Loam in the context of "Hesbaye"

Mudbrick or mud-brick, also known as unfired brick, is an air-dried brick, made of a mixture of mud (containing loam, clay, sand and water) mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE.

From around 5000–4000 BCE, mudbricks evolved into fired bricks to increase strength and durability. Nevertheless, in some warm regions with very little timber available to fuel a kiln, mudbricks continued to be in use. Even today, mudbricks are the standard of vernacular architecture in some warmer regions- mainly in parts of Africa and western Asia. In the 20th century, the compressed earth block was developed using high pressure as a cheap and eco-friendly alternative to obtain non-fired bricks with more strength than the simpler air-dried mudbricks.

There are 13 lakes of at least five acres (two hectares) within the borders of Minneapolis in the U.S. state of Minnesota. Of these, Bde Maka Ska is the largest and deepest, covering 421 acres (170.37 ha) with a maximum depth of 89.9 feet (27.4 m). Lake Hiawatha, through which Minnehaha Creek flows, has a watershed of 115,840 acres (468.79 km), two orders of magnitude larger than the next largest watershed in the city. Ryan Lake, in the city's north, sits partially in Minneapolis and partially in neighboring Robbinsdale. Certain other bodies of water are counted on some lists of Minneapolitan lakes, though they may fall outside the city limits or cover fewer than five acres.

Many of Minneapolis's lakes formed in the depressions left by large blocks of ice after the retreat of the Laurentide Ice Sheet at the end of the last glacial period and now overlie sandy or loamy soils. Before the appearance of white settlers, the Dakota harvested wild rice from the lakes. In the early 1800s, the lakes' shorelines were marshy, deterring large-scale settlement and development by white residents though an experimental Dakota agricultural community, Ḣeyate Otuŋwe, was founded on the banks of Bde Maka Ska by Maḣpiya Wic̣aṡṭa in 1829. In the 1880s, landscape architect Horace Cleveland foresaw Minneapolis's growth and made a series of recommendations to the city's Board of Park Commissioners to acquire land along Minnehaha Creek, near Minnehaha Falls, and around several lakes in the southwest portion of the city in order to form a robust, interconnected park system that would aesthetically and morally benefit the city's residents. Board president Charles M. Loring heeded Cleveland's advice and bought the land, later developed into a robust system of parks by Theodore Wirth. During this time, many of the lakes were reformed by the Board of Park Commissioners through draining, dredging, shoreline stabilization, and the construction of parkways around their perimeters. Property in neighborhoods surrounding the lakes grew desirable, especially by the "Chain of Lakes", five lakes in the southwestern portion of the city (Maka Ska, Harriet, Isles, Cedar, and Brownie) that were joined by artificial channels.

Nelumbo nucifera, also known as Padma (Sanskrit: पद्म, romanized: Padmā, lit. 'Lotus') or Kamala (Sanskrit: कमल, lit. 'Lotus'), sacred lotus, pink lotus, Indian lotus, or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. It is sometimes colloquially called a water lily, though this more often refers to members of the family Nymphaeaceae. The lotus belongs in the order Proteales.

Lotus plants are adapted to grow in the flood plains of slow-moving rivers and delta areas. Stands of lotus drop hundreds of thousands of seeds every year to the bottom of the pond. While some sprout immediately and most are eaten by wildlife, the remaining seeds can remain dormant for an extensive period of time as the pond silts in and dries out. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. It is cultivated in nutrient-rich, loamy, and often flooded soils, requiring warm temperatures and specific planting depths, with propagation via rhizomes, seeds, or tissue culture, and is harvested by hand or machine for stolons, flowers, seeds, and rhizomes over several months depending on climate and variety.

Substrate is the earthy material that forms or collects at the bottom of an aquatic habitat. It is made of sediments that may consist of:

• Silt – A loose, granular material with mineral particles 0.5 mm or less in diameter.
• Clay – A smooth, fine-grained material made of fine particles of hydrous aluminium phyllosilicate minerals (such as kaolinite).
• Mud – A mixture of water with silt, clay, or loam.
• Sand – Mineral particles between 0.06 and 2 mm in diameter.
• Granule – Between 2 and 4 mm in diameter.
• Pebble – Between 4 – 64 mm in diameter.
• Cobble – between 6.4 and 25.6 cm in diameter
• Boulder – more than 25.6 cm in diameter.
• Other, assorted organic matter, detritus.

Stream substrate can affect the life found within the stream habitat. Muddy streams generally have more sediment in the water, reducing clarity. Clarity is one guide to stream health.

In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants.

Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula.

Mud (from Middle Low German mudde, mod(de) 'thick mud', or Middle Dutch) is loam, silt or clay mixed with water. Mud is usually formed after rainfall or near water sources. Ancient mud deposits hardened over geological time to form sedimentary rock such as shale or mudstone (generally called lutites). When geological deposits of mud are formed in estuaries, the resultant layers are termed bay muds. Mud has also been used for centuries as a construction resource for mostly houses and also used as a binder. An Old English word for it was fen, now in most dialects referring to a type of wetland.

Adobe (/əˈdoʊbi/ ə-DOH-bee; Spanish: [aˈðoβe]; via Spanish, from Arabic الطّوب (at-tūb)) is a building material made from loam and organic materials. Adobe is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world.

Adobe architecture has been dated to before 5,100 BP.

A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are black mud rivers. There are also black mud estuaries.

Blackwater rivers are lower in nutrients than whitewater rivers and have ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was first proposed by Alfred Russel Wallace in 1853 based on water colour, but the types were more clearly defined by chemistry and physics by Harald Sioli [de] from the 1950s to the 1980s. Although many Amazonian rivers fall clearly into one of these categories, others show a mix of characteristics and may vary depending on season and flood levels.
