In geology, a fissure is a fracture or crack in rock along which there is a distinct human courage captured by the acclaimed filmmakers of National Geographic A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity.The vent is often a few metres wide and may be many kilometres long. Fissure vents can cause large flood basalts which run first in lava channels and later in lava tubes.After some time the eruption builds up spatter. . Isolated blocks of fine-grain sidewall material occur in the central portion of the fissure. The road building team mitigated the fissure by deploying a geosynthetic liner to isolate the fissure. Cost of mitigation was ~ $200,000
An ocean vent sits over a deep fissure in the ocean floor. Ocean vents eject hot, often toxic, fluid s and gas es into the surrounding seawater. They often mark sites of tectonic activity, and create some of the most hostile habitats on Earth. Ocean vents are a type of hydrothermal vent Fissure In geology, a fissureis a fracture or crack in rock along which there is a distinct separation; fissuresare often filled with mineral-bearing materials.

When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure.

Experts on the meaning behind Biden's statement on the Armenian genocide A dike or dyke, in geological usage, is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack
