Fast and Slow Earth Changes

Some Earth processes reshape the surface in moments, like a landslide or a volcanic eruption, while others, like the slow collision of continents that builds a mountain range, take millions of years and are only noticeable when their effects are measured or compared over long stretches of time. Earth's surface is constantly changing at both of these very different scales at once.
