[A]: When two plates of continental crust collide, the material pushes upward and forms what?

[Q]: Passage: Solutes change the physical properties of solvents. They lower the freezing point and raise the boiling point of solvents. Answer: solutes
[A]: What change the physical properties of solvents?

[Q]: Passage: Physical science, in turn, can be divided into chemistry and physics. Chemistry is the study of matter and energy at the scale of atoms and molecules. For example, the synthetic fibers in the swimmer's suit were created in labs by chemists. Physics is the study of matter and energy at all scalesfrom the tiniest particles of matter to the entire universe. Knowledge of several important physics conceptssuch as motion and forcescontributed to the design of the swimmer's suit. Answer: chemistry
[A]:
The physical sciences can be divided into physics and what other science?
