2 pages. An activity to familiarize students with the geoheritage of volcanism in the Valles Caldera.
Great images of geoheritage sites can be found everywhere. But no one holding a camera on Earth can “back away” far enough to get the extraordinary perspective captured by NASA satellites. In celebration of Earth Science Week 2016, NASA's Earth Observatory has created a special collection of images and articles showcasing geoheritage sites in America’s National Parks.
How do archaeologists learn about climatic conditions and their effects on people in the past? In 1815, Mount Tambora in Indonesia erupted so violently that the sound of the eruption could be heard 1,600 miles away. Gases from the volcano shot into the stratosphere almost six miles above the Earth’s surface and lingered for years. Sulfur dioxide combined with water molecules to form sulfate particles that reflected sunlight away from Earth, gradually causing the planet’s surface to cool. The colder temperatures caused severe weather events worldwide.
