What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?
Heat is one condition that is required to form parallel alignment of minerals sometimes found in a metamorphic rock. The other condition is pressure.
What b do minerals sometimes form in metamorphic rock?
They form when layers of minerals lay on top of each other
3 main categories of rocks?
Igneous--those that form directly from a molten state. Sedimentary--those that form from eroded particles of various sizes from other rocks. Metamorphic--igneous and sedimentary rocks, and sometimes metamorphic rocks, that undergo a transformation from heat and/or pressure.
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 is the metamorphic grade of marble?
Marble is classified as a metamorphic rock. 'Metamorphic' means that the rock has undergone a change in from. In the case of marble, it starts out as some kind of sedimentary carbonate rock (sedimentary rocks are formed by sediments and remains of plant life, etc. that have been compacted together over time) and then that rock material is transformed by a combination of heat and pressure to become marble. The changes may be a development of a chrystalline formation, or a texture or color change. Sometimes the metamorphic changes in rock may include the involvement of minerals, in additon to the heat and pressure combination. Different minerals cause the different color varieties of marble that are available.
