Create a polished vertical 3:4 educational geology infographic titled “THE ROCK CYCLE”, designed as a clear classroom reference explaining how igneous, sedimentary, and metamorphic rocks transform through continuous geological processes.
CANVAS AND LAYOUT
Use a portrait poster with a warm pale-stone background #EFE8DA and a large centered title at the top. Arrange the main rock types and process illustrations in a circular flow occupying most of the poster:
- igneous rock near the upper center;
- sedimentary rock on the middle right;
- metamorphic rock near the lower center;
- magma and volcanic activity on the middle left;
- weathering and erosion in the upper-right area;
- melting in the lower-left area.
Connect all stages with thick curved directional arrows. Keep every arrowhead clear, every label readable, and the overall cycle easy to follow clockwise while also showing valid alternate pathways.
TITLE
Render:
“THE ROCK CYCLE”
Use a bold clean sans serif in deep geological red #9E241D, centered at the top with generous spacing. No subtitle.
MAIN STAGES
IGNEOUS ROCK
Heading:
“Igneous Rock”
Supporting copy:
“Forms when magma or lava cools and solidifies.”
Illustrate one dark gray volcanic rock with irregular angular geometry, subtle crystalline texture, and softly highlighted edges.
COOLING AND SOLIDIFICATION
Process label:
“Cooling and Solidification”
Supporting copy:
“Molten rock loses heat and becomes solid rock.”
Place this process between magma and igneous rock with one strong upward-curving arrow.
WEATHERING AND EROSION
Process label:
“Weathering and Erosion”
Supporting copy:
“Rocks are broken into smaller sediments and transported.”
Illustrate green hills with a winding blue river, exposed soil, and small loose rock particles. Connect igneous, sedimentary, and metamorphic rocks toward this process where space allows without clutter.
SEDIMENTS
Label:
“Sediments”
Illustrate loose grains, pebbles, sand, and mud collecting in horizontal layers near the weathering scene.
COMPACTION AND CEMENTATION
Process label:
“Compaction and Cementation”
Supporting copy:
“Layers of sediment are pressed and bound together.”
Use a downward arrow from sediments to sedimentary rock.
SEDIMENTARY ROCK
Heading:
“Sedimentary Rock”
Supporting copy:
“Forms from compacted and cemented layers of sediment.”
Illustrate a rectangular rock block with clearly visible horizontal layers in tan, cream, rust, and gray.
HEAT AND PRESSURE
Process label:
“Heat and Pressure”
Supporting copy:
“Burial changes existing rock without melting it.”
Use strong curved arrows from igneous and sedimentary rock toward metamorphic rock.
METAMORPHIC ROCK
Heading:
“Metamorphic Rock”
Supporting copy:
“Forms when existing rock changes under heat and pressure.”
Illustrate a gray rock with wavy black-and-white mineral bands, folded crystalline texture, and a compact irregular shape.
MELTING
Process label:
“Melting”
Supporting copy:
“Extreme heat turns rock into molten material.”
Connect metamorphic, sedimentary, and igneous rock toward magma with curved arrows where visually clear.
MAGMA
Heading:
“Magma”
Supporting copy:
“Molten rock beneath Earth’s surface.”
Illustrate glowing orange-red molten rock beneath a small erupting volcano, with lava, dark slopes, smoke, and controlled warm highlights.
ARROW LOGIC
Show these essential transformations clearly:
- Magma → Cooling and Solidification → Igneous Rock
- Igneous Rock → Weathering and Erosion → Sediments
- Sediments → Compaction and Cementation → Sedimentary Rock
- Sedimentary Rock → Heat and Pressure → Metamorphic Rock
- Igneous Rock → Heat and Pressure → Metamorphic Rock
- Metamorphic Rock → Melting → Magma
- Sedimentary Rock → Melting → Magma
- Igneous Rock → Melting → Magma
Optional secondary arrows may indicate that any exposed rock can weather into sediments, but avoid visual congestion.
TYPOGRAPHY
Use a bold dark charcoal sans serif for rock names and process headings. Use a smaller clean sans serif for supporting explanations. Keep all text horizontal, high contrast, and comfortably separated from illustrations and arrowheads. Render all listed text exactly once.
ART DIRECTION
Use friendly semi-realistic educational illustration with lightly painted textures, crisp outlines, natural geological color variation, and a subtle textbook-poster finish. Keep rocks scientifically recognizable but simplified enough for young learners.
COLOR ROLES
Use pale stone #EFE8DA for the background, geological red #9E241D for the title, charcoal #252321 for primary labels and arrows, volcanic gray #4C4945 for igneous rock, layered tan #C8A66A and rust #A85F3D for sedimentary rock, mineral gray #777B7D and off-white #E6E3DA for metamorphic bands, magma orange #F36B16, lava yellow #FFD04A, river blue #4EA5D9, vegetation green #6C9A42, and soil brown #7A563A.
COMPOSITION RULES
Maintain a clear circular flow with the three main rock types forming a broad triangle. Keep process labels close to their corresponding arrows. Use consistent arrow thickness and one arrowhead per direction. Leave enough open space around the center so paths do not merge into an unreadable knot.
PRESERVE
Preserve the cyclical educational structure, the three principal rock types, magma, weathering and erosion, sediments, compaction and cementation, heat and pressure, melting, directional arrows, and the warm classroom-poster character.
CONSTRAINTS
Keep the geological relationships correct. Do not imply that sedimentation alone creates sedimentary rock; include compaction and cementation. Do not imply that metamorphic rock melts during metamorphism. Avoid backward arrowheads, crossing labels, duplicate stages, missing rock types, incorrect process names, unreadable microtext, logos, brand marks, signatures, QR codes, or watermarks.
OUTPUT
Produce a clean, bright, high-resolution, print-ready geology infographic with crisp edges, balanced spacing, accurate process relationships, readable text zones, and strong classroom legibility.
