Rift, английский
- Reactor in flight test
- The direction in which stone splits most readily; characteristic of granite or other stone not having visible stratification or foliation. rift-grained
Rift sawn, английский
Rift structure, английский
Rift system, английский
- The oceanic ridges formed where tectonic plates are separating and a new crust is being created; also, their on-land counterparts like the east african rift.
- A low land region of earth’s surface that can be as much as several kilometers deep, tens of kilometers wide and hundreds of kilometers long, such as the east african rift system. a rift system comprises a group of geological features that form due to tension (stretching) and subsidence (sinking) within or between tectonic plates. many geothermal power plants are located in rift systems because of their large geothermal gradients, high heat density, and networks of large fractures (e.g., buiter et al., 2022; goutorbe et al., 2011). superhot rock geothermal plays could occur in rift systems.
Rift zone, английский
Rifter-trimmer, английский
Rifting, английский
A plate tectonic process that creates a zone where the lithosphere has ruptured due to extension.
Valley, английский
- An elongated depression between uplands, hills, or mountains, esp. one following the course of a stream
- The "v" shaped area of a roof where two sloping roofs meet. water drains off the roof at the valleys.
- Долина
- The trough or gutter formed by the intersection of two inclined planes of a roof.
- A relatively shallow, wide depression on the sea floor, the bottom of which usually has a continuous gradient. this term is generally not used for features that have canyon-like characteristics. also called submarine valley or sea valley. cf. oceanic trench.
- An elongate, relatively large, externally drained depression of the earth`s surface that is primarily developed by stream erosion or glacial activity. compare - basin. hp
- Мрачное, страшное место или ситуация
Valley, английский
Valley air photos (firm), английский
Valley board, английский
In roofing, the board, nailed to the valley rafter, on which the metal gutter lies.
Valley braid; braid austral anastomosing branch; anabranch, английский
Valley brown ore, английский
Valley dam, английский
A tailings dam constructed by impoundment of a natural valley.
Valley fill, английский
The unconsolidated sediment deposited by any agent (water, wind, ice, mass wasting) so as to fill or partly fill a valley. hp
Valley flashing, английский
- Sheet metal that lays in the "v" area of a roof valley.
- The sheet metal used to line the valley on a roof. v 1035 vacuum breaker valley flashing
Valley flat, английский
A generic term for the low or relatively level ground lying between valley walls and bordering a stream channel; especially the small plain at the bottom of a narrow, steep-sided valley. the term can be generally applied noncommittally to a flat surface that cannot be identified with certainty as a floodplain or terrace. compare - backswamp, meander belt. gg
Valley floor, английский
A general term for the nearly level to gently sloping, lowest surface of a valley. landforms include axial stream channels, the flood plain, flood-plain steps, and, in some areas, low terrace surfaces.
Valley floor remnant, английский
Hills that are now erosion remnants of a former valley or basin floor, composed mostly of unconsolidated valley / basin fill sediments (e.g. alluvium) and typically lie well above the modern valley floor and flood plain. former basin floor surfaces have become dissected and irregular and consist of hillslope positions (shoulder, backslope, etc.) and hill components (interfluve, headslope, etc.); common in large valleys of the western us. sw
Valley gutter, английский
The open gutter in a valley; has sloping sides and is exposed to view.
