EarthViewer for iOS

What did Earth's continents and oceans look like 250 million years ago, or even 1 billion years ago? What do we know about the climate back when our planet formed? How has sea level changed since the melting of the last ice age and what does the future hold? EarthViewer is like a time machine for exploring Earth's deep history. Based on the latest scientific research, it lets you scroll through the last 4.5 billion years with your fingertips. Follow a favorite landmark, be it Greenland or New York City, as its position shifts through time, or watch a famous fossil like Tiktaalik make an incredible journey from its origin to its current location. Layer your view of shifting continents with data on atmospheric composition, temperature, biodiversity, day length, and solar luminosity, to get a more complete view of our dynamic planet. EarthViewer features include: Continental reconstructions and accompanying data dating back billions of years. Sea level maps for the last 21, 000 year and for 8, 000 years into the future. Global temperature maps for the last 100+ years. Ability to manipulate the globe and zoom to any location. Locations of modern cities tracked back over 500 million years. In-depth features on major geological and biological events in Earth history. Clickable details on geologic eons, eras, and periods. Automated play modes. Animations between globe and flat map projections. Extensive reference list. Suggestions for classroom use.
