Chico is examining two igneous rocks. He observes that one rock is light-colored and one is dark-colored. Both rocks have very large crystals and are very coarse. How can two rocks made by the same process be so different in color?

• They cooled at different rates.

• They contain different minerals.

• They were made at different times.

• They were worn down at different rates.

Aram made this model of the water cycle. What is the purpose of the bowl of ice cubes?

• The ice cubes hold the lid down so it does not rise during evaporation.

• The ice cubes melt as they are heated by the lamp to model runoff.

• The ice cubes keep the lamp from overheating the plastic lid.

• The ice cubes cool the lid so condensation and precipitation occur.
