Earth's Pulse: Volcanoes, Earthquakes, Rocks

Ever wondered why some mountains erupt while others crumble? Earth is a living planet, and its surface is constantly reshaped by powerful forces. This quiz tests your knowledge of three core Earth science topics: volcanoes, earthquakes, and rocks. You'll explore how magma rises to form volcanic cones, how tectonic plates grind and slip causing seismic waves, and how rocks transform through the rock cycle. Did you know that the Ring of Fire accounts for about 75% of the world's active volcanoes? Or that the Richter scale, used to measure earthquake magnitude, is logarithmic—each whole number step means 10 times more ground motion? Rocks are time capsules: granite from the continental crust can be billions of years old, while lava from a recent eruption solidifies in hours. In this 8-question challenge, you'll answer questions on famous volcanic types, earthquake measurement, and rock classification. Whether you're a budding geologist or just curious about the ground beneath your feet, you'll learn something new. At the end, you'll get a result reflecting your score: from 'Trembling Novice' to 'Eruption Expert'. So put on your hard hat and let's dig into the dynamic Earth!
