By holding the joystick, visitors unlocks the Earth device and intuitively explores the mysterious structures inside the Earth. The three circles within the Earth include the crust, mantle, and core. The interactions between these different layers enable the existence and continuation of life on Earth. The internal structure of the Earth presents a concentric ring structure, consisting of the core, mantle, and crust from the center to the surface. The crust and mantle are separated by the Moho discontinuity, while the mantle and core are separated by the Gutenberg discontinuity. Push the push rod to understand the internal structure of the Earth. The "heart" of the Earth is the Earth's core, which has an internal temperature of approximately 6000 ℃. The outer core is composed of molten or nearly liquid substances, while the inner core is composed of solid substances. The mantle is located beneath the Earth's crust and is composed of hot magma and other materials, in a slowly moving state. The mantle is mainly composed of solid matter, with an overall thickness of over 2800 kilometers, accounting for approximately 82.26% of the Earth's volume. According to the differences in the composition of mantle materials, divide the mantle into.
