A combination of increased temperature, a decrease in confining pressure or addition of volatiles can all act to cause rock to melt.
Yes, a rock can change. It's not as easy to change a rock as it is to change a marshmallow, but it can be done.
It would first change from a solid to a liquid.
lava cooling to become rock is a change of state from liquid to solid
Melting the rock to its liquid form then re-freezing it into a solid will realign the rock's crystaline structure thereby altering the density.
This process is called solidification or freezing. When a substance loses heat energy and its particles slow down enough to form a rigid structure, it changes from a liquid to a solid state.
change of a liquid to a solid
The change from liquid to solid is called freezing.
1. Earth (the material) is a solid. 2. Earth (the planet) is a solid with a liquid center.
Sure, change from solid to liquid is a physical change
Solid rock.
The Lithosphere is solid rock floating on molten rock.
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
