What is the process where cool dense material sinks and warm bouyant material rises?
Convection, hope this helps.
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.
What is the motion created when heated material continually rises cools and sinks?
A convection current is created when a heated material continually rises, cools and sinks. Plate tectonics are driven by this type of motion,
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 are two models proposed for how convection moves plates?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Convection occurs because heated material becomes what?
Convection occurs because heated material becomes less dense and rises, while cooler, denser material sinks. This creates a circular motion of fluid or air to transfer heat.
What direction do convection currents move?
Warmer material in a convection current rises upwards.
What is the transfer of heat when warm material rises and cold sinks?
This is called convection.
The motion created when heated material continually rises cools and sinks?
Convection current
What causes the earth plate to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.

When the hotter part of the liquid rises and the cooler liquid moves into its place what is this called?
Convection
What caused the plates to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.
