Abiotic Factors Of The Ocean Floor

Minerals from the smokers.

Abiotic factors of the ocean floor.

The limiting factor in an ecosystem can change but only one factor is in effect at a time. Along mid ocean ridges where tectonic plates spread apart magma rises and cools to form new crust and volcanic mountain chains. The water that comes out of the chimneys is rich in dissolved minerals from the crust mostly sulfides. Saltier water is more dense.

Pelagic sediment is composed of shells animal skeletons decaying microorganisms and plants. Salts come from land via rivers where it concentrates as ocean water evaporates.

Within the pelagic realm is the photic zone which is the portion of the ocean that light can penetrate approximately 200 m or 650 ft. Ocean abiotic factors continued tides are the periodic short term changes in the height of the ocean surface at a particular place. Seawater circulates deep in the ocean s crust and becomes super heated by hot magma. The growth of plants on the forest floor is limited by light availability.

Tides are caused by the interaction of gravitational forces of the sun and moon and the rotation of the earth. Hydrothermal vents are like geysers or hot springs on the ocean floor. Both biotic and abiotic factors affect local ecosystems but the biotic factors are often determined first by the abiotic factors. Most parts of the ocean experience two high tides and two low tides daily.

Abiotic factors are non living factors in an ecosystem freshwater is any body of water on the earth s surface with low salinity 1000 mg or less of dissolved salt per liter of water. These one to three foot high smokers emit a substance that looks much like smoke. The abiotic or non living factors influencing the world s oceans include temperature sunlight wind and dissolved minerals. Abiotic factors the deepest place in the world soil type the mariana trench is the deepest part of the world at 10 994 meters deep.

These bodies of water include lakes bogs swamps underground water and rivers. The ocean floor at such depth consists of pelagic sediment also known as biogenous ooze. Ecosystems biotic abiotic factors and the carbon water cycles duration. Abiotic factors influencing aquatic biomes.

The open ocean has an average salinity level of 35 parts salt per thousand and an average ph of 8 1. The temperatures in lakes vary with depth and location on earth. A limiting factor may be biotic or abiotic. Abiotic factors biotic factors food web human influence chimneys.

It is generally yellowish. Salinity affects water density. An example of a limiting factor is the amount of sunlight in a rainforest.
