Do metamorphic rocks have holes?
Metamorphic rocks can sometimes have spaces or voids called vesicles, but these are not common in all metamorphic rocks. Holes or voids can also form in metamorphic rocks through the dissolution of minerals or inclusions during the rock's formation process. Overall, metamorphic rocks are more likely to have a solid, dense structure compared to sedimentary rocks, which are more prone to having visible pores or holes.
What b do minerals sometimes form in metamorphic rock?
Minerals in metamorphic rocks can form due to changes in temperature and pressure, which cause existing minerals to recrystallize or new minerals to grow. The specific minerals formed depend on the original composition of the rock and the conditions under which the metamorphic process occurred.
What type of rocks are created from large amounts of heat and pressure?
Metamorphic rocks are created from large amounts of heat and pressure acting on existing rocks. This process causes the minerals in the rock to recrystallize without melting, resulting in a new texture and sometimes a new mineral composition. Examples of metamorphic rocks include marble, slate, and gneiss.
Why geologists are interested in outcrops or cliffs?
Geologists would be interested in outcrops and/or cliffs because sometimes cliffs show the different beds of rock under the Earth's surface. This is easier than drilling into the ground and getting a sample of the rocks.
What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?
Parallel alignment of minerals in metamorphic rocks typically forms under high temperature and pressure conditions. This alignment occurs when minerals recrystallize and orient themselves in a preferred direction due to the stress applied during metamorphism. This process is known as foliation and results in the development of distinct parallel layers or bands of minerals within the rock.
What rock is formed when limestone is transformed to a metamorphic rock?
Marble, or sometimes schist.
Do metamorphic rocks look like the preexisting rock from which they form?
Sometimes, but not always!
Phenomenon is sometimes referred to as the southern lights?
Aurora australis
What is the foreign plural of phenomenon?
The plural of phenomenon is phenomena.Phenomena is the usual plural of phenomenon. Phenomenons can sometimes be used as well in nonscientific writing when the meaning is "extraordinary things, occurrences, or persons".
Why is coal still a rock?
It is a metamorphic rock . Also the coal is sometimes considered a sedimentary rock.
What do minerals sometimes form in metamorphic rocks?
They form when layers of minerals lay on top of each other
Metamorphic rock?
This rock has been through a lot man. Mad pressure on it and sometimes heat too
When you close your eyes you sometimes see a white kidney shapes?
its called entoptic phenomenon

The heat and pressure at which some metamorphic rocks origanially form allow them to sometimes remain?
intact and preserve their mineral composition. This can lead to the retention of original rock features while undergoing changes in texture and structure, creating new metamorphic characteristics.
What are the sources of heat the helps the metamorphic rock to form?
Usually geothermal energy. Sometimes the heat from volcanic lava.
What B do minerals sometimes form metamorphic rocks?
They form when layers of minerals lay on top of each other
