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. Zobacz więcej 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) … Zobacz więcej Composition Earth's outer core cannot be entirely constituted of iron or iron-nickel alloy because their densities are higher than geophysical … Zobacz więcej Unlike Earth's solid, inner core, its outer core is liquid.

Witryna11 lis 2024 · Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. In fact, the deepest humans have ever drilled is just over 12 kilometers (7.6 miles).
