Answer the following question given this paragraph: Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum ( Figure below ). Q: What are formed when crystals precipitate out from a liquid? Choices: - diamonds - additive sedimentary rocks - gaseous sedimentary rocks - chemical sedimentary rocks A:
chemical sedimentary rocks

Answer the following question given this paragraph: Solid ionic compounds are poor conductors of electricity. The strong bonds between ions lock them into place in the crystal. However, in the liquid state, ionic compounds are good conductors of electricity. Most ionic compounds dissolve easily in water. When they dissolve, they separate into individual ions. The ions can move freely, so they are good conductors of electricity. Dissolved ionic compounds are called electrolytes. Q: In what state do ionic compounds best conduct electricity? Choices: - gas - solid - plasma - liquid A:
(Answer)
liquid
Ques: Answer the following question given this paragraph: Geologists look for oil in folded layers of rock called anticlines. Oil moves through permeable rock and is trapped by the impermeable cap rock. Q: What do you call the folded layers of rock where geologists look for oil? Choices: - oscillations - synclines - crests - anticlines A:
Ans: anticlines
