Fold Mts
Fold Mts
define topography
the variations of land surface elevation caused by different land forms in a region
a series of steep-walled valleys lined with high cliffs, and the center is lower were it is sinking called a Graben
what is erosion
process of rock wearing away by gravity, flowing water, & wind
a large portion of rock deep under unsolidified sediment strata broke along a fault & rose or subsided;
a smooth motion of folding into a single step
define a mountain/hill
natural elevation of earth's surface rising to a summit
describe a Fault-Block Mt
mountains set apart by 1 + normal faults
what is another word for Deposition
Sedimentation
Describe the difference between Anticlines & Synclines
Anticlines are an arch in the rock layer, horizontal forces pushes rock upward
Synclines is a downward fold of rock strata; newer sediment in the center
the process of the earth's crust folding and deforming to make a mountain
What are the 2 types of Uplift Landforms & Describe each
Domes: forms when molten rock underground pushes up on a relatively small area of rock strata looking upside
Plateaus: sediment is undisturbed but lifted by some tectonic process
Describe Sedimentation
the slow build up material that was eroded
Describe Complex Tectonic Mountains
as 2 tect mts converge they produce piles of mountains with complex folds and faults
define Isostacy
balance of rock & water & ice weight
Basin: formed when magma chamber underground empties -
What are the 5 types of Erosional Mountains
mesas, buttes, talus, pinnacles, monadnocks

what is the difference between the Oceanic & Continental Crust
oceanic: thinner, denser, and colliding with cont. plates forming mts
Continental: thicker, less dense
What are Seamounts
extinct volcanoes in ocean basins
What are the 4 types of Depositional Hills & Mountains...
Moraines, Eskers, Kames, Drumlines
