What zone is most marine life found in?

What is the ocean floor like?

a bathymetric technique that differentiates between multiple layers of the ocean bottom

The region submarine canyons are usually found

The environment marine organisms that are euryhaline would most likely be found-

True or False
temperature is a significant life-limiting factor in the ocean depths

describes the pelagic zone

the zone that has warm waters, rich in marine life

the depth that light stops penetrating the ocean

the body shape or adaptation that is best suited for life in the pelagic zone

the habitat that has a water level that changes with the tide

the environment where animals with chemosynthetic bacteria embedded in their tissues would most likely be found

the region where the majority of all resources are

one of the most common resources that is extracted from the ocean

technology that is useful for locating schools of commercial fish

the seafloor and its inhabitants

the area that is above water at low tide and under water at high tide
(land between high and low tides)

salinity

plains on the deep ocean floor
(is dark and unchanging)

0 - 200 m deep (in the ocean)

all open water of the ocean

The three oceanic zones

where temperature and sunlight don't change often

areas along the mid-oceanic ridges where water gets superheated from magma below and escapes into the ocean waters.

a compound consisting of a lattice (or "cage") of water molecules with gas molecules occupying holes or cavities in the lattice

the removal of salt from seawater
