A maar is a broad, low relief volcanic crater that is caused by a phreatomagmatic eruption, an explosion caused by groundwater contact with hot lava or magma. Daun is a municipality in the German state of Rhineland-Palatinate (Rheinland-Pfalz seat of the district Vulkaneifel in the volcanic Eifel A relief is a Sculptured Artwork where a modeled form is raised (or alternatively lowered from a flattened background without being disconnected from it A volcanic crater is a circular depression in the ground caused by volcanic activity Phreatomagmatic eruptions are defined as juvenile forming eruptions as a result of interaction between water and Magma. An explosion is a sudden increase in Volume and release of Energy in an extreme manner usually with the generation of high Temperatures and the release Groundwater is Water located beneath the Ground surface in Soil pore spaces and in the Fractures of lithologic formations Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures Magma (Plurals magmas and magmata) is molten rock that sometimes forms beneath the surface of the Earth (or any other Terrestrial planet The maar typically fills with water to form a relatively shallow crater lake. Water is a common Chemical substance that is essential for the survival of all known forms of Life. Crater Lake is a Caldera Lake located in the US state of Oregon. The name comes from a local Palatinate German dialect of Daun, which is in turn derived from Latin mare (sea). Palatine German ( Pfälzisch / Pälzisch or Pfaelzisch / Paelzisch) is a West Franconian dialect of German which is spoken A dialect (from the Greek word διάλεκτος dialektos) is a variety of a Language that is characteristic of a particular group of Daun is a municipality in the German state of Rhineland-Palatinate (Rheinland-Pfalz seat of the district Vulkaneifel in the volcanic Eifel Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. This article is about the body of water For other uses see SEA and Seas. Maars are shallow, flat-floored craters that scientists interpret as having formed above diatremes as a result of a violent expansion of magmatic gas or steam; deep erosion of a maar presumably would expose a diatreme. A scientist, in the broadest sense refers to any person that engages in a systematic activity to acquire Knowledge or an individual that engages in such practices A diatreme is a breccia filled Volcanic pipe that was formed by a gaseous explosion This page is about the physical properties of gas as a state of matter Uses A Steam engine uses the expansion of steam in order to drive a Piston or Turbine to perform Mechanical work. Erosion is the carrying away or displacement of solids ( Sediment, Soil, rock and other particles usually by the agents of currents such as wind Maars range in size from 60 meters (200 ft) to 2000m (6,500ft) across and from 10 meters (30ft) to 200 meters (650ft) deep, and most are commonly filled with water to form natural lakes. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International A lake (from Latin lacus) is a Terrain feature (or Physical feature) a body of Liquid on the surface of a world that is localized to the Most maars have low rims composed of a mixture of loose fragments of volcanic rocks and rocks torn from the walls of the diatreme. Volcanic rock is an Igneous rock of volcanic origin Texture Volcanic rocks are usually fine-grained or Aphanitic to glassy in In Geology, rock is a naturally occurring aggregate of Minerals and/or Mineraloids The Earth's outer solid layer the ‘ Lithosphere

Hole-in-the-Ground, in Oregon, a maar crater

The maar at Birket Ram, the Golan Heights

Maars occur in western North America, in the Eifel region of Germany (where they were originally described), and in other geologically young volcanic regions of Earth. Hole-in-the-Ground is a large Maar (explosion crater in the Fort Rock Basin of Lake County, central Oregon, northeast of Crater Lake Oregon ( is a state in the Pacific Northwest region of the United States. Borders of Israel The Golan Heights ( الجولان al-Jawlān, הגולן ha-Golan) is a strategic Plateau and mountainous The Eifel is a low mountain range in western Germany. It occupies parts of southwestern North Rhine-Westphalia and northwestern Rhineland-Palatinate Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. Geology (from Greek γη gê, "earth" and λόγος Logos, "speech" lit EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 Kilbourne Hole and Hunt's Hole, near El Paso, Texas, are maars. Kilbourne Hole is a Maar volcanic crater located west of the Franklin mountains of El Paso Texas, in the Potrillo Volcanic Field of Doña Ana County The notorious, carbon dioxide-saturated Lake Nyos in Africa is another example. Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single Lake Nyos is a Crater lake in the Northwest Province of Cameroon. An excellent example of a maar is Zuni Salt Lake in New Mexico, a shallow saline lake that occupies a flat-floored crater about 6,500 feet (1,980 m) across and 400 feet (120 m) deep. Zuni Salt Lake, also Zuñi Salt Lake or Fence Lake ( Navajo: Áshįįh) is a rare high desert lake and a classic Maar. New Mexico ( is a state located in the southwestern region of the United States of America. The salt lake or saline lake is a landlocked body of Water which has a concentration of Salts (mostly Sodium chloride) and other minerals significantly Its low rim is composed of loose pieces of basaltic lava and wallrocks (sandstone, shale, limestone) of the underlying diatreme, as well as random chunks of ancient crystalline rocks blasted upward from great depths. Basalt (bəˈsɔːlt ˈbeisɔːlt ˈbæsɔːlt is a common Extrusive Volcanic rock. Sandstone is a Sedimentary rock composed mainly of Sand -size Mineral or rock grains. Shale (also called mudstone) is a fine-grained Sedimentary rock whose original constituents were Clay minerals or Muds It is characterized by Limestone is a Sedimentary rock composed largely of the Mineral Calcite ( Calcium carbonate: CaCO3 The only maar-like volcano known in Canada is found in the Wells Gray-Clearwater Volcanic Field in east-central British Columbia.
