Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Mountain research, traditionally also known as orology [1] (from Greek oros ὄρος for 'mountain' and logos λόγος), is a field of research that regionally concentrates on the Earth's surface's part covered by mountain environments.
The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters.
In this satellite image of the Alps, the snow limit picks out the individual mountain chains A view of the Balkan Mountains chain. The chain-like arrangement of summits and the formation of long, jagged mountain crests – known in Spanish as sierras ("saws") – is a consequence of their collective formation by mountain building forces.
The length of the Academy of Sciences Range is about 110 km. The crest of the range has an Alpine-like relief with 24 summits more than 6,000 m in height. The lowest saddle point, Kamaloyak (Камалояк), is at the altitude of 4,340 m (14,240 ft).
A spur is a lateral ridge or tongue of land descending from a hill, mountain or main crest of a ridge. [1] [2] It can also be defined as another hill or mountain range which projects in a lateral direction from a main hill or mountain range. [3] Examples of spurs include:

For example, the world's second-highest mountain is K2 (height 8,611 m, prominence 4,017 m). While Mount Everest 's South Summit (height 8,749 m, prominence 11 m [ 2 ] ) is taller than K2, it is not considered an independent mountain because it is a sub-summit of the main summit (which has a height and prominence of 8,848 m).
