Definition: A tidal water channel. Creeks may often dry to a muddy channel with little or no flow at low tide, but often with significant depth of water at high tide.
Definition: The marine hydrothermal vent biome comprises regions of the marine benthic biome where heat generated due to tectonic activity, either at divergent plate boundaries or convergent ocean plates where back-arc spreading occurs, is released or 'vented' to the surface. The resultant high temperature water jets are laden with dissolved metals and minerals.
