarianism with caveats
• Scale matters — always clarify temporal and spatial scale being discussed
