Description

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?

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
• World temperature map 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
• Extensive reference list
• Suggestions for classroom use
• Tutorial videos

The Howard Hughes Medical Institute (HHMI) is a non-profit medical research organization that ranks as one of the nation’s largest philanthropies. HHMI’s BioInteractive initiative opens a window on cutting-edge science through interactive web features, short films, virtual labs, and scientific animations. Since teachers play a pivotal role in launching the careers of future scientists and in helping the public understand the beauty and import of science, the BioInteractive team partners with the teaching community to create and distribute media that is engaging and relevant to the science curriculum.

Great Idea Needing Development

I'm giving this five stars because it's such a great idea. The app includes many details of major epochs of Earth's history that are not available in other apps. In fact, I know of no other geologic history app that exceed this app's quality.

The downside is that when scrolling through the timeline, the phases of Earth's history appear as single images. Transition between the images plays as a slideshow. In future versions, I recommend a full morph between images so Earth's history plays as a smooth video instead of as single images fading into each other.

Despite this downside, I'm giving this app five stars because it's a fantastic idea. Since there are many image editing tools that can easily fix the fade vs. morph issue, I'm certain that it will not occur in future versions.

Great app for seeing the Earth's evolution but needs ice ages

As a geologist, this is the nicest app I have found to show the incredible changes our earth has gone through. Great for also seeing the changes in temperature, CO2 and life diversity in chart form as you slide though the ages. I use it primarily for non-geologist, but when working a new project will also pop it open to get an overview of an area over time.

The app has a heartbreaking flaw in not having the Pleistocene ice ages in it. These are the most dramatic geologic and climatic changes that most people will see and understand, often because they are actually standing where thousands of feet of ice were just a few thousand years go. There are many sources for the advance and retreat lines as well as temperature that could be built in.

Great, but one flaw

Earth Viewer
This is a great app!!! One thing that I really liked about this app is that it is super easy to understand. The image of the earth is really big and you can scroll around on it to see the whole thing. I also liked that the timeline is labeled in a way that cannot possibly be missed. I loved that you can choose so much stuff. If you select the menus on the bottom of the screen, you can choose to see geological features/events, fossil discoveries, and even where modern cities would be located. With so many choices, you just can't get bored! The app has a small problem though. While it is way better than any other app I tried, it does not allow you to scroll down on he timeline unless the entire era is visible. Other than that, it was superbly captivating and a great visual!
