3. Pressures and Mechanical Stress
Two plates collide; great temperatures
and pressures can be produced.
Metamorphic rocks form along the
margins of continents, where plates
carrying continental crust collide with
plates carrying oceanic crust.
plate collisions can cause new mountain
ranges to form.
4. Great
Temperatures
- Metamorphic rock
can also result when hot,
molten rock called
magma is forced up
through existing rocks in
the crust, heating the
rocks and increasing the
pressure.
Insane
- layers of overlying
rocks put huge pressure
on them to turn to
metamorphic rock.
