地表

地表 refers to the surface of the earth, typically the outer layer of the planet's crust. It is used in both literal and metaphorical contexts, often contrasting with underground or subterranean areas.

The character 地 (dì) means 'earth' or 'ground,' while 表 (biǎo) means 'surface' or 'outer layer.' Together, they form a term that literally translates to 'earth's surface,' emphasizing the visible, tangible part of the land.

地表 is commonly used in geography, geology, and everyday language. It can also appear in expressions like 地表温度 (surface temperature) or 地表水 (surface water). In modern Chinese, it is often used in scientific or technical contexts, but it also appears in literature and casual speech to describe the physical world above ground.
