Geological Landmarks Quiz – Wonders Written in Stone

Earth's most spectacular landmarks reveal powerful geological processes. Rivers carved the Grand Canyon, lava cooled into the Giant's Causeway columns and wind and water shaped sandstone into the Wave and Uluru.

Many landmarks show erosion acting on different rocks. Soft volcanic tuff in Cappadocia formed fairy chimneys, limestone in Ha Long Bay became islands and quartz sandstone in Zhangjiajie rose into tall pillars.

These sites are often protected as national parks and UNESCO sites. They attract millions of visitors and teach us about Earth's deep history, from ancient seas to meteor impacts.
