What else can I help you with?
Can crystals grow larger during metamorphism?
Yes, crystals can grow larger during metamorphism when subjected to increased temperature and pressure conditions. The atoms within the crystals have more energy to move around and rearrange, leading to their growth. This can result in larger crystal sizes and more defined crystal shapes.
What is metamorphic rock in which mineral crystals are arranged in parallel layers or band?
The metamorphic rock you are referring to is called foliated rock. Foliated rocks have mineral crystals aligned in parallel layers or bands, resulting from the re-alignment of minerals due to pressure and heat during metamorphism. Examples of foliated rocks include slate, schist, and gneiss.
Which foliate metamorphic rock has the smallest crystals?
Slate is a foliate metamorphic rock with the smallest crystals. It forms from the low-grade metamorphism of shale or mudstone, resulting in fine-grained crystals too small to be seen with the naked eye.
What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
What is porphyroblasts?
Porphyroblasts are large mineral crystals that form within a finer-grained matrix during the metamorphism of rocks. They often show a distinctive shape and can help geologists determine the pressure and temperature conditions at which the rocks formed.
Can a rock that is changed by metamorphism have crystals in parallel layers?
Yes, rocks that undergo metamorphism, especially foliated metamorphic rocks like schist and gneiss, can exhibit crystals arranged in parallel layers. This alignment is often a result of the directed pressure and temperature conditions during metamorphic processes, causing minerals to grow perpendicular to the direction of pressure, resulting in distinct layering or foliation.
Do crystals grow larger during metamorphism?
During metamorphism, crystals can grow larger through a process called recrystallization, where existing minerals rearrange their atoms to form larger crystals. This can happen due to changes in temperature, pressure, or the presence of fluids in the rock. So, yes, crystals can grow larger during metamorphism.
What are parallel lines seen on either cleavage planes or crystal faces?
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
When are two lines nonintersecting?
When two lines are parallel, then they do not intersect.
Are parallel lines actually parallel?
If they were not actually parallel then they would not be parallel lines!
Does a rectangle have parallel lines?
no parallel lines
Why does the Parthenon have no parallel lines?
it has parallel lines
What is the function of parallel lines?
parallel lines are diagonal lines or increasing lines
Does perpendicular have parallel lines?
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
What are lines that never intersect called?
the answer is parallel lines
Can parallel lines be intersecting lines?
No, parallel lines do not intersect, and never will.
What are all the lines like parallel?
parallel lines are slanted lines
