|
They were formed in different geologic eras.
|
|
|
They are divided by a layer of partly molten material called the mesosphere.
|
|
|
They exist in different states of matter.
|
|
|
They have a different chemical composition.
|
Detailed explanation-1: -They have a different chemical composition. They were formed in different geological eras.
Detailed explanation-2: -Scientists believe that the Earth’s inner core is solid, while its outer core is liquid. That’s because the inner core is under a lot more pressure than the outer core.
Detailed explanation-3: -The inner core is under intense pressure, which keeps it solid despite high temperatures. Outer Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick. Both the inner and outer cores consist primarily of iron and nickel and are extremely hot with temperatures ranging from 7200–9000℉ (4000–5000℃).
Detailed explanation-4: -Scientists divided the layers because of each of the layers have different temperatures, minerals, and elements that are needed to create each layer.
Detailed explanation-5: -The core was discovered in 1936 by monitoring the internal rumbles of earthquakes, which send seismic waves rippling through the planet. The waves, which are much like sound waves, are bent when they pass through layers of differing densities, just as light is bent as it enters water.
