Despite considerable progress in seismology, mineral physics, geodynamics, paleomagnetism, and mathematical geophysics, Earth’s inner core structure and evolution remain enigmatic. One of the most significant issues is its thermal history and the curren
Seismic observations reveal that the Earth’s inner core oscillates with a period of approximately seven decades. The multidecadal periodicity coincides with that of several other geophysical observations, particularly the variations in the length of day
七选五体裁:说明文主题语境:宇宙探索The Earth's Inner CoreThe Earth's inner core, whose temperatures go beyond 5,000 degrees, may not present images of a winter wonderland.1 Before you rush to pack your skis, be aware that the “snowflakes (雪花)" are just composed of small pieces of ...
The core of the Earth is divided into two parts: the outer core and the inner core. What is the state of the outer core? A. Solid. B. Liquid. C. Gas. D. Plasma. 相关知识点: 试题来源: 解析 B。解析:地球的外核是液态的,这是因为外核的温度和压力条件使得物质呈现液态。A选项,固体...
The Earth’s inner core is separated from the rest of the planet by its liquid outer core, so it rotates at a different pace and direction.
