Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor to ice as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation.
The Arctic is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska, Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost containing tundra. Arctic seas contain seasonal sea ice in many places.
The Himalayas, or Himalaya, are a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the highest, Mount Everest. Over 100 peaks exceeding 7,200 m (23,600 ft) in elevation lie in the Himalayas. By contrast, the highest peak outside Asia is 6,961 m (22,838 ft) tall.
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east.
The Jasmund National Park is a nature reserve on the Jasmund peninsula, in the northeast of Rügen island in Mecklenburg-Vorpommern, Germany. It is famous for containing the largest chalk cliffs in Germany, the Königsstuhl. These cliffs are up to 161 m (528 ft) above the Baltic Sea. The beech forests behind the cliffs are also part of the national park.
Supercooling, also known as undercooling, is the process of lowering the temperature of a liquid or a gas below its freezing point without it becoming a solid. It achieves this in the absence of a seed crystal or nucleus around which a crystal structure can form. The supercooling of water can be achieved without any special techniques other than chemical demineralization, down to −48.3 °C (−55 °F). Droplets of supercooled water often exist in stratus and cumulus clouds. An aircraft flying through such a cloud sees an abrupt crystallization of these droplets, which can result in the formation of ice on the aircraft's wings or blockage of its instruments and probes.
Carpobrotus edulis is a ground-creeping plant with succulent leaves in the genus Carpobrotus, native to South Africa. It is known as hottentot-fig, sour fig, ice plant or highway ice plant.
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martin in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of the mainland Antarctica.
The Antarctic realm is one of eight terrestrial biogeographic realms. The ecosystem includes Antarctica and several island groups in the southern Atlantic and Indian oceans. The continent of Antarctica is so cold that it has supported only 2 vascular plants for millions of years, and its flora presently consists of around 250 lichens, 100 mosses, 25-30 liverworts, and around 700 terrestrial and aquatic algal species, which live on the areas of exposed rock and soil around the shore of the continent. Antarctica's two flowering plant species, the Antarctic hair grass and Antarctic pearlwort, are found on the northern and western parts of the Antarctic Peninsula. Antarctica is also home to a diversity of animal life, including penguins, seals, and whales.
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season.
The University of California Botanical Garden is a 34-acre botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon. The Garden is in the Berkeley Hills, inside the city boundary of Oakland, with views overlooking the San Francisco Bay. It is one of the most diverse plant collections in the United States, and famous for its large number of rare and endangered species.
Stadials and interstadials are phases dividing the Quaternary period, or the last 2.6 million years. Stadials are periods of colder climate while interstadials are periods of warmer climate.
Bear Rocks are a widely recognized symbol of West Virginia wilderness and among the most frequently photographed places in the state. They are a well-known landmark on the eastern edge of the plateau that includes the Dolly Sods Wilderness. They sit in a high-elevation heathland punctuated with wind-carved sandstone outcrops and is home to more than a dozen rare plant and animal species. Situated on the crest of the Allegheny Front, Bear Rocks afford vistas over the South Branch Potomac River. Visibility can extend eastward to the Shenandoah National Park in Virginia.
A milk substitute is any substance that resembles milk and can be used in the same ways as milk. Such substances may be variously known as non-dairy beverage, nut milk, grain milk, legume milk, mock milk and alternative milk.
Inga is a genus of small tropical, tough-leaved, nitrogen-fixing trees and shrubs, subfamily Mimosoideae. Inga's leaves are pinnate, and flowers are generally white. Many of the hundreds of species are used ornamentally.
Ice Mountain is a mountain ridge and algific talus slope that is part of a 149-acre (60 ha) preserve near the community of North River Mills in Hampshire County, West Virginia, United States. It was designated a National Natural Landmark in 2012.
The Ross expedition was a voyage of scientific exploration of the Antarctic in 1839 to 1843, led by James Clark Ross, with two unusually strong warships, HMS Erebus and HMS Terror. It explored what is now called the Ross Sea and discovered the Ross Ice Shelf. On the expedition, Ross discovered the Transantarctic Mountains and the volcanoes Erebus and Terror, named after his ships. The young botanist Joseph Dalton Hooker made his name on the expedition.
House of Flavors is a manufacturer of ice cream based in Ludington, Michigan. It started as a dairy business as part of a farm operation before 1930. In 1935 the business had become known as Miller's Dairy and started expanding the operation. By the 1940s they processed milk, buttermilk, cottage cheese, and ice cream. In the late 1940s a businessman with a decade of dairy experience moved to Ludington from a city 60 miles south to become a partner of the existing business. He became the general manager and the name was changed to Park Dairy. The milk and butter segments of the business were sold off and the enterprise concentrated from then on into just making ice cream.
The International Center for Ethnobotanical Education, Research, and Service (ICEERS) is a non-profit organization (NPO), headquartered in Barcelona. ICEERS is dedicated to transforming society's relationship with psychoactive plants by engaging with some of the fundamental issues resulting from the globalization of ayahuasca, iboga, and other ethnobotanicals. Founded in 2009, ICEERS is registered as a non-profit organization, and has charitable status in the Netherlands and Spain, and through partner organizations in the US and UK. ICEERS also has consultative status with the United Nations’ ECOSOC.
Glaciofluvial deposits or Glacio-fluvial sediments consist of boulders, gravel, sand, silt and clay from ice sheets or glaciers. They are transported, sorted and deposited by streams of water. The deposits are formed beside, below or downstream from the ice. They include kames, kame terraces and eskers formed in ice contact and outwash fans and outwash plains below the ice margin. Typically the outwash sediment is carried by fast and turbulent fluvio-glacial meltwater streams, but occasionally it is carried by catastrophic outburst floods. Larger elements such as boulders and gravel are deposited nearer to the ice margin, while finer elements are carried farther, sometimes into lakes or the ocean. The sediments are sorted by fluvial processes. They differ from glacial till, which is moved and deposited by the ice of the glacier, and is unsorted.
