The rock cycle: how a mountain becomes marble
Process map by Brian. 11 steps, 1 layer. Tags: science, earth.
- Magma and lava: Magma cools: slowly underground, fast at the surface
- The rock: Igneous rock forms (granite, basalt)
- Heat, pressure and weather: Weathering and erosion break it down
- The rock: Grains wash into rivers and seas
- Heat, pressure and weather: Buried and squeezed for millions of years
- The rock: Sedimentary rock (sandstone, limestone)
- Heat, pressure and weather: Buried deeper: heat and pressure rise
- Heat, pressure and weather: Hot enough to melt?
- Magma and lava: The rock melts into magma
- The rock: Heat and pressure rewrite the minerals: marble, slate
- Heat, pressure and weather: Pushed up by mountain-building, or buried deeper?
