A valley is an elongated low area often running between hills or mountains and typically containing a ... flat-bottomed valley with an abrupt ending. Strike valley: ...
Strike and dip shown alongside cardinal directions on a horizontal plane. Z: strike line of the red plane, σ: strike angle, F: dip direction, φ: dip angle. The angle of the intersection with the green plane is the red plane's apparent dip in the northward direction
Along a strike valley, smaller tributaries feed into the steep slopes of mountainsides. These tributaries enter the main river about perpendicular, causing a trellis-like appearance of the system. They form where hard and soft formations exist on both banks of the main river, and are reflective of height, accentuated by erosion.
Photo of the fold looking south from the Strike Valley Overlook (USGS) The Laramide orogeny compacted the region from about 70 million to 50 million years ago and in the process created the Rocky Mountains. Many monoclines (a type of gentle upward fold in rock strata) were also formed by the deep compressive forces of the Laramide.
Tornado Alley, also known as Tornado Valley, is a loosely defined location of the central United States and Canada where tornadoes are most frequent. [1] The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas , Louisiana , Oklahoma , Kansas , South Dakota , Iowa and Nebraska .
A homoclinal ridge or strike ridge is a hill or ridge with a moderate, generally between 10° and 30°, sloping backslope. Its backslope is a dip slope , that conforms with the dip of a resistant stratum or strata , called caprock .
The valley has an average elevation of 2000 ft. Kangra Valley is a strike valley and extends from the foot of the Dhauladhar range to the south of river Beas. The highest peak on the Dhauladhar, White Mountain, marks the boundary between the valley and Chamba, and reaches 15,956 ft (4,863 m). The peaks of the range are approximately 13,000 ft ...
The Quaternary tectonics of the Death Valley area show the increasing impact of right-lateral strike-slip faulting. Death Valley itself is currently an active pull-apart basin developed between the Northern and Southern Death Valley Faults, with mainly normal faulting along the Black Mountains Fault zone between these two major strike-slip ...
