Geophysics is the science that studies the movements of parts of the Earth and the forces involved — the solid ground, the oceans, and the weather when people treat them as physical systems of the planet. It asks how the Earth works as a body: quakes, gravity, magnets, heat inside the planet, ice, tides.

Geophysics is the scienceGeophysics是一門科學 that studies the movements of parts of the Earth and the forces involved研究地球各部分的運動及其相關作用力 — the solid ground, the oceans, and the weather固體地面、海洋和天氣 when people treat them as physical systems of the planet當人們把它們當作地球的物理系統來看時。It asks how the Earth works as a body它探討地球作為一個整體是如何運作的: quakes, gravity, magnets, heat inside the planet, ice, tides地震、重力、磁力、地球內部的熱、冰、潮汐。

It sits next to geology, but geology often tells the story of rocks and time, while geophysics leans on physics: forces, waves, measurements. It is a formal, academic word for a whole field, like physics or chemistry.

It sits next to geology它跟geology（地質學）很相近, but geology often tells the story of rocks and time但地質學談的常是岩石與時間的故事, while geophysics leans on physics而geophysics則偏重物理: forces, waves, measurements力、波動、測量。It is a formal, academic word for a whole field這是一個正式、學術性的字，指一整個學門, like physics or chemistry就像physics（物理學）或chemistry（化學）一樣。

Though actually the umbrella is wide, and neighbouring sciences (oceanography, meteorology, geology) keep borrowing the same questions. In textbooks, geophysics is the name of the subject; in talk, people often just say 'Earth science' and let the details wait.

Though actually不過 the umbrella is wide這個領域的範圍很廣, and neighbouring sciences (oceanography, meteorology, geology) keep borrowing the same questions相鄰的學科（海洋學、氣象學、地質學）也一直在借用同樣的問題。In textbooks在教科書裡, geophysics is the name of the subjectgeophysics是這門學科的名稱; in talk在口語裡, people often just say 'Earth science' and let the details wait人們常常就說「地球科學」，細節先放一邊。
