Terra firme (English spelling)

Japanese: テラ･フィルメ（英語表記）terra firme

Amazonia (Amazon River Basin) refers to highlands formed mainly from Tertiary deposits that do not flood even at the highest water level during floods. Meaning "hard ground," it is one of the two most typical landforms along with the várzea (floodplain). It occupies about 90% of the Amazon Basin and is covered with tropical rainforest, but the high temperature and heavy rainfall in the climate means that dissolved inorganic components are leached and organic matter is rapidly decomposed, making the soil essentially barren. In the terra firme, which is covered with tropical rainforest, in addition to traditional industries such as the harvesting of natural rubber and chestnuts, abundant forest resources and various mineral resources are being developed.

Japanese:

アマゾニア(アマゾン川流域)の，主として第三紀の堆積物から形成された，洪水時の最高水位でも浸水しない高地のこと。〈堅い土地〉の意で，バルゼア(氾濫原)とともに代表的な二つの地形の一つ。アマゾン盆地の約90％を占め，熱帯雨林に覆われているが，高温･多雨の気候下であるため，溶解質の無機成分が溶脱されたり，有機物が急速に分解されるので，土壌は本質的に不毛である。熱帯降雨林に覆われたテラ･フィルメでは，天然ゴムやパラ栗の採取など伝統的産業のほかに，豊富な森林資源や各種の鉱物資源の開発が行われている。
