What did Earth look like 250 million years ago? Or 1 billion years ago? Or 4.5 billion years ago? What was the climate like in the deep past?
Find the answers with EarthViewer, an interactive tool for exploring the science of Earth's deep history. From molten mass to snowball earth, EarthViewer lets you see continents grow and shift as you scroll through billions of years. Additional layers let you and your students explore changes in atmospheric composition, temperature, biodiversity, day length, and solar luminosity over deep time.
"EarthViewer was conceived as a high school-level resource, but its engaging interface and well-executed information screens make it accessible to students as young as sixth grade as they develop understanding in the disciplinary core ideas of the Next Generation Science Standards.[...] The app provides additional, unique opportunities to address Common Core State Standards (CCSS), ELA, for grades 6-12, especially in the Integration of Knowledge and Ideas and the Research to Built and Present Knowledge areas. [...] an excellent app that can be at the center of inquiry-based learning in any classroom."
