Indian ocean
a measure of the amount of dissolved salts in a given amount of liquid
Salinity
The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters
surface zone
a steep temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temperatures.

Thermocline
Life in the deep sea must withstand total darkness, extreme cold,and great pressure. Deep Zone Ocean-The deep zone ocean is a zone of the world’s oceans occupying intermediate position between the abyssalpolegic region and the sea bed
deep zone
the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
water cycle
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase
Evaporation
water which collects as droplets on a cold surface when humid air is in contact with it
Condensation
rain, snow, sleet, or hail that falls to the ground
Precipitation
the action or process of precipitating a substance from a solution.
continental shelf
the slope between the outer edge of the continental shelf and the deep ocean floor.
continental slope
The continental rise is an underwater feature found between the continental slope and the abyssal plain. This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean.

Image result for abyssal plain
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface
abyssal plain
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary
mid-ocean ridge
a large elongated depression with steep walls formed by the downward displacement of a block of the earth’s surface between nearly parallel faults or fault systems.
rift valley
a submarine mountain
Seamount
Oceanic trenches are topographic depressions of the sea floor, relatively narrow in width, but very long. These oceanographic features are the deepest parts of the ocean floor.
ocean trench
the small and microscopic organisms drifting or floating in the sea or fresh water, consisting chiefly of diatoms, protozoans, small crustaceans, and the eggs and larval stages of larger animals. Many animals are adapted to feed on plankton, especially by filtering the water.
Plankton
aquatic animals that are able to swim and move independently of water currents.
Nekton
the flora and fauna found on the bottom, or in the bottom sediments, of a sea, lake, or other body of water.
Benthos
Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture.
