Geomorphology Flashcards
is a coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate
Sabkha
is a type of glacial outburst flood that is associated with glacial sedimentation
Jokulhlaups
any tributary stream that runs parallel to, and within the floodplain of a larger river for considerable distance, before eventually joining it
Yazoo
Kaolinite-rich mudrocks formed by volcanic processes
Tonsteins
A volcanic caldera that has been partially filled by a new central cone.
Somma Volcano
Formations where valley glaciers leave mountains and spread on a flatland as large lobes of spreading ice
Piedmont glacier
A ridge that descends towards a valley floor or coastline from a higher elevation, that ends in an inverted V face produced by the erosional truncation of the spur by the action of either streams, waves, or glaciers.
Truncated Spur
Rock outcrops that have been partially or completely covered by ice caps due to topography.
Nunataks (see Rognons also)
Etched, pitted, grooved, fluted and otherwise rugged surfaces formed from weathered limestone.
Shilin/Karren/Lapies/Pinnacle Karst
stream channels with flat floors and steep walls of sediment usually found in deserts or other arid climates and completely dry up between periods of activity due to water-less conditions.
Arroyo
Linear dunes that form from constant wind direction and with no vegetation
Seif/longitudinal dune
Also known as Burringurrah and is known as the largest rock. It is an inselberg.
Mt. Augustus
The second “step” of the Colorado Plateau
Vermillion Cliffs National Monument
What structure carved the Grand Canyon?
Colorado River
A city built on a spit within the Manila Bay
Cavite City
What type of structure is Devil’s Tower, Wyoming, USA
Volcanic Neck
A duricrust rich in aluminum, commonly in the form of hardened bauxite
Alcrete
The loss of silica and concentration of sesquioxides in the soil, with the formation of gibbsite, and with or without the formation of laterite.
Allitization (see also. Soluviation, feralization, laterization, and latosolization)
a sharp-edged gap that forms between two cirques converging from opposite sides of a crest
Col
A deep crack in the brittle surface of a glacier
Crevasse
While both a.) ________ and b.)_________ are streamlined and oriented in the direction of glacial movement, they differ in their composition and formation process. A a.) __________ is composed of bedrock and formed by deformation, while a b.) _________ is composed of till and formed by deposition.
a.) Roche moutonnee
b.) Drumlin
lakes occur in a series down a formerly glaciated valley in small basins scooped out by the glacier as it retreated
Paternoster lake
The steep sides of a mesa are called
escarpments or scarps
In geology, what is a ‘boss’?
a. isolated hill in arid region
b. isolated hill over a peneplain
c. small igneous intrusion
d. a small, rounded mound or mass of resistant bedrock
a small, rounded mound or mass of resistant bedrock
In geology, the term boss can indeed refer to a small igneous intrusion, typically characterized as a rounded mass of resistant rock that has been exposed through erosion. However, it’s important to clarify that while a boss can be considered an igneous intrusion, it is specifically described as a small, rounded mound or mass of resistant bedrock.
