- Inner Core. Temperature: 5,000°C – 6,000°C. State: Solid. Composition: iron and nickel. The Earth’s inner core is a huge metal ball, 2,500km wide. Made mainly of iron, the temperature of the ball is 5,000°C to 6,000°C – that’s up to 6,000 times hotter than our atmosphere and scorching enough to make metal melt!
- Outer Core. Temperature: 4,000°C – 6,000°C. State: Liquid. Composition: iron, nickel, sulphur and oxygen. This liquid layer of iron and nickel is 5,150km deep.
- Lower Mantle. Temperature: 3,000°C. State: solid. Composition: iron, oxygen, silicon, magnesium and aluminium. The lower mantle is found between 670km and 2,890km below the surface, and is made from solid rock.
- Upper Mantle. Temperature: 1,400°C – 3,000°C. State: liquid / solid. Composition: iron, oxygen, silicon, magnesium and aluminium. This layer is up to 670km below the Earth’s surface.
The Earth is a. planet. and is roughly the shape of a. sphere. There are three layers that make up the Earth’s structure. The three layers, starting from the outside, are: the crust – the ...

Temperature: 475 K (∼200°C) at the surface to1300 K (∼1000°C) Thickness: 25 miles (32 km) for continental crust and 3-5 miles (8 km) for oceanic crust Density: ∼ 2830 kg/m3 at the continental crust and ∼ 3000 kg/m3 at the oceanic crust It is the outermost and thinnest layer of our planet and is least dense among all other layers. Based on its thick...
Temperature: 1200 K (∼ 932°C) at the upper boundary with the crust to 1900 K (∼1652 °C) at the boundary with the lower mantle Thickness:255 miles (410 km) Density: ∼ 3400 kg/m3 It is the largest and thickest layer of earth. The upper mantle, along with the crust, makes up the lithosphere of earth, which is physically distinct from the layers lying ...
Temperature: 1900 K (∼ 1600°C) in the outer regions which can reach up to 4300 K (∼4000°C) at the bottom Thickness: 1,400 miles (2,250 km) Density: ∼ 4400 kg/m3 It is found below the upper mantle from a depth of about 400 miles (650 km) down to 1,800 miles (2,900 km) and is thus incredibly large and takes up most of the earth’s volume. Being so dee...
Temperature: 4,300 K (4,030°C) in the outer regions to 6,000 K (5,730°C) closest to the inner core Thickness:1,355 miles (2,180 km) Density: 9,900 – 12,200 kg/m3 Found below the mantle and having a composition similar to the inner core with 80% iron, along with nickel and some other lighter elements. The outer core has a very high density and thus ...
Temperature: 5,700 K (∼5,500°C) Thickness:760 miles (∼1,220 km) Density: 12,600 – 13,000 kg/m3 It is the center, and the hottest part of the earth. Similar to the outer core, the inner core is composed primarily of iron and nickel and has the highest density among all other layers. The inner core is made mostly metals such as gold, platinum, pallad...
Aug 1, 2023 · The outer core extends from 2,900 km to about 5,150 km beneath the Earth’s surface. It mainly consists of liquid iron and nickel. The motion within this layer generates the Earth’s magnetic field. The Inner Core. The inner core is the central part of the Earth. It extends from a depth of about 5,150 km to the Earth’s center at about 6,371 km.
Aug 8, 2023 · No, there are not eight layers of the Earth. Earth is made up of four distinct layers: the inner core, the outer core, the mantle, and the crust. The inner core is the deepest layer and has a solid inner core and a liquid outer core with a temperature range of 4400 °C to 6100 °C (7,952 °F to 11,012 °F).

Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
