the outer core is liquid; the inner core is solid
The existence of a solid inner core distinct from the liquid outer core was discovered in 1936 by seismologist Inge Lehmann
The distinction of the solid inner core from the liquid outer core of Earth was discovered in 1936 by Inge Lehmann. Inge Lehmann is a seismologist.
The scientific name for the Earth's inner core is "Earth's solid inner core."
The British geologist Richard Dixon Oldham discovered the Earth's core and published his results in 1906.
The inner core.
The inner core
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
the solid inner core and the liquid outer core
True, honey! Scientists have indeed discovered that the Earth's core has two parts by studying earthquake waves. We've got the inner core, which is solid as a rock, and the outer core, which is liquid and sloshing around like a lava lamp. So, buckle up, buttercup, because the Earth's core is a wild ride of hot messiness!
