INDIAN GEOGRAPHY

Detailed explanation-1: -The outer core, is mainly liquid, is 2200 km thick in nature, whereas, the inner core is solid, and is 1270 km thick and that constitutes 3470 km thick as a whole. As one gradually moves upwards, one releases that the mantle and the core are divided by the line which is referred to as “Gutenberg discontinuity”.

Detailed explanation-2: -The middle layer, the mantle, is an average of 2900 km thick, and the core, the innermost layer, has an average radius of 3470 km, about the size of the planet Mars.

Detailed explanation-3: -Mantle – This is the layer below the crust. It is made up of molten or semi molten rock. This layer is 3, 000 km thick.

Detailed explanation-4: -Earth’s innermost layer is the core, which is separated into a liquid outer core and a solid inner core. The outer core is 2, 300 kilometers (1, 429 miles) thick, while the inner core is 1, 200 kilometers (746 miles) thick.

Detailed explanation-5: -The innermost part of the earth is referred to as the core and covers an area of around 3470 km thick.
