Google Earth is a geobrowser that represents the earth as 3 dimensional globe using satellite and aerial imagery, ocean bathymetry and other geographic data over the internet. Google refers to this service as " geographic browser or geobrowser" and provides it to its users in two versions: One is free and the other is pro. Of course the paid version has more advanced features and functionalities, however, the free basic version is generous enough for us in education.
Google Earth provides search capabilities and the ability to pan, zoom, rotate, and tilt the view of the Earth. It also offers tools for creating new data and a growing set of layers of data, such as volcanoes and terrain, that reside on Google's servers, and can be displayed in the view. Educators around the globe have created engaging classroom activities that go beyond geography to teach literature, history, math, environmental science, and more.
