Apr 25, 2024 · Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of Earth is a hot, dense metal core.
Earth's crust is its thick outer shell of rock, referring to less than one percent of the planet's radius and volume. It is the top component of the lithosphere, a solidified division of Earth 's layers that includes the crust and the upper part of the mantle. [1] .

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 22, 2024 · The Earth’s outermost layer—its crust—is rocky and rigid. There are two kinds of crust: continental crust , and ocean crust . Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica.

Nov 20, 2024 · Chemically, Earth can be divided into three layers. A relatively thin crust, which typically varies from a few kilometres to 40 km (about 25 miles) in thickness, sits on top of the mantle. (In some places, Earth’s crust may be up to 70 km [40 miles] thick.)
Earth’s outer surface is its crust; a cold, thin, brittle outer shell made of rock. The crust is very thin, relative to the radius of the planet. There are two very different types of crust, each with its own distinctive physical and chemical properties.
