Title: Beringbooding Rock
Content: of a wave formation, caused by the same weathering patterns that created Wave Rock. The rock is used to collect water for the largest rock water catchment tank in Australia, holding around of water. The tank was built in 1937 using sustenance labour at a cost of £10,000. Two early pioneer wells are also found nearby. The area was known to Indigenous Australians as a reliable water source. Following European settlement prior to 1902 the wells near the rock were equipped with pumps in 1929 as part of the 3500 Farms Scheme to increase the number of settlers in the

Title: Hierve el Agua
Content: mountainside. The water has a temperature of . As the water runs down the rock face, it forms large stalactites similar to those found in caves. The flow of water from the spring varies significantly between the dry and rainy seasons. 95% of the surface rock formations are of calcium carbonate; however, lower layers of both rock and water currents are little known as they are sealed by the above layers. The calcium carbonate gives the formations a white or near white appearance, but other minerals that can be present in the water, such as silver, barium and iron can

Title: Cave
Content: rainwater and groundwater charged with HCO (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as "karst", characterized by sinkholes and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called "speleothems". The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Lechuguilla Cave in New Mexico and nearby Carlsbad Cavern are now believed to be examples of another

Title: Hot Springs National Park
Content: the park that are presumed to be flowing. Thermal water from 33 of the thermal springs is collected and monitored at a central reservoir, which distributes the combined discharge for public use and consumption. Rock types in the area include shale units which generally impede ground-water movement, while fractured chert, novaculite, and sandstone units generally support ground-water movement. The water comes from rain which falls in mountains to the north and northeast. Flowing downward through cracked rock at about one foot per year, the meteoric water migrates to estimated minimum depths of and achieves high temperatures in the deep section

Title: Hierve el Agua
Content: rock formations are on cliffs of mountains that rise abruptly from the narrow valley floor below. It is located in ethnic Mixe territory, with the two closest and most populous communities being San Lorenzo Albarradas and San Isidro Roaguia with populations of 1403 and 320 respectively (2005). The springs that produce the rock formations are one of the few water sources in the area. The site consist of two waterfall-like rock formations which have been formed over thousands of years. Both cliffs rise over fifty meters from the valley floor, with one rock formation reaching down twelve metres and the

Question: What name is given to the rock formations used as a source of water?
Answer: Aquifers
