The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [2] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation.
The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
In some cases, a lava plateau may be part of a single volcano. An example is the massive Level Mountain shield volcano in northern British Columbia , Canada , which covers an area of 1,800 km 2 (690 sq mi) and a volume of 860 km 3 (210 cu mi).
It contains dissected lava plains, rolling hills, alluvial fans, valleys, and scattered mountain ranges in the northern part of the Great Basin. Although arid, the ecoregion is higher and cooler than the Snake River Plain to the north and has more available moisture and a cooler climate than the Central Basin and Range to the south.
Lava lake – Molten lava contained in a volcanic crater; Lava field, also known as lava plain – Large, mostly flat area of lava flows; Lava spine – Vertical growth of solid volcanic lava; Lava tube – Natural conduit through which lava flows beneath the solid surface; Lavaka – Type of gully, formed via groundwater sapping
In the foreground, long lava flows are visible. The surface of Venus is dominated by volcanic features and has more volcanoes than any other planet in the Solar System. It has a surface that is 90% basalt, and about 65% of the planet consists of a mosaic of volcanic lava plains, indicating that volcanism played a major role in shaping its ...
Plains can be formed from flowing lava; from deposition of sediment by water, ice, or wind; or formed by erosion by the agents from hills or mountains. Biomes on plains include grassland (temperate or subtropical), steppe , savannah or tundra . In a few instances, deserts and rainforests may also be considered plains. [4]
