In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent less often, used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases.
A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber/reservoir in a volcanic eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface. Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Only seven caldera-forming collapses are known to have occurred since 1900, most recently at Bárðarbunga volcano, Iceland in 2014.
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the upper mid-east region of North America that connect to the Atlantic Ocean through the Saint Lawrence River. In general, they are on or near the Canada–United States border. They are lakes Superior, Michigan, Huron, Erie, and Ontario. Hydrologically, there are only four lakes, because lakes Michigan and Huron join at the Straits of Mackinac. The Great Lakes Waterway enables travel by water between the lakes.

Lake Constance refers to three bodies of water on the Rhine at the northern foot of the Alps: the Obersee or Upper Lake Constance, the Untersee or Lower Lake Constance, and a connecting stretch of the Rhine, called the Seerhein. These waterbodies lie within the Lake Constance Basin, which is part of the Alpine Foreland and through which the Rhine flows.
Lake Tahoe is a large freshwater lake in the Sierra Nevada of the United States. Lying at 6,225 ft (1,897 m), it straddles the state line between California and Nevada, west of Carson City. Lake Tahoe is the largest alpine lake in North America, and at 122,160,280 acre⋅ft (150.7 km3) trails only the five Great Lakes as the largest by volume in the United States. Its depth is 1,645 ft (501 m), making it the second deepest in the United States after Crater Lake in Oregon.
A body of water or waterbody is any significant accumulation of water, generally on a planet's surface. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption. A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany.
Lake Starnberg, or Starnberger SeeGerman pronunciation (help·info)) — called Lake Würm, or Würmsee, until 1962 — is Germany's second-largest body of fresh water, having great depth, and fifth-largest lake by area. It and its surroundings lie in three different Bavarian districts, or Landkreise. The lake is property of the state and accordingly managed by the Bavarian Administration of State-Owned Palaces, Gardens and Lakes.

The Großer Plöner See or Lake Plön is the largest lake (30 km²) in Schleswig-Holstein, Germany. It is located near the town of Plön. Its main tributary, as well as its main outflow, is the River Schwentine.
A lake is an area filled with water, localized in a basin, 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, although like the much larger oceans, they form part of earth's water cycle. Lakes are distinct from lagoons which are generally coastal parts of the ocean. They are generally larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing in a channel on land. Most lakes are fed and drained by rivers and streams.

Lille Lungegårdsvannet or Smålungeren is a small 5 acres (0.020 km2) lake in the centre of the city of Bergen in Vestland county, Norway. The octagonal lake is a natural lake that was historically connected to the nearby Store Lungegårdsvannet bay via a short strait, but the strait was filled in 1926. Today the lake is located in a park in the city centre. There is a large decorative fountain located in the central part of the lake.
Strandavatnet is a lake in Hol municipality, Norway. The lake covers an area of 23.75 square kilometres (9.17 sq mi), and lies 975 metres (3,199 ft) above sea level.' The lake is a reservoir for the Rud hydroelectric powerstation in Hovet, Buskerud. In 1952/1953 a dam was constructed which lifted the lake level 28 meters, thus the lake varies between 950 and 978 m above sea level.
