Structural topography

Japanese: 構造地形 - こうぞうちけい

Landforms, the undulations and shapes of the Earth's surface, are controlled by three factors: the "structure" of the rocks that make up the Earth's surface crust, the "actions" acting on them from inside and outside the Earth, and the "time" of the formation of the landforms. Noting that landforms are closely related to the properties of rocks and geological structures, landforms related to geological structures such as faults and folds and the movements that create such geological structures (tectonic movements) were generally called "structural landforms" until the mid-20th century. However, most of the structural landforms studied by European and American geomorphologists were eroded landforms that reflected differences in the resistance of rocks to erosion, especially geological structures that were formed in ancient geological times.

地球表面の起伏，形態である地形は，地殻表層部を構成する岩石の〈構造〉と，そこに働く地球内部および外部からの〈作用〉と，地形形成の〈時間〉の三つの因子によって支配されている。地形が岩石の性質や地質構造と深い関係にあることに注目して，断層や褶曲などの地質構造やそうした地質構造を造る運動(造構造運動)に関係した地形を，20世紀中ごろまで一般に〈構造地形〉とよんでいた。しかし，欧米の地形学研究者によって調べられていたそれらの構造地形の大部分は，浸食に対する岩石の抵抗性の差異，とくに古い地質時代に形成された地質構造を反映した浸食地形であった。
