This app is for all junior geologists. ***** Children's Technology Review Editor's Choice ***** The Earth is an interactive model that lets kids study geology and ecology. Kids explore and play with the geological forces that change the Earth—above and below the surface, in minutes and over millions of years. Kids can also learn about conservation as they test clean energy sources, clean up beaches, and preserve forests. The Earth is No. 5 in Tinybop’s Explorer’s Library. Each Explorer’s Library app lets kids explore the invisible and awesome wonders of STEM. Kids (and kids at heart!) develop foundational science literacy. "This is a great way to let children informally and playfully discover some of the big ideas they’ll encounter later on in their school curriculum. Apps like this one are good reminders for why you spent hundreds of dollars on a phone or tablet for your child." — Warren Buckleitner, editor, Children's Technology Review Features: * Investigate how landforms are created. * See the Earth transform over time, from a sphere of boiling rock to the continents we live on today. * Dig under the surface and observe the Earth’s layers from the crust to core. * Weather, erode, and deposit rocks and sediment. Shape the land with your fingertips! * Make a river meander. Make a glacier recede and advance. Create sand dunes, sea stacks, and beaches.
