a.
To find: Ratio of Earth's total volume to the volume of Earth's inner core
Ratio of Earth's total volume to the volume of Earth's inner core is equal to
Given:
Earth's core is approximately spherical in shape and is divided into a solid inner core (the yellow region in the diagram shown) and a liquid outer core (the dark orange region in the diagram). Earth's radius is about
Calculation:
Given that Earth's radius is about 5 times as great as the radius of Earth's inner core.
The required ratio is
Hence the result is
b.
To find: The ratio of the volume of Earth's outer core to the volume of Earth's inner core.
The ratio of the volume of Earth's outer core to the volume of Earth's inner core is equal to
Given:
Earth's core is approximately spherical in shape and is divided into a solid inner core (the yellow region in the diagram shown) and a liquid outer core (the dark orange region in the diagram).
Calculation:
The required ratio is
Hence the result is
