Fajã
() is a Portuguese term of obscure origin used to describe supratidal talus at the foot of coastal cliffs, caused by landslides or lava flows.G. Lameiras et al. (2009), p.827 Although relatively common world-wide, they are distinctive features of the Azores and Madeira, as well as of the Canary Islands, where the equivalent term in Canarian Spanish is (). The term also designates a small flat piece of land, generally cultivable and located by the sea, formed of materials fallen from cliffs. Another Canarian word for lava is , literally, "low island". Geology Fajãs are created from collapsing cliffs or lava flows and are identifiable along the coast as "flat" surfaces, relative to other geological forms. Tides and tidal currents have only minor influence on coastal morphology, and therefore sedimentation and deposits there became permanent. Composed of fertile soils, these microclimates allow the cultivation of a variety of staple and exotic plants, such as coffee. Azor ...

Fajã Dos Cubres
The Fajã dos Cubres is a permanent debris field, known as a fajã, built from the collapsing cliffs on the northern coast of the civil parish of Ribeira Seca, in the municipality of Calheta, island of São Jorge, in the Portuguese archipelago of the Azores. History The spit received its name from the seaside goldenrod ('' Solidago azorica''), a small yellow flowering plant, that is common to the fajã. This species, common along the eastern coast of the United States, spread throughout many of the islands of the archipelago. The size of the fajã has been attributed to the 9 July 1757 earthquake, considered the most violent tectonic quake that occurred in the Azores.Amigos dos Açores (2013), p.16 This seismic event was characterized by violent movements of land (landslides, collapses and rockfalls) that were responsible for the creation of several fajãs on the island, such as the Fajã of Ponta Nova, and the growth of pre-existing fajãs. The event, and associated aftersh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fajã Do Ouvidor
The Fajã do Ouvidor is a permanent lava field originated (we think) from Pico da Esperança when was active, and the most recent from the collapsing cliffs on the northern coast of the civil parish of Norte Grande, in the municipality of Velas, island of São Jorge, in the Portuguese archipelago of the Azores. History The fajã received its name due to its association with Valério Lopes de Azevedo, the magistrate/superintendent of the Donatary-Captain at the time, who was one of the principal property-owners. During the 17th century, a whale-watching hut was established on the flanks of the fajã in order to spot whales transiting the northern coast. Fisherman from Ouvidor and surrounding settlements would then leave their homes in order to hunt whales: due to the decline of whaling the outpost was abandoned. There is one religious meeting-point in the fajã: the Hermitage of Nossa Senhora das Dores, which dates to 1903, and includes old images created in the parish of No ...

Vineyards
A vineyard (; also ) is a plantation of grape-bearing vines, grown mainly for winemaking, but also raisins, table grapes and non-alcoholic grape juice. The science, practice and study of vineyard production is known as viticulture. Vineyards are often characterised by their ''terroir'', a French term loosely translating as "a sense of place" that refers to the specific geographical and geological characteristics of grapevine plantations, which may be imparted to the wine itself. History The earliest evidence of wine production dates from between 6000 and 5000 BC. Wine making technology improved considerably with the ancient Greeks but it wasn't until the end of the Roman Empire that cultivation techniques as we know them were common throughout Europe. In medieval Europe the Church was a staunch supporter of wine, which was necessary for the celebration of the Mass. During the lengthy instability of the Middle Ages, the monasteries maintained and developed viticultural prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Yam (vegetable)
Yam is the common name for some plant species in the genus '' Dioscorea'' (family Dioscoreaceae) that form edible tubers. Yams are perennial herbaceous vines cultivated for the consumption of their starchy tubers in many temperate and tropical regions, especially in West Africa, South America and the Caribbean, Asia, and Oceania. The tubers themselves, also called "yams", come in a variety of forms owing to numerous cultivars and related species. Yams were independently domesticated on three different continents: Africa (''Dioscorea rotundata''), Asia (''Dioscorea alata''), and the Americas (''Dioscorea trifida''). Etymology The name "yam" appears to derive from Portuguese ''inhame'' or Canarian (Spain) ''ñame'', which derived from West African languages during trade. However in both languages, this name commonly refers to the taro plant (''Colocasia esculenta'') from the genus ''Colocasia'', as opposed to '' Dioscorea''. The main derivations borrow from verbs me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Diffraction
Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word ''diffraction'' and was the first to record accurate observations of the phenomenon in 1660. In classical physics, the diffraction phenomenon is described by the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets. The characteristic bending pattern is most pronounced when a wave from a coherent source (such as a laser) encounters a slit/aperture that is comparable in size to its wavelength, as shown in the inserted image. This is due to the addition, or interference, of different points on the wavefront (or, equivalently, each wavelet) that travel by paths of d ...

Refraction
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence ''θ1'' and angle of refraction ''θ2'' is equal to the ratio of phase velocities (''v''1 / ''v''2) in the two media, or equivalently, to the refractive indices (''n''2 / ''n''1) of the two media. :\frac =\frac=\frac Optical prisms and lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
