Marble is a metamorphic rock that was originally?
By definition a metamorphic rock has undergone recrystallization without melting - that requires a lot of heat and pressure. Marble is a metamorphic rock - it is recrystallized limestone or dolostone.
Is it physical or chemical when dry ice evaporates without melting as time passes?
It is a physical change because the composition of the dry ice didn't change; it just changed forms
How are melting and freezing alike?
they are both forms of tempurature
What rock forms by pressure on large masses of rock?
Metamorphic rock forms when under lots of pressure.
Which process is always required before igneous rock forms?
Melting-solidification.
A metamorphic rock is from where?
Metamorphic rock usually forms when a rock is altered under heat and pressure without melting. Some rocks may be metamorphosed by contact with hot water,
Why is there a difference between rocks?
The difference lies in the method of the rock's creation (melting, sediment, pressure), and the elements available when and where it forms.
The melting of metamorphic or igneous rock forms what substance?
The melting of metamorphic or igneous rock forms magma.
What forms when high temperatures and pressures combine to alter mineralogy or chemical composition of a rock without melting it?
metamorphic rocks
What forms when a high temperatures and pressures combine to alter the texture mineralogy or chemical composition of a rock without melting it?
metamorphisis
Why doesn't the earth's iron core melt?
the earth has plates because it forms nature
What rock forms near earth's surface without influence of heat and pressure?
Sedimentary.

Melting and calving are two forms of ablation?
True
When magma forms within the mantle it is most often a result of?
Either the loss of confining pressure causing the melting point of the material to drop below the in-situ temperature or due to the presence of volatiles which enter the mantle where subduction occurs and also lower the melting point of the material.
What process forms and valleys?
Glaciers, mostly Glaciers Melting
