Geographical Features
Well, ravines are sometimes called valleys, and mountains can be called hills or heaps of earth... but they are usually called mountains and ravines. You could also call them landforms, or even landmarks if they are sufficiently unique.
Regions of land with similar landforms are called physiographic provinces or landform regions. These are areas characterized by distinct geological features such as mountains, valleys, or plains. They are typically identified based on similarities in landforms resulting from common geological processes.
These features are called topographic features or landforms. They include mountains, valleys, hills, plains, plateaus, and other physical characteristics of the Earth's surface.
Mountains
Large plains between mountains are typically referred to as valleys or basins. Valleys are elongated lowlands surrounded by higher terrain, while basins are more bowl-shaped depressions enclosed by higher land. Both landforms are common features in mountainous areas.
Earth's surface features are called landforms, which include mountains, valleys, plains, plateaus, and other physical formations formed by various geological processes such as erosion, volcanic activity, and tectonic movements.
An area of relatively level high ground is called a plateau. Plateaus are elevated flat landforms that stretch over a large area and are often situated between valleys and mountains.
Plateau, peak and slope. Valleys are the area between these forms.
