Which layer of Earth is the:

Thinnest-
Thickest-
Most massive-
Hottest-
Most dense-

Thinnest layer of Earth:

The thinnest layer of Earth is the crust, which varies in thickness from around 5-70 kilometers (3-43 miles).

Thickest layer of Earth:
The thickest layer of Earth is the mantle, which extends from the crust to the outer core and has an average thickness of approximately 2,900 kilometers (1,800 miles).

Most massive layer of Earth:
The most massive layer of Earth is the mantle, which accounts for about 84% of the Earth's total mass.

Hottest layer of Earth:
The hottest layer of Earth is the innermost layer, the inner core. It has temperatures estimated to reach around 5,400 degrees Celsius (9,800 degrees Fahrenheit).

Most dense layer of Earth:
The most dense layer of Earth is the inner core. Although it is solid, it is the densest part of the Earth due to the immense pressure present at the core, with an average density of approximately 13 grams per cubic centimeter.
