Mountains & Hills
The differences of land elevations in a region
What is topography?
Mountain landforms that are made of anticlines and synclines
What are fold mountains?
A large area of flat, elevated land
What is a plateau?
Broad, flat-topped hills remaining from the erosion process with steep, cliff-like sides; probably formed as waters from the Flood receded
What are mesas and buttes? (Buttes are usually smaller mesas.)
Plateau
What is an uplift landform?
The height of a mountain's peak above average sea level
What is elevation?
Most rift zones are located here
Mountains formed by the eruption of molten rock on the earth's surface from deep tectonic zones
What are volcanoes?
Sloped piles of broken rock
What is talus?
Basin
Mountain landforms that result from forces within the crust
What are tectonic mountains?
A series of steep-walled valleys lined with high cliffs rising from faults parallel to the valley
What is a rift?
This uplift landform has sedimentary strata and looks like an upside-down bowl
What is a dome?
The ability of wind and water to transport sediment is most directly related to this
What is their speed?
Monocline
What is a convergent landform?
Two factors that distinguish a hill from a mountain
What are height and tradition (of the region)?
In this type of mountain fold, the older exposed rocks lie to both sides of the fold
What is a syncline?
An extinct underwater volcano
What is a seamount?
long, low hills made of glacial till
What are drumlins?
Drumlins and sand dunes
What are a depositional landforms?
The longest and most extensive mountain system on the earth
What is the Mid-Atlantic Ridge?
A normal fault that formed deep under a series of overlying rock strata could result in this step-like fold
What is a monocline?
This subsidence landform occurs when a magma chamber deep underground empties, and the overlying rock strata sag into a bowl-shaped structure
What is a basin?
Kames and eskers are made up of this
What is glacial till?
Butte
What is an erosional landform?
The term for the study of mountain-building processes
What is orogeny?
Mountains set apart by one or more normal fualts
What are fault-block mountains?
Most folded sedimentary rock strata are smoothly shaped, because the strata were still __________ when they were folded quickly.
What is soft?
This is formed when magma pushes upward into sedimentary rock which erodes away leaving the solidified magma
What is a monadnock?
Graben
What is a divergent landform?
