Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms. It occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as ...
Tafoni often occur in groups that can riddle a hillside, cliff, or other rock formation. They typically develop in siliceous, either coarse-grained (sandstone) or coarsely crystalline (granite), rock types. They also have been observed in lacustrine silts, tuffs, and conglomerates. They can be found in all climate types, but are most prolific ...
Honeycomb weathering, also known as honeycombs, honeycombed sandstone, is a form of cavernous weathering that consists of regular, tightly adjoining, and commonly patterned cavities that are developed in weathered bedrock; are less than 2 cm (0.79 in) in size; and resemble a honeycombed structure. Honeycombs also been called alveoli, lacework ...
Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes, such as frost shattering, frost wedging, and cryofracturing. The process may act on a wide range of spatial and temporal scales, from ...
Halophyte. Spartina alterniflora (cordgrass), a halophyte. A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ...
To minimize salt damage to plants and water, try using anti-skid products, such as sand, instead of salt when possible. Calcium chloride, potassium chloride, and magnesium chloride de-icers are ...
The Southern North Sea basin is the largest gas producing basin in the UK continental shelf, with production coming from the lower Permian sandstones which are sealed by the upper Zechstein salt. [1] The evolution of the North Sea basin occurred through multiple stages throughout the geologic timeline. First the creation of the Sub-Cambrian ...
Soda inermis, the opposite-leaved saltwort, oppositeleaf Russian thistle, or barilla plant, is a small (to 0.7 m tall), annual, succulent shrub that is native to the Mediterranean Basin. [1][2] It is a halophyte (a salt-tolerant plant) that typically grows in coastal regions and can be irrigated with salt water.
