When there is no weathering. When there there are no intrusions of magma beneath rock no metamorphic rock will form. But, this is impossible as the Earth atmosphere and interior forces are so dynamic. Over time all rocks will undergo some kind of change.

Are sedimentary rocks form from rock and mineral fragments and metamorphic rocks form from existing rocks?
Yes sedimentary rocks form from erosion, consolidation, and cementation of old rocks. Metamorphic rocks form from changes to an existing rock through a mineralogical change within brought on primarily by heat and to some extent by pressure.
What existing rock can change into another type of rock when it is subjected to great?
when it is subject to great pressure
How rocks change form is known as the what?
how rocks change form is the rock cycle.
What m described rocks that were formed when existing rocks were heated or squashed?
Metamorphic rock. This can naturally form an existing Sedimentary, Igneous or Metamorphic rock due to exposure to heat and/or pressure.
What is a rock formed when high heat and great pressure change existing rocks?
Metamorphic
Does chemical process change he form of existing rock?
yes
What are metamorhpic rocks?
Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means "change in form".
What changes the form of existing rock?
METAMORPHISM.

What rocks form from existing rocks?
metamorphic rock
What existing rock can change into another type of rock when it is subject to great?
Heat.
What are mettamorphic rock?
A metamorphic rock is a rock that is changed from an already existing form of rock by pressure or temperature
What rock families can form magma if hot enough?
All the three existing rock families/types/classes (ie, igneous, sedimentary and metamorphic rocks) can form magma, if they become hot enough to melt and change to molten form.
Which rocks could form when existing bits of rock stick together?
If existing bits of rock become attached through the process of lithification, a clastic sedimentary rock is formed.
What existing rock can change into another type of rock when it is subjected to great?
when it is subject to great pressure
What rocks form if bits of existing rock got stuck together?
morpheus rock is formed i think
When existing rock is subjected to high temperature and pressure form?
metmorphic rack
