What type of sedimentary rock is made from compacted mud?
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
What can extreme pressure and temperature do to a sedimentary rock?
Turn it into metamorphic rock.
Does a rock melt when pressure increases?
No. Rock melts when temperature reaches a high enough point. Increasing pressure actually raises the temperature needed to melt rock, so it can actually cause molten rock to solidify.
What rock is formed when existing rock is altered by conditions of extreme pressure and temperature?
Metamorphic Rocks
What happens if the pressure on a rock decreases but the temperature stays the same?
nothing
How does decreasing the pressure of the rock affect the temperature at which it melts?
Decreasing the pressure on rock will allow rock to melt at lower temperature. High pressures will raise the melting point of rock.

What can extreme pressure and temperature do to a sedimentary rock?
Turn it into metamorphic rock.
What type of rock is made of previously existing rock whose formation does not involve high temperature and pressure?
Clastic sedimentary rock is a product of the weathering, erosion, and diagenesis of pre-existing rock.
Which two factors affect the temperature that rocks melt at?
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.
What are mettamorphic rock?
A metamorphic rock is a rock that is changed from an already existing form of rock by pressure or temperature
Does a rock melt when pressure increases?
No. Rock melts when temperature reaches a high enough point. Increasing pressure actually raises the temperature needed to melt rock, so it can actually cause molten rock to solidify.
Changing pressure and temperature can transform sedimentary rock into what other type of rock?
Metamorphic Rock
What happens to rock when it is exposed to very high temperature?
Rock exposed to very high temperature and pressure will soften or melt.
What changes igneous or sedimentary rock into metamorphic rock?
Heat, pressure, or transfer of elements through high temperature solutions.
Is pressure a contributor to a rock's melting temperature?
