Rock Cycle Wheel

playable

rock_cycle_wheel · earth_space · sequencer.cycle

Concept: Rock cycle

Player does: Rotate processes so each rock type becomes the next

Breaks: Rocks only change in one direction

The rock cycle has no fixed starting point; igneous, sedimentary, and metamorphic rock can each transform into any other type.

Strata X-Ray

playable

strata_xray · earth_space · sequencer.rank

Concept: Relative dating

Player does: X-ray the cliff; order layers oldest to youngest

Breaks: Layer order says nothing about age

The law of superposition means undisturbed rock layers get younger from bottom to top.

Plate Boundary Sorter

playable

plate_boundary_sorter · earth_space · sorter.bins

Concept: Plate boundaries

Player does: Sort features to convergent, divergent, or transform boundaries

Breaks: Earthquakes only happen at convergent boundaries

Earthquakes occur at all three boundary types, including the sliding motion of transform boundaries.

Earthquake Triangulation

playable

earthquake_triangulation · earth_space · mapper.plane

Concept: Locating epicenters

Player does: Draw three distance circles; mark where they meet

Breaks: One station can locate the epicenter

A single seismic station gives only a distance, so at least three stations are needed to triangulate the epicenter.

Water Cycle Wheel

playable

water_cycle_wheel · earth_space · sequencer.cycle

Concept: Water cycle

Player does: Restart the cycle by triggering stages in order

Breaks: Clouds are water vapor

Clouds are condensed liquid droplets or ice, while water vapor itself is invisible gas.

Moon Phase Orbit

playable

moon_phase_orbit · earth_space · mapper.plane

Concept: Moon phases

Player does: Place the Moon in its orbit to show the requested phase

Breaks: Phases are Earth's shadow

Moon phases come from the changing angle at which we see the Moon's sunlit half, not from Earth's shadow.

Seasons Tilt

playable

seasons_tilt · earth_space · truth_finder.mimic

Concept: Seasons

Player does: Expose the claim that summer is when Earth is closest to the Sun

Breaks: Seasons come from distance to the Sun

Seasons come from Earth's axial tilt changing sunlight angle and day length, not from distance to the Sun.

Greenhouse Dial

playable

greenhouse_dial · earth_space · simulator.intervene

Concept: Greenhouse effect

Player does: Adjust emissions to keep temperature in the band

Breaks: The greenhouse effect is the ozone hole

The greenhouse effect traps heat via gases like CO2, which is a separate process from ozone depletion.

Star Life

playable

star_life · earth_space · sequencer.linear

Concept: Stellar evolution

Player does: Route the star through its life stages by mass

Breaks: All stars end as black holes

A star's mass decides its fate: only very massive stars can collapse into a black hole; smaller stars end as white dwarfs or neutron stars.

Weather Fronts

playable

weather_fronts · earth_space · truth_finder.predict_reveal

Concept: Air masses & fronts

Player does: Predict the weather as the cold front arrives

Breaks: Warm air slides under cold air at a front

Warm air is less dense, so at a front it rises up and over the advancing cold air, not the other way around.
