It is approximately 2,300 km thick. The outer core is mainly composed of iron and nickel and is completely in liquid form. The outer core is responsible for Earth's magnetic field. Due to this high temperature, the outer core is liquid despite being made up of iron and nickel. Crossing the outer core, we reach the hottest part of the planet, which is the inner core. Why does the inner core is solid state though the temperature is very high? While 4350 K is believed to be a typical temperature within the outer core, 116 GPa is slightly lower than the pressure expected at the top of the outer core.

According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form. Since the inner core is super heated the iron and nickel are in molton form in the outer core. Found insideIt may seem surprising that the inner core is solid, because it should be at a higher temperature than the liquid outer core. Thus the effects of pressure ... The inner core is solid metal. In contrast, when the intake valve is closed (or when it's open and you're considering the outer non-luminous flame), the oxygen for the combustion reaction comes from the surrounding air, which is not thoroughly mixed with the gas at the time of ignition. Found inside – Page 372As the core cools , the inner core grows . ( b ) The inner and outer core have different chemical compositions and hence different melting temperatures . solid.

Extending outwards from the core are the mantle and the crust. There needs to be a 2,700-degree F (1,500 C) difference between the . Moving from the inner core outward, the temperature of Earth's layers tends to decrease. The pressure in the Earth's inner core is slightly higher than it is at the boundary between the outer and inner cores: it ranges from about 330 to 360 gigapascals (3,300,000 to 3,600,000 atm). The outer core is is 2,2,300 300 km thick. The book is a collaboration of faculty from Earth Science departments at Universities and Colleges across British Columbia and elsewhere"--BCcampus website. This layer is cooler but still very hot, perhaps 7,200 to 9,000 degrees Fahrenheit (4,000 to 5,000 degrees Celsius). Various lines of evidence (mostly from the seismic waves generated by earthquakes) suggest that the inner core of the Earth is solid. The outer core lies under the mantle, and is 1,400 miles thick. Question Date: 2015-01-14: Answer 1: Good question! Temperature: 5,000 degrees Celsius. The inner core is in solid state and the outer core is in the liquid state (or semi-liquid). The core has two parts; the liquid outer core surrounds a solid inner core. A pressure-density model of the outer core is assumed, and the corresponding observed seismic velocity distribution is compared to that calculated from shock-wave theory, for assumed values of Hugoniot parameters and Grueneisen's ratio.
