A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest , with the terrain dropping down on either side.
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Guyot – Isolated, flat-topped underwater volcano mountain; Hanging valley – A tributary valley that meets the main valley above the valley floor; Headland – Landform extending into a body of water, often with significant height and drop
A landform is a natural or anthropogenic [1] [2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain , and their arrangement in the landscape is known as topography .
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Landform comprising an immense pile of calcareous material previously accumulated on an ancient sea floor. Reef knolls can be divided into bioherms and biostromes. A bioherm is a landform of organic sedimentary rock enclosed or surrounded by rock of different origins. A biostrome is a distinctly bedded or broadly lenticular sedimentary rock ...
Dinosaur Ridge is only a short segment of the Dakota Hogback that extends the length of the Front Range from Wyoming to southern Colorado. [6] The Grand Hogback is a 70-mile long (110 km) ridge located in western Colorado. [7] It marks part of the boundary between the Colorado Plateau to the west and the Southern Rocky Mountains to the east. [8]
In later years, newer technology was able to date the rocks and identified that rocks closest to the ridge were younger than the rocks near the coasts of the Western and Eastern Hemispheres land. At present, marine geology focuses on geological hazards, environmental conditions, habitats, natural resources, and energy and mining projects. [10]
The Gakkel Ridge (formerly known as the Nansen Cordillera and Arctic Mid-Ocean Ridge) [1] is a mid-oceanic ridge, a divergent tectonic plate boundary between the North American Plate and the Eurasian Plate. [2] It is located in the Eurasian Basin of the Arctic Ocean, between Greenland and Siberia.
