The crust of Earth is of two distinct types: Continental: 30 - 50 km (20 - 30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite. In a few places, such as the Tibetan Plateau, the Altiplano, and the eastern Baltic Shield, the continental crust is thicker (50 - 80 km (30 - 50 mi)).

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...
Jan 25, 2019 · The crust can be thicker than 80 kilometers in some spots and less than one kilometer thick in others. Underneath it lies the mantle, a layer of silicate rock approximately 2700 kilometers thick. The mantle accounts for the bulk of the Earth.

Aug 1, 2023 · The crust is the Earth’s outermost layer and it’s where we live. It has an irregular thickness, varying from about 5 km beneath the oceans (oceanic crust) to about 30 km beneath the continents (continental crust).
Oct 1, 2024 · Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. These crustal rocks both sit on top of the mantle, which is ultramafic in composition (i.e., very rich in magnesium and iron-bearing silicate minerals).
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.)
Learn about the three main layers of the Earth: crust, mantle, and core. The crust is thin and brittle, and varies in thickness from 5 km to 100 km depending on location.
