HHMI's BioInteractive

about the app

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, a new 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.
