Salt marsh – Coastal ecosystem between land and open saltwater that is regularly flooded; Sea cave – Cave formed by the wave action of the sea and located along present or former coastlines; Seamount – Mountain rising from the ocean seafloor that does not reach to the water's surface
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Rio Grande Gorge Bridge. Geologically, the Rio Grande Gorge is a canyon, [1] carved out by erosion over the last several million years. [2] The Rio Grande Gorge and its river follow a topographical low within the larger Rio Grande Rift; a mixture of volcanic activity, shifting tectonic plates, and erosion of layers of gravels and lava yielded the recognizable narrow, deep gorge visible today.
The gorge has a unique ecosystem with species of animals and plants barely explored and affected by human influence. Its climate ranges from subtropical to Arctic, and it has several different vegetation zones: Lowland tropical forests, including the tropical rainforest and seasonal tropical forests; tropical montane and subtropical broad-leaved forest; subalpine temperate coniferous forest ...
Niagara Gorge is an 11 km (6.8 mi) long canyon carved by the Niagara River along the Canada–United States border, between the U.S. state of New York and the Canadian province of Ontario. [1] It begins at the base of Niagara Falls and ends downriver at the edge of the geological formation known as the Niagara Escarpment near Queenston, Ontario ...
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.
Along their journey, they carry essential nutrients for the ecosystem in the form of sediment. Image credits: Siena International Photo Awards #19 The Beauty Of Nature, Honorable Mention: Electric ...
Invoking images of the open ocean's surface, the imagination can conjure up an endless empty space. A flat line parting the blue below from the blue above. But in reality a diverse array of species occupy this unique boundary layer. A tangle of terms exist for different organisms occupying different niches of the ocean's surface.
