At one time, most people believed that the Universe was static, meaning it did not change. When larger and better telescopes were invented in the early 1900s, however, it was discovered that light from objects in space shifted toward longer wavelengths. Scientists concluded that only an expanding Universe could explain this shift. Which of the following statements is supported by this example? A. The principle of the expanding Universe is a scientific law. B. Once a scientific theory has been accepted, it can never change. C. The theory of the expanding Universe cannot change, even if new evidence arises. D. Scientific knowledge can change when new evidence or interpretations arise.

During metamorphic processes, increased pressure and temperature can affect the of minerals in rock. rocks subjected to very high pressure are typically than others because mineral grains are squeezed together, and the atoms are more closely packed. during metamorphic processes, water facilitates the transfer of ions between and within minerals, which can the rate at which metamorphic reactions take place. the growth of new minerals within a rock during metamorphism has been estimated to be about per million years. metamorphism is commonly associated with convergent plate boundaries, where two plates move toward each other. during contact metamorphism, a large intrusion will contain thermal energy and will cool much more slowly than a small one. metamorphosed sandstone is known as the metamorphic rock made from metamorphosed shale, was once used to make blackboards for classrooms
