地球的内部结构

一张地球科学信息图,把地球的分层画成四分之一球体的剖切楔形。同心色带——地壳、上地幔、下地幔、外核、内核——从冷灰的地壳渐变到炽热发白的地核,每层标注深度、温度与状态(固态或液态)。细白引线连向右侧数据列。半写实渐变插画,深色星空背景。左上角粗体标题「地球的内部结构」,配一根以千米为单位的小比例尺。

An earth-science infographic showing the layers of the Earth as a cutaway quarter-sphere wedge. Concentric bands - crust, upper mantle, lower mantle, outer core, inner core - are color-coded from cool crust-grey to a glowing white-hot core, each labeled with depth, temperature and state (solid or liquid). Thin white leader lines connect to a right-hand data column. Semi-realistic gradient illustration on a dark starry background. Bold title 'Inside Our Planet' top-left, a small scale bar in kilometers.
