WebWhat major types of organisms live in the top, middle and bottom layers of aquatic life zones? -Euphoric Zone:Brightly lit zone, phytoplankton carryout photosynthesis -Swordfish, sharks, bluefin tuna -Upwellings:Carry water and nutrients up from below -Bathyal Zone: Dimly lit middle zone, little sunlight -zooplankton and smaller fish WebThe epilimnion or surface layer is the top-most layer in a thermally stratified lake. The epilimnion is the layer that is most affected by sunlight, its thermal energy heating the surface, thereby making it warmer and less dense. As a result, the epilimnion sits above the deeper metalimnion and hypolimnion, which are colder and denser. [1]

WebThe layers of the pelagic zone. All but the epipelagic zone make up the aphotic zone. Zones of the water column as defined by the amount of light penetration. The mesopelagic is sometimes referred to as the dysphotic zone. In the ocean, the aphotic zone is sometimes referred to as the dark ocean. WebThere are three types of beds that make up a delta (Figure 10.6). The first particles to be dropped off are the coarsest sediments and these form sloped layers called foreset beds that make up the front edge of the delta. Further out into calmer water, lighter, more fine grained sediments form thin, horizontal layers. These are called bottomset ...
