Evolution of the Earth

How the Earth gradually formed from the primordial solar nebula, including basic information such as its size, mass, orbit, etc. Display important geological events in Earth's history, such as plate tectonics, volcanic eruptions, glacial periods, etc. Watch movies about the evolution of the Earth and learn about its formation. The Earth was formed approximately 4.6 billion years ago by the condensation of primitive nebulae. In the early stages, it was a hot magma ball, which gradually cooled down and gave rise to primitive oceans and atmospheres. During the Dark Ages, geological activity was frequent and there were also numerous impacts from celestial bodies. In the Archean, primitive life forms such as blue-green algae emerged, releasing oxygen to alter atmospheric composition. In the Proterozoic era, eukaryotic and multicellular organisms developed. Since the Phanerozoic era, biological evolution has accelerated: in the Paleozoic era, marine invertebrates flourished and fish landed; Dinosaurs dominated the Mesozoic era, and birds and mammals first appeared; The extinction of the new generation of dinosaurs, the rise of mammals, the flourishing of angiosperms, and ultimately the emergence of humans led to the evolution of the Earth into the vibrant and ecologically diverse form it is today.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
