Explanation:
Detailed explanation-1: -Mantle is the thickest layer of earth at 2900km.
Detailed explanation-2: -The Earth’s thickest layer is the mantle, which stretches a bit over 1, 800 miles in thickness. This layer makes up nearly 85% of the Earth. It’s situated between the crust and the outer core.
Detailed explanation-3: -Mantle-2, 900 km thick. Outer Core-2, 200 km thick. Inner Core-1, 230 to 1, 530 km thick.
Detailed explanation-4: -The thickness of the upper mantle is about 640 km (400 mi). The entire mantle is about 2, 900 km (1, 800 mi) thick, which means the upper mantle is only about 20% of the total mantle thickness.
