Please answer the following question: Information:  - A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams.  - Snow pertains to frozen crystalline water throughout its life cycle, starting when it precipitates from clouds and accumulates on surfaces, then metamorphoses in place, and ultimately melts, slides or sublimates away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold enough for year-to-year accumulation, a glacier may form. Otherwise, snow typically melts, seasonally, and causes runoff into streams and rivers and recharging groundwater.  - North Rhine-Westphalia (, commonly shortened to NRW) is the most populous state of Germany, with a population of approximately 18 million, and the fourth largest by area. Its capital is Düsseldorf; the most populous city is Cologne. Four of Germany's ten largest citiesCologne, Düsseldorf, Dortmund, and Essenare located within the state, as well as the largest metropolitan area on the European continent, Rhine-Ruhr.  - Vulkaneifel is a district ("Kreis") in the northwest of the state Rhineland-Palatinate, Germany. It is the least densely populated district in the state and the fourth most sparsely populated district in Germany. The administrative centre of the district is in Daun. Neighboring districts are Euskirchen (North Rhine-Westphalia), Ahrweiler, Mayen-Koblenz, Cochem-Zell, Bernkastel-Wittlich, and Bitburg-Prüm.  - Jünkerath is an "Ortsgemeinde"  a municipality belonging to a "Verbandsgemeinde", a kind of collective municipality  in the Vulkaneifel district in Rhineland-Palatinate, Germany. It belongs to the "Verbandsgemeinde" of Obere Kyll, and is home to its seat.  - Groundwater (or ground water) is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.  - A Verbandsgemeinde (plural Verbandsgemeinden) is an administrative unit in the Germanfederal states of Rhineland-Palatinate and Saxony-Anhalt.   - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf.  - A glacier (or ) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.  - Ormont is an "Ortsgemeinde"  a municipality belonging to a "Verbandsgemeinde", a kind of collective municipality  in the Vulkaneifel district in Rhineland-Palatinate, Germany. It belongs to the "Verbandsgemeinde" of Obere Kyll, whose seat is in the municipality of Jünkerath.  - The Eifel is a low mountain range in western Germany and eastern Belgium. It occupies parts of southwestern North Rhine-Westphalia, northwestern Rhineland-Palatinate and the south of the German-speaking Community of Belgium.  - Snowpack forms from layers of snow that accumulate in geographic regions and high altitudes where the climate includes cold weather for extended periods during the year. Snowpacks are an important water resource that feed streams and rivers as they melt. Therefore, snowpacks are both the drinking water source for many communities and a potential source of flooding (in case of sudden melting). Snowpacks also contribute mass to glaciers in their accumulation zone.  - The German-speaking Community of Belgium (, "DG"; ) is one of the three federal communities of Belgium. Covering an area of within the province of Liège in Wallonia, it includes nine of the eleven municipalities of the so-called East Cantons. Traditionally speakers of Low Dietsch, Ripuarian and Moselle Franconian varieties, the local population numbers over 75,000about 0.70% of the national total.  - Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany.  - The Rhine (, , ) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the  Swiss-Austrian, Swiss-Liechtenstein, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands.  The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about , with an average discharge of about .  - Rhineland-Palatinate (German: "Rheinland-Pfalz") is one of the 16 states (German: "Länder", lit. "countries" however better translated as "state") of the Federal Republic of Germany. It has an area of and about four million inhabitants. Its state capital is Mainz. Rhineland-Palatinate is located in western Germany and borders Belgium, Luxembourg and France, and the German states of North Rhine-Westphalia, Hesse, Baden-Württemberg and Saarland.  - Prüm is a town in the Westeifel (Rhineland-Palatinate), Germany. Formerly a district capital, today it is the administrative seat of the "Verbandsgemeinde" ("collective municipality") Prüm.  - Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.  - The Schneifel is a range of low mountains , up to 699.1 m above sea level ( NHN ) , in the western part of the Eifel in Germany , near the Belgian border . It runs from Brandscheid near Prüm in a northeasterly direction to Ormont . The name Schneifel has nothing to do with the German words Schnee ( snow ) and Eifel . It is derived from the former dialect of this region and means something like Schneise ( `` swathe '' ) . This swathe ran over the mountains . The term was `` Germanised '' during the Prussian era and the term Schnee - Eifel ( `` Snow Eifel '' ) was born , albeit referring to a larger area . Winters in this low mountainous region are unusually cold and snowy for western and parts of central Europe and snow lies here for longer than anywhere else in the Eifel . As a result , the winter sports season is longer here than in the surrounding region . The highest point of the Schneifel is the 699.1 - metre - high Schwarze Mann ( `` Black Man '' ) , which is also the third highest point of the Eifel range after the Hohe Acht and the Erresberg ( Ernstberg ) . There is a winter sports area on the Schwarze Mann with the same name . The Schneifel is covered along its entire length by the ruins of bunkers which formed part of the Siegfried Line . On the heights of the Schneifel is the former US radar station , Prüm Air Station , and the Schnee Eifel transmission tower for terrestrial TV and VHF which , with a height of 224 m is clearly visible for miles .
