From the thin air of Mount Everest to the intense pressure of the Challenger Deep, Earth is full of amazing extremes! Record-setting extremes are always being updated. Scientists and explorers discover new materials and refine their measuring methods, upsetting our ideas of "biggest" or "oldest." Weather patterns set new records, identifying new locations for "wettest" or "driest." The dynamic activity of Earth itself -- our rifting and shifting tectonic plates -- redefines "highest" and "lowest." What are Earth's extremes today? Follow this GeoStory to learn about Earth's extremes, from highest and lowest to hottest and coldest!
