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 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
Why is water located above the earths crust but below the air?
Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
When convection takes place in the matle why does cooler material sink while warmer material rises?
Cooler material (magma) shrinks and becomes more dense. Gravity acts on this denser material more strongly because of its greater unit mass (density = Mass/volume). Lighter material rises as the heavier material displaces it below. This produces a the apparent bouyant force.
How does the temperature and density drive the convection currents in the mantle?
Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
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.
Why are cooler particuls pulled down by gravity?
cooler particles are slower moving thus more dense. the more dense the material the further it will sink
In which situation would the angle of refraction bend toward the normal?
When moving from a denser material to a less dense material.

Why does magma flow upward toward the earths surface?
Convection. Hotter equals rarer, colder equals denser. So the warmer material in the lower mantle and outer core rises through the cooler material in the outer mantle toward the crust, while the cooler material falls towards the core. They then cool and heat up respectively, and change positions. They then cycle around heating and cooling, rising and falling.
Why is water located above the earths crust but below the air?
Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
Why do less dense compounds make up earths crust while the densest compound make up the earths core?
because the heavier elements are pulled toward center of the earth by gravity
Is cooler air more dense?
yeh, cooler air is more dense. that's the reason for fog and rain.

Do convection currents form in the mantle when heated materials become more dense?
Yes, convection currents form in the mantle due to the heating and cooling of material, which causes density differences and drives the movement of material. When material in the mantle is heated, it becomes less dense and rises, while cooler, denser material sinks, creating a circulation pattern known as mantle convection.
How does the temperature and density drive the convection currents in the mantle?
Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
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.
