Which statement describes the best way to prepare a microscope for safe transport back to a storage area? put a cover over the microscope. set the microscope to the high-power objective position. wrap the electrical cord around the arm of the microscope. raise the stage of the microscope until it touches the objective.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
