What else can I help you with?
Do all metamorphic rocks have layers?
No. The layering or foliation only occurs when there is a variation in the composition of the original rock. If the rock is homogeneous, then there will be no foliation.
Which statement is true about a metamorphic rock that was exposed to stress equally from all directions?
If the rock was exposed to pressure equally from all directions, then it will likely not show foliation
What can rock foliation tell us?
Rock foliation is the result of pressure and recrystallization when rocks undergo metamorphosis. It is the layering and parallel alignment of flattened or directionally oriented mineral crystals. Slate, phyllite, schist, and gneiss are all metamorphic rocks with foliated texture.
Can all rocks change into metamorphic rocks?
no
How do metamorphic rocks layer?
a metamorphic rock is a rock that has been changed from one rock to another by heat and/or pressure.....they amount of layers would depend on what kind of rock.....all rocks have a different amount of layers sorry

Why don't all rocks have foliation?
Not all rocks exhibit foliation because foliation is primarily a characteristic of metamorphic rocks that have been subjected to directed pressure and temperature, causing minerals to realign into parallel layers. Igneous rocks, which form from the cooling of molten material, and sedimentary rocks, which are formed from the accumulation and lithification of sediments, generally lack this layered structure. Additionally, the specific mineral composition and the conditions of formation play a crucial role in whether foliation develops. Consequently, only certain metamorphic environments and rock types will display foliation.

How does metamorphic rock and sedimentary rocks differ in their process of formation?
Sedimentory rocks form in several stages, which are: weathering, errosion, sedimentation, cementation and at the end lithification. In case of formation of metamorphic rocks, rock of any origin altered in mineralogical composition, chemical composition, or structure by heat, pressure, and movement. Nearly all such rocks are crystalline.
Can all rocks change into metamorphic rocks?
no
Can metamorphic rocks form form other metamorphic rocks?
yes, all rocks can form from all others depending on pressure, etc

Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What are two examples of Metomorphic rocks?
Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
What kind of rocks can produce metamorphic rocks?
All sedimentary and igneous rocks
What are the engineering considerations for igneous sedimentary and metamorphic rocks?
For igneous rocks, engineering considerations include their durability, strength, and resistance to weathering. Sedimentary rocks need to be evaluated for their porosity, permeability, and compaction characteristics. Metamorphic rocks require assessment of their foliation, texture, and potential for deformation under stress. Additionally, all three types of rocks must be studied for potential environmental impacts, such as leaching of harmful minerals.
