What is the rapid change in salinity as you go deeper in the ocean called?
What is the rapid change in salinity as you go deeper in the ocean called?
pycnocline
What is the thermocline layer?
A thermocline is the transition layer between warmer mixed water at the ocean’s surface and cooler deep water below. Below 3,300 feet to a depth of about 13,100 feet , water temperature remains constant.
Why is the mixed layer deepest in winter?
During early winter, the atmosphere cools the surface and strong wind and negative buoyancy forcing mixes temperature to a deep layer. The deep temperature layer along with strong stratification in the salinity gives the conditions for barrier layer formation.
What best describes a thermocline?
A thermocline is an area where the temperature of the ocean sharply decreases. Explanation: The thermocline is the indication of a transition between two layers of water with different temperatures and densities, for example in lakes or oceans.
What are the 3 temperature zones in the ocean?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.
What is the deepest marine zone?
hadalpelagic zone
What are the five zones?
The earth is divided into five distinct zones based on their climatic conditions, known as geographical zones. These zones are the North Frigid Zone, the North Temperate Zone, the Tropics, the South Frigid Zone, and the South Temperate Zone.
What are the layers of the sea?
Our Layered Ocean. There are three main ‘layers’ to the ocean that we will focus on: the surface ocean, the deep ocean, and the seafloor sediments (sediments that are still in contact with seawater). Each plays a vastly important role in the absorption of carbon dioxide from the atmosphere, and in ocean circulation.
