A
The description of a region's geologic features, including height.
Topography
These are both landforms that rise above the surrounding terrain of an area.
Mountains and hills
Features on the Earth Surface (a general term)
Landforms
The buildup of sediment over time is known as...
Sedimentation or Deposition
These mountains are carved out by extensive erosion.
Erosional mountains
This is measured from the base of a mountain.
Actual Height
Two important processes that shape and create mountain landforms.
Erosion and deposition
True or False: Actual height of a mountain can be measured starting from below seal level.
True
This is measured from actual sea level.
Elevation
Pebbles, sand, an silt that are formed from a sliding glacier scraping bedrock is known as this.
Glacial Till
Which landform is both a tectonic and depositional landform?
Volcanic mountains
This is a depositional landform created by wind.
Sand Dunes
Long, low ridges of glacial till that form at the front and sides of glaciers.
Moraines
A trough, or downward fold of rock strata.
Syncline
The erosion of ___________ has created mesas, buttes, pinnacles, and arches.
Plateaus
This balancing force accounts for the thickness of the lithosphere anywhere on Earth.
Isostasy
Massive erosion, tectonic processes, and volcanic activity can create _____________.
Monadnocks OR Volcanic Necks
The tectonic process that forms mountains.
Orogeny
The area in the center of a rift where rocks have cracked and dropped downward.
Grabens
An arch of rock layers pushed into an upward fold and often tilting towards one side.
Anticlines
Circular structures where rock strata were uplifted in the middle, dipping away from the center of the formation.
Domes
These zones produce fold mountains.
Convergent tectonic zones.
Tension in the earth's crust can form these types of mountains. It results from a landmass on one side of a fault rising above a landmass on the other side of the fault.
Fault-block mountains
These zones produce rift valleys, surrounded by steep, rugged cliffs.
Divergent tectonic zones.
Circular structures where rock strata sagged, dipping toward the center of a formation.
