| Earth Science |
- The spanish word for cauldron, a basin-shaped volcanic depression; by definition, at least a mile in diameter. such large depressions are typically formed by the subsidence of volcanoes. crater lake occupies the best-known caldera in the cascades.
- A collapsed or partially-collapsed seamount, commonly of annular shape.
- A large, more or less circular depression, formed by explosion and/or collapse, which surrounds a volcanic vent or vents, and whose diameter is many times greater than that of the included vent, or vents.

Depression, английский
- See low.
- The difference between dry and wet bulb temperatures. it is a measure of humidity.
- A severe economic slump.
- Депрессия, область пониженного давления; понижение, опускание
- 1. a mental condition that prevents someone from carrying out the normal activities of life in the usual way 2. a hollow on the surface of a part of the body
- Depresión
- [1] meteorology: an area of low barometric pressure—a bad weather system in which winds circulate clockwise in the southern and anticlockwise in the northern hemisphere (see coriolis effect). [2] physical geography: a depressed or sunken area lower than the surrounding surface. [3] astronomy. the angular distance of a celestial body below the horizon. [4] economics: a period during which business, employment, and stock-market values decline severely or remain at a very low level of activity. [5] general: the state of being depressed—sadness; gloom; dejection.
- Котловина, впадина; понижение
- Any relatively sunken part of the earth`s surface; especially a low-lying area surrounded by higher ground. a closed depression has no natural outlet for surface drainage (e.g. a sinkhole). an open depression has a natural outlet for surface drainage. compare - closed depression, open depression. gg

- Also called resolution. the fidelity with which detail is reproduced by a television system ranging from a fuzzy to a sharp appearance.
- The fidelity of reproduction of the pattern edge relative to the original master
- N дефиниция, определе- ние
- A verbal representation of a concept which serves to differentiate it from related concepts and allows humans to recognize and agree on the concept.
- Description of linear demarcation sensitivity or the detail sharpness of object outline in a radiologic test image. it is a function of screen type, exposure geometry, radiation energy, and characteristics sensor (such as film).
- Описание чувствительности к линейной демаркации или четкости контуров объекта на радиологическом контрольном изображении. это зависит от типа экрана, геометрии экспозиции, энергии излучения и характеристик датчика (например, пленки).
Subsidence, английский
- A sinking of an entire area, in contrast to the settlement of an individual structure. subsill 1. a subsidiary sill member fitted to a window frame; serves as a stop for screens; causes water to drip farther away from the wall surface; also called a sill drip molding. 2. a subsidiary doorsill which is fixed to the groundsill.
- Оседание, опускание. медленное опускание воз душной массы над большой территорией, обычно сопровож ю* is
- The sinking or caving in of the ground, or the settling of a structure to
- A low-lying area of ground formed by subsidence. synonyms:

Plug dome, английский
- The steep-sided, rounded mound formed when viscous lava wells up into a crater and is too stiff to flow away. it piles up as a dome-shaped mass, often completely filling the vent from which it emerged.
- A volcanic dome characterized by an upheaved, consolidated conduit filling. gg
Ring of fire, английский
- The regions of mountain-building earthquakes and volcanoes which surround the pacific ocean.
- Popular name for an arc stretching from new zealand, clockwise around the pacific ocean via the eastern edge of asia, north across the aleutian islands, and south along the coasts of the americas. it contains over 75 percent of the world’s active and dormant volcanoes. around the ring of fire, the pacific tectonic plate is colliding with and sliding underneath other plates. the tremendous amount of energy created by this tectonic activity melts rock into magma that rises to the surface as lava, forming volcanoes. ring-rope: a line rove through the ring of an anchor, passed through the hawse-hole, and made fast to the cable, to secure the anchor in foul weather.
