Feb 2, 2023 · All the Earth’s Layers, Their Structure and Composition. 1. Crust. Temperature: 475 K (∼200°C) at the surface to 1300 K (∼1000°C) Thickness: 25 miles (32 km) for continental crust and 3-5 miles (8 km) for oceanic crust. Density: ∼ 2830 kg/m 3 at the continental crust and ∼ 3000 kg/m 3 at the oceanic crust. It is the outermost and ...
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 ...
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.
May 8, 2018 · The Earth is made up of three major layers. Planet Earth is one of the unique planets in the Solar System because of the presence of abundant water resources to sustain life. It may seem like the Earth is made up of a single layer of a big solid rock. However, that is not true. The Earth is actually composed of several parts and layers, some of ...

- 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.
Apr 30, 2023 · It makes up 55% of Earth by volume and experiences pressure from 237,000 atm to 1.3 million atm towards the outer core. Heat and pressure in the lower mantle are much greater than in the upper mantle.

Jan 21, 2023 · Chemical Composition of the Earth. The earth is composed of 90 chemical elements, of which 81 have at least one stable isotope. The unstable elements are 43 Tc and 61 Pm, and all elements heavier than 83 Bi. Note that the vertical axis is logarithmic, which has the effect of greatly reducing the visual impression of the differences between the ...
