“地核”的英语表达是 “the Earth's core” 或更简洁的 “the core of the Earth” ,也可直接表述为 “core” (在上下文明确指地球核心时)。
the Earth's core:这是最常用且正式的表达,强调地核属于地球这一主体。例如:Scientists are still trying to understand the composition and temperature of the Earth's core.(科学家们仍在努力了解地核的成分和温度。)
the core of the Earth:与“the Earth's core”意思相近,这种表述更侧重于描述地核在地球结构中的位置关系。例如:The core of the Earth is divided into the outer core and the inner core.(地核分为外核和内核。)
core:在特定语境下,当对话或文本围绕地球结构展开,上下文已明确提及地球时,可直接用“core”指代地核。例如:In geology, the core is the innermost part of the Earth.(在地质学中,地核是地球的最内部。)
