this word describes things that belong to geology這個字用來形容屬於geology地質學的東西 the rocks, soil, and other materials that make up the Earth也就是構成地球的岩石、土壤和其他物質 and the way they have changed since the Earth was formed以及地球形成以來它們變化的方式

A geological map does not show roads and cities first; it shows what kind of rock lies under your feet, and how old it is. A geological survey means people going out to study the ground itself. A geological timescale is not in years you can feel — it is in millions of years.

a geological map一張geological地圖 does not show roads and cities first不會優先標出道路和城市 it shows what kind of rock lies under your feet, and how old it is而是顯示你腳下是什麼樣的岩石、有多老 a geological survey一次geological調查 means people going out to study the ground itself就是有人實際去研究地面本身 a geological timescale一個geological時間尺度 is not in years you can feel不是你感覺得到的那種年份 it is in millions of years而是以百萬年為單位

So the adjective does not mean “the study” by itself; it means “of that study / of those rocks and that long change.” Though actually, English speakers also stretch it as a joke. “I haven't cleaned this in geological time” means “for a ridiculously long time.” That use is playful.

so the adjective does not mean “the study” by itself所以這個形容詞本身不是指「這門學問」 it means “of that study / of those rocks and that long change.”而是指「屬於那門學問／那些岩石和那段漫長變化的」 though actually不過其實 English speakers also stretch it as a joke英文使用者也會拿它開玩笑 “I haven't cleaned this in geological time”「I haven't cleaned this in geological time」 means “for a ridiculously long time.”意思是「久到誇張」 that use is playful這種用法是開玩笑的

In school and science it stays close to rocks and Earth history. Do not use it when you mean geographic (about places and maps). A geographic border is on a map; a geological fault is a crack in the rock.

in school and science在學校和科學裡 it stays close to rocks and Earth history它還是緊扣岩石和地球歷史 do not use it when you mean geographic當你想說的是geographic（跟地方、地圖有關）時不要用它 a geographic border一條geographic的邊界 is on a map是在地圖上 a geological fault而一個geological的斷層 is a crack in the rock則是岩石裡的裂縫
