terrain = terr(土地) + ain(表名词) = 地形，地势
terrace = terr(土地) + ace(名词词尾) = 层层叠叠的土地→梯田
monster = mon(警告) + ster(表名词) = （怪兽）出现需要警告→怪兽

alluvial = al(临近) + luv(流) + ial(形容词) = 流到近处来→冲积的
congenial = con(共同) + gen(产生) + ial(形容词) = 产生共同[兴趣]→情投意合的
土地上的→地球上的
terrestrial
常考释义
Stone meteorites, if they lie around exposed to the weather for a few years, well, they’re made of rock, so they end up looking almost indistinguishable from common terrestrial rocks, ones that originated on earth.
