Metamorphic rocks can undergo further metamorphism through additional heat and pressure. They can also be melted, then cooled, and become igneous rock. They can also erode and become components of sedimentary rocks.

Which rock cannot be metamorphosed?

Rocks that are classified as non-crystalline or amorphous, such as obsidian, cannot be metamorphosed because they lack a defined crystalline structure. Metamorphism requires heat and pressure to rearrange the mineral structure of rocks, which cannot occur in amorphous materials.


Which characteristic of rocks tends to increase as the rocks are metamorphosed?

Foliation, or the alignment of mineral grains in a preferred direction, tends to increase as rocks experience metamorphism. This results in a layered appearance in metamorphic rocks, such as schist and gneiss.


Rocks being pushed together is what?

Rocks being pushed together is called compression. This can result in the rocks being folded, faulted, or metamorphosed depending on the amount of force applied.


Do the changes in rocks due to heat and pressure result in the formation of metamorphic rocks?

Yes, changes in rocks due to heat and pressure can result in the formation of metamorphic rocks. These changes can cause the minerals within the rock to recrystallize, realign, and form new mineral structures, giving rise to metamorphic rocks with distinct textures and compositions.


Why does the rock cycle have more than one path?

The rock cycle has more than one path due to the diverse geologic processes that can transform rocks from one type to another. Rocks can be metamorphosed, eroded, transported, deposited, and melted, leading to multiple pathways within the cycle. This complexity allows rocks to continually change forms over time.

What is the hardness of the Metamorphic rock?

Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.


Can metamorphic rocks be formed from other metamorphic rocks?

Yes, in a sense. Rocks can be metamorphosed multiple times, by different geologic events.


Can an igneous rock be changed?

Yes, igneous rocks can be metamorphosed or weathered and eroded.


CAN Metamorphic rocks occur from sedimentary and igneous rocks?

Yes, both sedimentary and igneous rock can be metamorphosed by heat and pressure.


What does the word metamorphic come from?

Metamorphic comes from metamorphism which is Greek for "change of form". Metamorphic rocks originate from sedimentary and igneous rocks.
