The outer core of the earth
Webb7 apr. 2024 · The Core is made up of two layers, the inner core and outer core. Seismic evidence tells us that the inner core is solid while the outer core is liquid. The inner core has a radius of 1 216 km and the total radius of the core is 3486 km. The core is composed mostly of iron (80%) and some nickel. WebbThe outer core is the layer surrounding the inner core of the earth. It is a liquid layer, also made up of iron and nickel. It is still extremely hot, with temperatures similar to the inner core.

The outer core of the earth
Did you know?
WebbThe outer core is Earth’s internal layer that is liquid. This is because Earth is hotter toward its center due to heat left over from the formation of the planet and also the decay of radioactive elements. These high temperatures at the center of the planet cause rocks to be completely melted. WebbThe temperature in the core ranges from 4400°C to about 6000°C. Pressure and density increases towards the interior of the earth. The inner core is in solid state due to high pressure and density which compresses the molten rock material. Outer core is in liquid state as there is not enough pressure to keep it in a solid state. Question 4
WebbThere are four main layers that make up the Earth: crust, mantle, outer core, and inner core. We are quite familiar with the first layer, the crust, since we walk on it every day, dig holes in it, and so on.

WebbFör 1 dag sedan · Inner Core: The innermost part of Earth is the core and is about 1500 miles (2414 km) thick. Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging from 7200–9000℉ (4000–5000℃). The inner core is under intense pressure, which keeps it solid despite high temperatures.
