Example:
Imagine trying to find a warm spot on a cold winter's day by wrapping yourself in layers of blankets. Just like those blankets create a series of layers to keep you warm, the Earth is composed of several layers, with its innermost layer being the dense sphere of solid iron and nickel known as the inner core. The blankets are analogous to the Earth's outer layers, like the crust and mantle, insulating and protecting the solid inner core, which is akin to your body being kept warm at the center of all those blankets.
