Salinity vs. depth profiles are different in different parts of the ocean, so there is really no one correct answer to this question.
The top most layer has more salinity. But ignoring thermo-haline currents.
The top layer of the Earth is called the crust. It is a solid, rocky outer shell that varies in thickness beneath the continents and oceans.
Because of the solidification of the water under low temperatures. The water is "turned" into ice, leaving the salt behind. So the salt is left in the water, with the freshwater turned into ice floating on top. If the glaciers melt, the salinity will decline, because this new freshwater will dilute the salty waters.
the most dense part of the water is in the pacific ocean. it is located near the middle of the ocean. go 50 miles past the middle and you there. Make sure you go north though. It's an ocean trench. HOPE THIS HELPS>>>>>EVEN THOUGH IS'T WRONG...
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
The higher the saline content in water the heavier the water. This causes it to sink towards the bottom and water with lower levels will rise to the top. It will remain so unless stirred vigoriouly and often. Many animals live, and thrive in this setting, such as salt marshes, springs, also some ponds and lakes.
No, the organic layer is not always on top of the aqueous layer. The layering depends on the relative densities of the organic and aqueous phases. The less dense layer will be on top.
Dissolving salts in water increases the density slightly. Ocean waters have an average density about 2.5% greater than fresh water. The Dead Sea has a much higher density, somewhere roughly near 20% greater than fresh water due to its 30% salinity level.
The top layer of soil is the most fertile layer. It is the best for growing crops.
That would be the 2nd layer, the stratosphere layer with the ozone at top.
The skin layers from top to bottom are the epidermis (top layer), dermis (middle layer), and hypodermis (bottom layer).
In sedimentation, the layers are arranged in chronological order with the oldest layer at the bottom and the youngest layer at the top. This is known as the Law of Superposition in geology, which helps scientists determine the relative ages of different rock layers.
