Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. The outer core begins approximately 2,889 km (1,795 mi) beneath Earth's surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath Earth's surface at the inner core boundary. Webb13 feb. 2024 · 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, which are summarized in Table 14.1. 3.

WebbWhat is the difference between the inner and outer core of the Earth? A) The inner core is liquid and the outer core is solid. B) The inner core is made from magma and the outer core is metal. C) The inner core is solid and the outer core is liquid. D) The inner core is cool and the outer core is hot. WebbThe earth can be divided into four concentric zones (Figure ). The innermost is called the inner core and is thought to be a solid, spherical mass of iron. Its radius is about 1,216 kilometers (730 miles). The next zone, called the outer core, is believed to be a layer of molten liquid rich in nickel and iron that is about 2,270 kilometers (1,362 miles) thick. shapes bluebeam
