No. Molten rock expands due to heat as the molecules get excited, therefore it is less dense than solid rock.

Is molten rock heavy?

Yes. It is about as dense as solid rock.


Is liquid magma less dense or more dense?

Liquid magma is less dense than solid rock because it is a molten mixture of rock, minerals, and gases. When magma rises to the Earth's surface and cools, it solidifies into igneous rock.


When rock heats up and becomes molten rock does it sink closer to the core?

No, molten rock is less dense than solid rock and rises through the crust.


Why does molted rock rise then sink?

Molten rock, or magma, rises because it is less dense than the surrounding solid rock. As it moves upward, it can cool and solidify, becoming more dense and sinking back down. This process of rise and sink is driven by the differences in density between the molten rock and the surrounding rock.


What is more dense rock or solid?

It depends on the particular rock and on the particular solid. Please restate the question, giving more specifics, such as what rock and what solid.


What is the difference between solid rock and molten rock?

Heat! One has more [molten] while the other has less [solid]. Heat is also known as Kinetic Energy: the Energy of Motion.


Is magma more dense then rock?

No. Magma varies in density, but it will be less dense than a solid rock of the same composition.


Is the lithosphere solid or liquid rock?

The Lithosphere is solid rock floating on molten rock.


Is gas more dense then rock?

rock is denser than gas because it is a solid


Cooler molten rock does what sink or rise?

Cooler molten rock sinks because it is denser than the hotter, less dense molten rock around it. As it cools, it becomes more rigid and eventually solidifies, creating new layers of rock over time.
