Earth's Structure and Properties

The video tutorial explores the structure of Earth, describing its spherical shape and surface components like air, water, and land. It delves into the internal layers, including the crust, mantle, and core, and explains the process of ice melting into water due to heat energy. The tutorial uses a peach as a model to illustrate Earth's structure, highlighting the crust, mantle, and core's characteristics and temperatures.
