Oceans and Seas

A feature associated with the Challenger Deep

A large section of the ocean mostly surrounded by land or islands

Pelagic animals, many using bioluminescence, are the only living things here

Essential for echolocation

Process of removing the chemicals in the ocean water to make it suitable for drinking

Water that is saltier than the average 3.5% salinity

Measure of the ocean's saltiness

Changes with seasons to form a thermal layer

An underwater feature that forms at the margins of divergent tectonic plates

The only substance dissolved in seawater is salt.

Can reach up to 1100 atm in the Challenher Deep

Sea level is the same elevation everywhere on earth.

No light from the surface reaches this point

The ocean's saltiness

Sea ice is just as salty as the surrounding water.

Bottom dwelling organisms are called benthic organisms.

Covers 71% of the earths surface

The area of the open ocean that has relatively constant salinity and good water clarity

A feature carved into the continental shelf; likely remnant of the Flood

Marine organisms here must be mobile or have sturdy design and good grip on surfaces.

1.028g/cm³ at normal conditions

The correct name for a submerged volcano

The area of the ocean above the continental shelf is similar to shallow areas near land.

Low salinity water

The Challenger Deep is deeper than the tallest mountain in the world is tall.

Lowered by increasing water's saltiness
