Horizontal Zones
The first zone you encounter when coming to a beach
Supratidal Zone
The deepest zone, consisting of ocean trenches
Hadalpelagic Zone
An area where freshwater and saltwater meet
Estuary
The marine environment characterized by moving/shifting sediment
Sandy Beach
The zone that covers the entire sea floor
the benthic zone
The zone just below the low tide line.
The subtidal zone
This is also known as the twilight zone since some light penetrates, but not enough for photosynthesis.
Mesopelagic Zone
The name of the mixed salty & fresh water in an estuary
Brackish
The marine environment characterized by a hard stable substrate.
Rocky Shore
The colorful marine environment, built by animals, that occurs in warm, clear, shallow waters.
The Coral Reef
The zone that includes the ocean above the continental shelf
Neritic zone
The middle zone, with no light like the two zones below it.
Bathypelagic
An estuary characterized by low wave action, no grass, & thick mud
Mud flat
An adaptation that is useful in the Rocky Shore
Ability to cling/hold on to rocks, ability to conserve water, etc
The three zones with no light
Bathypelagic, abyssopelagic, hadalpelagic
The zone that starts after the continental shelf and reaches until another coastline.
The oceanic zone
The top zone AND the major characteristic of this zone
Epipelagic
Sunlight- enough for photosynthesis
The estuary characterized by grasses AND an adaptation these grasses can have
Salt Marsh
Resistent to salt- excrete excess salt in crystals
An adaptation useful for living in the sandy beach environment
Being able to dig into the sand, have a flattened body to withstand crashing waves, etc
Two examples of adaptations that help organisms to live in the mud flat
Mud flat- burrow, live in low oxygen areas, long beaks to feed in the mud, etc
The zone that is only submerged in water part of the time AND the name of the line that separates this zone from the zone before it.
the intertidal zone & the strand line OR high tide line
The second deepest zone- which is the deepest zone in many areas. AND one physical characteristic of this zone AND an adaptation an organism might have to live there
Abyssopelagic
Dark, lots of pressure, cold
bioluminescence, lack of eyes, large jaws/mouth
The estuary that is characterized by trees & two ways the trees are beneficial to that estuary
Mangrove Community
roots provide shelter/hiding places, protect shore from erosion by trapping sand & sediments, absorbing impacts of storms. Leaves decay and provide food for plankton.
One similarity & one difference between the Rocky Shore & Sandy beach
Both coastal
rocky is stable/ sandy sediment moves
rocky has a more vertical intertidal zone
etc
The five horizontal zones in order from beach to sea & the five vertical zones in order from top to bottom.
H: supratidal, intertidal, subtidal, neritic, oceanic
