|
|
asthenosphere
|
|
|
stiffer mantle
|
|
|
inner core
|
|
|
outer core

Explanation:
Detailed explanation-1: -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).
Detailed explanation-2: -The inner core experiences the highest pressure.
Detailed explanation-3: -Temperature in the inner core is about 5, 200° Celsius (9, 392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm). The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten.
Detailed explanation-4: -At a depth of about 5, 100 km (3, 200 miles), the outer core transitions to the inner core.
