Clines of Ocean

What is the definition of thermocline?

• A thermocline is a distinct layer in a large body of water where the temperature changes rapidly with depth.

• A thermocline is a measurement of the salinity of a body of water.

• A thermocline is a type of fish that lives in deep ocean waters.

• A thermocline is a layer of ice that forms on the surface of a body of water.

What are the factors that affect thermocline?

• wind speed, water depth, and sunlight intensity

• water pressure, wave height, and current speed

• temperature, salinity, and density of the water

• oxygen concentration, pH level, and turbidity

What is halocline?

• A layer of water in which the salinity changes rapidly with depth.

• A layer of water in which the temperature changes rapidly with depth.

• A layer of water in which the pressure changes rapidly with depth.

• A layer of water in which the oxygen concentration changes rapidly with depth.

What is pycnocline?

• A layer in a body of water where there is a rapid change in temperature with depth.

• A layer in a body of water where there is a rapid change in pressure with depth.

• A layer in a body of water where there is a rapid change in salinity with depth.

• A layer in a body of water where there is a rapid change in density with depth.
