Jan 23, 2020 · Shown is a colour illustration of Earth's layers, shown as if the globe has been sliced to show the inside. The right half of the globe is a photograph of Earth, with oceans, continents, and white swirling clouds. The left half is a half circle with six layers. These are labelled and illustrated using the colours from the diagram above.
- 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.
- Upper Mantle. 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)
- Lower Mantle. 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)
- Outer Core. 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.
Layers of the earth diagram. View in 3D. Layers of the Earth. The Earth has three main layers: the crust, the mantle and the core. The three layers of the Earth are. The Crust. The crust is the outermost layer of the Earth, is around 5-70 km thick, and is made of rocky material. The crust is thicker below the continents than the ocean floor.

Nov 11, 2019 · Mountain ranges tower to the sky. Oceans plummet to impossible depths. Earth’s surface is an amazing place to behold. Yet even the deepest canyon is but a tiny scratch on the planet. To really understand Earth, you need to travel 6,400 kilometers (3,977 miles) beneath our feet. Starting at the center, Earth is composed of four distinct layers.

The mantle is the second chemical layer of the earth. It is composed of mostly melted rocks, depending on where you are in the depth of the earth. It’s the most abundant of all the layers of the earth – it makes up almost 85% of the volume of the globe. It’s difficult to study the mantle because there is no way to physically view it.
