Types of Landforms - TSV

Landform classification is a system that categorizes the relief and shape of Earth's surface by morphology, formation process, and scale. Various landforms such as mountains, plains, basins, valleys, lakes, wetlands, dunes, and glaciers are formed by endogenic processes (crustal movement, volcanic activity) and exogenic processes (weathering, erosion, deposition). The Geospatial Information Authority of Japan classifies landforms into natural and artificial types, organized in three hierarchical levels: detailed, regional, and broad-area versions.

code	slug	name	description	category	formationProcess
01	mountain-range	Mountain Range	A large-scale landform consisting of continuous mountains.	Mountainous Terrain	Crustal Movement (Endogenic Process)
02	plain	Plain	A vast, flat landform with minimal relief.	Lowland	Deposition (Exogenic Process)
03	basin	Basin	A depression-like landform surrounded by mountains or hills.	Depression	Crustal Movement and Erosion (Endogenic and Exogenic Processes)
04	valley	Valley	A valley landform formed by river erosion through mountains or hills.	Valley Landform	Fluvial and Glacial Erosion (Exogenic Process)
05	lake	Lake	A natural body of water surrounded by land.	Water Body	Structural, Volcanic, Glacial, and Depositional Processes
06	wetland	Wetland	Lowland with high groundwater levels, constantly saturated with water.	Back Marsh and Wetland	Poor Drainage and Depositional Processes
07	dune	Dune	A landform formed by wind-deposited sand accumulation.	Sandbar and Dune	Aeolian Process (Exogenic Process)
08	glacier	Glacier	A massive body of ice formed by compacted snow.	Glacial Landform	Glacial Process (Climatic Process)
