A scientific journal publishes articles about new findings in science. For an article to be published in a scientific journal, it must be reviewed by trusted scientists and found to be accurate. Which of the following reasons describe why is it important for scientists to publish their findings in scientific journals? 1. To show that their experiment is valid and other scientists did not find mistakes in it.
2. To help other scientists learn about their experiment and help them repeat it.
3. To ask for help from other scientists in forming new hypotheses.

(A) 2 only
(B) 1 and 2
(C) 2 and 3
(D) 1, 2, and 3

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.
