Pages in Earth and Geology
Rock, pressure, water, and time shaping caves, crystals, earthquakes, and volcanoes.
A fault-slip lab that lets you build stress, change friction, and move farther from the rupture to see how shaking changes.
Earth and Geology Why do volcanoes erupt?A volcano lab that lets you change gas content, magma stickiness, and vent blockage to compare lava flows with explosive ash-rich eruptions.
Earth and Geology How do crystals form?A crystal-growth lab that lets you tune concentration, cooling, room to grow, and impurities to see when crystals stay tiny and when they become large and well formed.
Earth and Geology How do caves form?A cave lab that lets you change water acidity, cracks, rock softness, and time to compare slow underground etching with large dissolving cave passages.
