Question:

List the layers of the Earth from coolest to warmest with temperatures.

Layers of the Earth:

There are four different layers that make up the Earth. These layers are the inner core, outer core, mantle, and crust. The crust is the outermost and thinnest layer. The mantle is below the crust and is the thickest layer of the Earth. Next are the outer core and the inner core, which is the deepest part of the Earth. The outer layers are made up of lighter materials, such as rock (basalts and granites). The inner layers are made up of heavy metals (nickel and iron).

Answer and Explanation:

The Earth's layers from coolest to hottest are: crust, mantle, outer core, and inner core.

The crust's temperature can vary from the air temperature on top of the crust to 1600 degree Fahrenheit. Rocks can melt at that temperature. The mantle's temperature is usually somewhere between 1600 degrees Fahrenheit and 4000 degrees Fahrenheit. The outer core varies from 4000 degrees Fahrenheit to 9000 degrees Fahrenheit. Metals are in liquid state at that temperature. The inner core's temperature is usually around 9000 degrees Fahrenheit.
