The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...
Apr 30, 2023 · The Earth's layers are caused by what the Earth is made of and how it formed. The core is made of metal (mostly iron), while the rest of the Earth is made of rock, and metal and rock don't mix ...
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 ...

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...
2 days ago · Earth - Core, Mantle, Crust: More than 90 percent of Earth’s mass is composed of iron, oxygen, silicon, and magnesium, elements that can form the crystalline minerals known as silicates. Nevertheless, in chemical and mineralogical composition, as in physical properties, Earth is far from homogeneous. Apart from the superficial lateral differences near the surface (i.e., in the compositions ...
Nov 11, 2019 · This solid metal ball has a radius of 1,220 kilometers (758 miles), or about three-quarters that of the moon. It’s located some 6,400 to 5,180 kilometers (4,000 to 3,220 miles) beneath Earth’s surface. Extremely dense, it’s made mostly of iron and nickel. The inner core spins a bit faster than the rest of the planet.

Dec 8, 2023 · Oxygen (O): Oxygen is the most abundant element in Earth’s composition, making up approximately 46.6% of the Earth’s crust by weight. It is a crucial component of minerals and compounds, such as silicates and oxides. Silicon (Si): Silicon is the second most abundant element in the Earth’s crust, accounting for about 27.7% of its ...
