The Earth Surface

What materials make up earth?What are earth’s plates? and how the earth’s crust moves?
In this Earth surface 3d interactive app users can find answers to the above questions in high quality 3D graphic video. This app is part of K-12 science curriculum.
Apart from the video, In the interactive simulation users can view different cross section views of earth surface and its layers crust, mantle, outer core, and inner core
In this app, users can also create an earth by combining different layers of earth

Earth has three layers the crust,the mantle, and the core. Rock of the crust and upper makes up plates that fit together like puzzle pieces. Earth’s plates collide, pull apart, and slide past each other. Most mountains and volcanoes form at plate boundaries. Many earthquakes also occur at plate boundaries.
