Do do you ever wonder what earth looked like 1,000 years ago? 1 million years ago? Even 10 million years ago? With earth viewer, the earth can be seen how it is today, and up to 4,500 million years ago; plus any year in between. When you open the application, you will be stunned at the 3-D graphics of the globe which takes up more then half of your screen. Located on the left side of your device is a bar marked off with years and time periods. Take a step into the past with a quick pinch and pull of the timeline. Earth viewer will allow users to grasp a firm understanding of earth from the beginning of time.
Both children and adults of all ages will enjoy the extravagant graphics along with the straightforward quality of the app. Earth Viewer is an easy way to comprehend valuable information on prehistoric earth within minutes. Users can effortlessly pinch and pull at the globe to inspect different time periods in a more precise way. Another pinch and pull to the timeline located on the left grants you the power to inspect a time period in a more exact way, or even in a wider range depending on what information you're seeking. A swipe along that same timeline makes your globe slowly transform and shape shift as it once did millions of years ago. Located on the very bottom of your screen in another thin grey bar that allows you to comfortably change the information that appears scattered amongst your globe. Things such as mass extinction, major impact events, fossil discoveries and current city whereabouts in the past can be chosen to shown and not shown with the click of a button. Instead of a key, Earth Viewer provides small icons scattered about the globe that when tapped upon give you a brief summary on the happenings of that place throughout time. Additional information included in the app is amount of O2 and CO2 in the air, day length and also the direction of continents at different periods in time.
I highly recommend this app for children and adults above 5th grade. Earth Viewer provides an easy learning environment for most ages in a way that will intrigue all sorts of buyers. Whether you're looking for a quick lesson to teach to your students or just some fun facts, Earth Viewer is a basic learning tool that will always have you returning to the app for more.
