A marine transgression is a geologic event where sea level rises relative to the land and the shoreline moves toward higher ground, resulting in flooding. Transgressions can be caused by the land sinking or by the ocean basins filling with water or decreasing in capacity.
During the Permian-Triassic extinction, the largest extinction event in the Earth's history, the global sea level fell 250 m (820 ft). [ 3 ] A major regression could cause marine organisms in shallow seas to go extinct, but mass extinctions tend to involve both terrestrial and aquatic species, and it is harder to see how a marine regression ...
However, the sea wall did not offer much help: buildings continued to be affected by the erosion. Then a storm came and broke the sea wall, it then flooded the land behind it. These events cause many land investors to back out. Eventually, Hampton-on-Sea had to be abandoned because the erosion overtook so much of the land.
Events such as earthquakes or volcanic eruptions may cause land subsidence therefore causing isostatic sea level increases. [2] Eustatic sea level rise can also be caused by many reasons. One common reason is thermal expansion. [2] Thermal expansion occurs when water gets warmer and so the volume of water increases, this therefore causes global ...
The Ghyben–Herzberg ratio states that, for every meter of fresh water in an unconfined aquifer above sea level, there will be forty meters of fresh water in the aquifer below sea level. In the 20th century the vastly increased computing power available allowed the use of numerical methods (usually finite differences or finite elements ) that ...
Officials are investigating a possible outbreak of Legionnaires’ disease at a Florida elementary school after a kindergarten teacher died. Katherine Pennington, 61, died on Nov. 24 after testing ...
Long-lasting toxins known as ‘forever chemicals’ have been found in samples of drinking water from across the world, a new study reveals (Getty)
If the soil is saturated by water, a condition that often exists when the soil is below the water table or sea level, then water fills the gaps between soil grains ('pore spaces'). In response to soil compressing, the pore water pressure increases and the water attempts to flow out from the soil to zones of low pressure (usually upward towards ...
