Arrange the layers of the Earth in order from the outermost to innermost
The layers of the Earth, from the outermost to innermost, are as follows:
1. Crust: This is the outermost layer of the Earth. It is the thinnest layer, ranging from about 5 to 70 kilometers thick beneath the continents and about 5 to 10 kilometers thick beneath the oceanic crust.
2. Mantle: The mantle lies beneath the crust and is the largest layer of the Earth. It extends from about 35 kilometers beneath the oceanic crust to over 2,890 kilometers deep. The mantle is composed of solid rock that can flow slowly over long periods of time.
3. Outer Core: The outer core is a liquid layer composed mostly of molten iron and nickel. It lies beneath the mantle, starting approximately 2,890 kilometers deep and extending to around 5,150 kilometers deep.
4. Inner Core: The inner core is the innermost layer of the Earth, located at the very center of the planet. It is a solid layer composed mostly of iron and nickel due to extreme pressure. The inner core starts around 5,150 kilometers deep and extends to the Earth's center, at approximately 6,371 kilometers.
