Yes, more dense (colder water) sinks below less dense (warmer) water. That is the reason for the Thermocline.
^^^^^^
A widespread permanent thermocline exists beneath the relatively warm, well-mixed surface layer, from depths of about 200 m (660 feet) to about 1,000 m (3,000 feet), in which interval temperatures diminish steadily. The deep waters below the thermocline layer decrease in temperature much more gradually toward the seafloor. In latitudes marked by distinct seasons, a seasonal thermocline at much shallower depths forms during the summer as a result of solar heating, and it is destroyed by diminished insolation and increased surface turbulence during the winter. Water density is governed by temperature and salinity; consequently, the thermocline coincides generally with the pycnocline, or layer in which density increases rapidly with depth. The middle layer of water in a lake or reservoir during the summer is also called a thermocline.

What else can I help you with?
If an object floats does that mean it is dence?
If an object floats it is less dense than the substance it's floating in.
Is ice or water less dence?
Ice is less dense than water. When water freezes into ice, the molecules arrange themselves in a pattern that makes ice less compact, causing it to take up more space and be less dense than liquid water.
How can you determine weather a solid substance is more dense or less dence than water?
You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance is less dense.
Is polystyrene less dence than water?
yes polystyrene is ls less dence than water because it floats
How can you determine whether a solid substance is more dense or less dense than water?
see if it floats, if it floats it is less dense.
How does ice floats on water?
It is less dense than water, therefore it floats on water.
Is a rubber ducky more dense then water?
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
Why does a raft floats in water?
it is less dense
When a ice cube floats i water they are less what?
Less dense
Is ice as dense as water?
Ice is less dense than water, that's why it floats.
How do you know when a solid is less dense then water?
When it floats in water.
Does thinks sink if its less dence that water?
No, an object will float if it is less dense than water. If an object is less dense than water, it will displace an amount of water equal to its weight, causing it to float.
