Although the … WebJun 4, 2024 · The inner core is the innermost layer of the Earth, and is believed to be a solid ball composed of iron and nickel along with some light elements (e.g., oxygen, sulfur, silicon). It has an estimated radius of 1220 km (768 mi). Seismologist Inge Lehmann was the first to discover the inner core as being solid and covered by a liquid outer core.
WebThe Earth is made up of different layers: The inner core is in the centre and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to … WebThe inner core, with a radius of 1220 km, transmits S-waves at very low velocities, suggesting that it is a solid near the melting point or partly molten. It also displays anisotropy for P-waves, indicating it is composed of crystalline material.
