What happen to the crust when the molten rock sink to lower mantle?

Why does cool rock materials sink when convection takes place in the mantle?
Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.
What will rise and what will sink?
a stone will sink and a feather would rise
What makes plates move-?
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.
One hypothesis states that plate movements results from convection currents in the?
Earth's mantle. These convection currents are driven by heat from the Earth's core, which causes material in the mantle to become less dense and rise, and denser material to sink. This movement of the mantle material pushes and drags the tectonic plates along with it.
What will happen to the convection currents in the mantle if earth's interior cools down?
Convection currents are transferring heat to the surface through the movement of mantle rock. If the interior of the planet cools, the mantle rock would be too solid to move, and there would be no heat to transfer.
Why does magma rise toward the crust and not sink into the mantle?
By being less dense than, so slightly buoyant in, the surrounding rock.

When rock cools it becomes more dense and becomes to?
sink below the surface.
When rock cools it becomes more dense and trends to?
sink below the surface.
When rock cools it becomes more dense it tends to?
sink below the surface
Why does the earth interior is moving?
First, because the core is mainly liquid and the Earth is rotating. Second, The Earth get a little tug from the moon.

Where does Cooler older oceanic lithosphere sink?
Down into the mantle. At a depth of about 600 miles they become undetectable seismographicaly and are believed to have melted back into the mantle rock.
If the layers of rock sink to the Earth's mantle as a result of the sliding plates what will the fossils most likely experience?
they will be destroyed.
