|
the thin and solid outermost layer
|
|
|
the innermost layer of iron and nickel
|
|
|
the hot layer of rock (magnesium and oxygen) between the crust made of silica and oxygen and the core made of iron and nickel
|
|

Explanation:
Detailed explanation-1: -Layers based on chemical composition are the core, mantle and crust. According to mechanical properties, Earth’s layers are the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core, according to Phys.org (opens in new tab).
Detailed explanation-2: -The Mantle It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavy weight. This flow is due to great temperature differences from the bottom to the top of the mantle.
Detailed explanation-3: -The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick!
