Target concept: Lava landforms: The basaltic lava plateau of Iceland (flat, black rock) and the volcanic lava cone of Italy (hill-shaped, red rock)

Video generation prompt: The screen displays two columns: the left column shows the basaltic lava plateau of Iceland, and the right column shows the volcanic lava cone of Italy. The image highlights the color and shape of the rocks on both sides.

Evaluation guide:
(i) Target concept: Visual differentiation of two end-member volcanic landforms defined by magma composition, eruption style, and resulting morphology/color.
Minimum mechanism: Basaltic flood lavas produce extensive flat plains due to high fluidity and low gas content; basaltic scoria-cone eruptions (e.g., Etna-type) eject fragmented, gas-charged basaltic tephra that builds steep-sided cones, and oxidation of iron in that scoria during and after eruption yields the red coloration.
(ii)Storyline: Frame opens with full-screen side-by-side static view. Left region instantaneously establishes flat black rock field under neutral daylight; right region simultaneously establishes isolated red cone under identical lighting. Both regions remain fully visible, unmoving, and unoccluded for entire duration. No camera motion, no object animation, no temporal evolution, only sustained, simultaneous contrast. Viewpoint is frontal, eye-level, fixed, with horizon line centered and parallel to frame base in both columns.

Manual:
Experimental Procedure
1. Display two vertical columns occupying full screen width.
2. Left column: render a flat, barren expanse of black basaltic rock (Iceland lava plateau).
3. Right column: render a freestanding, hill-shaped cone of red volcanic rock (Italy lava cone).
Observation of Experimental Phenomena
- Left side shows uniformly flat, jet-black rock surface with no elevation change or vegetation.
- Right side shows a distinct conical hill with steep slopes and deep red coloration.
- A sharp vertical divider separates the two columns; black and red colors are mutually exclusive per side.
Summary of Experimental Principles
- Basaltic lava plateaus (e.g., Iceland) form from low-viscosity, iron-rich lava flows cooling into flat, black, fine-grained rock.
- Volcanic cones (e.g., Mt. Etna, Italy) form from explosive eruptions ejecting oxidized scoria and ash, building steep-sided, red-hued hills.

Prompt Grounding rubric:
level_1: No side-by-side column layout; either only one region is shown, or regions are stacked vertically, overlaid, or fragmented; no Iceland lava plateau and no Italy lava cone present.
level_2: Side-by-side layout exists but at least one location is mislabeled or replaced (e.g., left shows volcanic cone instead of plateau, or right shows basaltic terrain instead of cone); or one location is absent and replaced by unrelated terrain (e.g., desert, glacier, forest).
level_3: Side-by-side column layout is present with left column containing a flat black rock formation and right column containing a hill-shaped red rock formation; both formations are recognizably geological landforms, but shape or color fidelity is inconsistent with the specified types (e.g., left is flat but gray instead of black; right is conical but orange or brown instead of red).
level_4: Side-by-side column layout is present; left column shows a flat, black rock formation matching the description of a basaltic lava plateau; right column shows a hill-shaped, red rock formation matching the description of a volcanic lava cone; all object types, shapes, and colors are correct, but minor non-core flaws exist (e.g., subtle blending at column boundary, slight perspective tilt affecting flatness perception, or minor texture noise obscuring rock continuity).
level_5: Side-by-side column layout is precisely maintained for the entire video's duration; left column exclusively displays a flat, unbroken expanse of black rock with uniform basaltic texture and matte surface; right column exclusively displays an isolated, symmetrical hill-shaped red rock formation with sharp conical profile and consistent oxidized volcanic appearance; no visual intrusion, distortion, or ambiguity in spatial separation, labeling, or identity.

Scientific and Causal Correctness rubric:
level_1: No scientifically valid lava landform representation: neither plateau nor cone appears; colors and shapes contradict known geology (e.g., red flat plain, black cone, or fluid-like or vegetated surfaces).
level_2: At least one landform is present but violates core geoscience facts: e.g., left column shows a red flat plain (contradicts Iceland’s basaltic black), or right column shows a black cone (contradicts Italy’s oxidized red basaltic scoria/tephra); or shape is fundamentally wrong (e.g., right is flat, left is conical).
level_3: Both landforms are present with correct broad categories (flat vs. conical) and approximately correct dominant colors (black and red), but critical scientific attributes are missing or inverted: e.g., left plateau shows visible vegetation or soil cover (invalid for fresh basalt plateau), or right cone displays active lava flow or steam (not required per prompt and contradicts static landform focus); or color hue deviates to non-oxidized tones (e.g., rust-orange instead of deep brick-red for cone, charcoal-gray instead of jet-black for plateau).
level_4: Both landforms are visually accurate per geoscience knowledge: left is a barren, flat, black basaltic lava plateau with polygonal jointing or vesicular texture visible; right is a steep-sided, isolated, red-hued volcanic cone composed of scoria or oxidized tephra, with no vegetation, water, or anthropogenic features; all causal attributes (color from mineral composition, shape from eruption style) are implicitly supported, but one non-core scientific detail is inconsistent (e.g., unrealistic lighting casts blue shadow on red cone, or subtle atmospheric haze reduces red saturation without eliminating it).
level_5: Zero scientific deviation: left column shows only abiotic, unvegetated, flat black basalt with characteristic columnar jointing or smooth pahoehoe/ropy texture; right column shows only a discrete, symmetrical, red volcanic cone with granular scoria texture, no erosion gullies or weathering streaks inconsistent with young volcanic origin; color is spectrally faithful (jet-black vs. iron-oxide red), shape is geometrically distinct (plateau = horizontal plane; cone = radial symmetry + apex), and no extraneous phenomena (e.g., clouds, birds, shadows violating sun position) undermine causal integrity.

Spatiotemporal Consistency rubric:
level_1: Severe spatiotemporal rupture: the plateau and cone columns swap sides, one column disappears, or the two views merge into a single frame at any point; a hard jump-cut replaces one static view with a visibly different framing mid-video; the black basaltic plateau or the red volcanic cone warps or stretches enough to change its recognizable shape; or the shadow on one side visibly flips to the opposite side of the cone or plateau partway through the video.
level_2: Layout stays side-by-side but is visibly unstable: the vertical divider between the plateau and the cone drifts left or right over the course of the video; the cone or the plateau visibly grows, shrinks, or shifts position within its own column; or the overall brightness of one column changes noticeably partway through while the other column's brightness stays constant.
level_3: The plateau stays confined to the left column and the cone stays confined to the right column for the entire video, with no swapping, resizing, or drifting of either; the vertical divider holds a fixed position and width; the black rock's texture and the cone's silhouette do not ripple or warp across frames; the brightness and the shadow placement on the plateau and on the cone each look the same in the last frame as they did in the first.
level_4: All conditions for score 3 are met, and additionally: the divider line stays perfectly straight with no waviness or softening; the flat plateau's outline and the cone's sloped silhouette keep the exact same shape throughout, with no edges appearing or disappearing; both columns read as lit from the same fixed light source the entire time, with the cone's shadow and the plateau's shadow never appearing to shift direction relative to one another.
level_5: All conditions for score 4 are met, and additionally: comparing the first frame to the last frame, the plateau's rock outline, the cone's silhouette, the divider's position, and the shadow placement in both columns are indistinguishable from one another; nothing in either column appears to move, flicker, or change size at any point across the full video.
