Planet Crunch: The Ultimate Rock-Smart Geology Showdown
This quiz spins your brain like a tectonic plate on fast-forward. From the fire of volcanoes to the quiet creep of continents, geology tracks the wild history of our restless planet. Expect questions that jump from microscopic minerals to mountains tall enough to punch the sky. You will cross ancient seas, walk across vanished supercontinents, and time‑travel through mass extinctions, all through the lens of rock science. Along the way, you will meet shape‑shifting rocks, sneaky groundwater, and earthquakes that rewrite landscapes in seconds. Whether you are a casual rock spotter or a hardcore plate‑tectonics fan, this challenge is built to surprise you, stump you, and maybe even change how you look at the ground under your feet. Sharpen your curiosity, steady your inner seismograph, and see how rock-solid your science‑geology knowledge really is.
