Do plates become more dense or less dense when they become cooler?

Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.

What happens when oceanic plates meet?
If the plates are moving toward each other from opposite directions, the more dense oceanic plate will subduct in a conveyor belt like operation under the less dense continental plate. Transform plate boundaries occur where plates of any combination grind alongside each other and result in faults and earthquakes.
Why do tectonic plates float on the atmosphere?
They don't. Tectonic plates float on the asthenosphere, as they are a bit less dense.
What process occurs in the hot pliable mantle rock beneath the earths plates?
Convection. The same as the shimmering above a hot road in summer, heated material is less dense and rises over cooler material.convection currents
Are rocks changed by metamorphism less dense?
That depends on the rock and the type of metamorphism is underwent. Some rocks become more dense, some become less.
Can you describe the density changes between the two substances that a lava lamp contains?
The light at the bottom heats up the oil, therefore expanding it and making it less dense. The less dense oil then floats to the top, where the cooler, more dense, oil floats to the bottom.
What is true awarm is less dense than cooler air bwarm air is as dense as cooler air cwarm air has no density dwarm air denser than cool air?
Warm air is less dense than cooler air.
Why does plates sometime sink into the mantle?
Because a "lighter" (less dense) plate floats above it. Note; continental plates are less dense than seabed.
Why do the plates float on the mantle?
Tectonic plates float on the mantle because they are less dense

What is the difference between oceanic and continental plates?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
Why is an oceanic plate always subducted but not a continental plate?
Continental plates are lighter (less dense) than oceanic plates.

If the mass of a fixed volume of air increases does the density become more or less dense?

Would the density in liquid become more dense or less dense when thermal energy is added?

Is cooler air less dense than warm air?
yes i hope this helps :D
