Description of the earth's outer core
WebThe crust, the mantle, and the core are the three layers that make up the earth. The core only forms 15 per cent of the Earth’s volume, whereas the mantle occupies 84 per cent. The remaining 1 per cent is made up of the crust. From the picture, we see that at the centre of the Earth lies the core, then there is the mantle and finally the crust.

WebSep 13, 2024 · Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small rocky core. Near the core, it heats up to 9,000 degrees Fahrenheit (4,982 degrees Celsius). WebThe Earth The structure of the Earth comprises of the crust, mantle, outer core and inner core. The crust and upper part of the mantle are broken into tectonic plates.
WebThe inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core. In fact, Earth's outer core is approximately 5 to 10 percent lower density than iron at Earth's core temperatures and pressures. Hence it has been proposed that light elements with low atomic numbers comprise part of Earth's outer core, as the only feasible way to lower its density.
