臭氧层 (chòuyǎng céng) — ozone layer

臭氧层 (chòuyǎng céng)

臭氧层 refers to the ozone layer -- the region of Earth's stratosphere containing a high concentration of ozone (O3) that absorbs most of the Sun's ultraviolet radiation. It is a key term in environmental science and ecology.

Meanings

1. [noun] the ozone layer; the stratospheric ozone layer

Usage Notes

臭氧层 = 臭氧 (ozone) + 层 (layer). 臭氧 literally means "smelly oxygen" (臭 = smelly; 氧 = oxygen), reflecting the distinctive pungent smell of ozone. 层 (layer) is commonly used in Chinese for stratified structures: 大气层 (atmosphere), 臭氧层 (ozone layer), 冰层 (ice layer).

The topic of 臭氧层 often appears in HSK reading passages about environmental issues alongside 温室效应 (greenhouse effect), 全球变暖 (global warming), and 气候变化 (climate change). Knowing the key vocabulary of environmental harm (破坏, 损耗) and protection (保护, 恢复) is essential.

Memory Hook

臭 (smelly) + 氧 (oxygen) + 层 (layer) -- a layer of "smelly oxygen" high above us that shields us from the sun's harmful rays.
