(Q).
Answer the following question given this paragraph: You've probably noticed dew on the grass on a summer morning. Why does dew form? Remember that the land heats up and cools down fairly readily. So when night comes, the land cools. Air that was warm and humid in the daytime also cools over night. As the air cools, it can hold less water vapor. Some of the water vapor condenses on the cool surfaces, such as blades of grass. The temperature at which water vapor condenses is called the dew point . If this temperature is below freezing, ice crystals of frost form instead of dew ( Figure below ). The dew point occurs at 100 percent relative humidity. Can you explain why?. Q: What is the name of the "point" that refers to the temperature at which water vapor condenses? Choices: - melting point - brine point - water point - dew point A:
(A).
dew point

Answer the following question given this paragraph: During metamorphism, a rock may change chemically. Ions move in or out of a mineral. This creates a different mineral. The new minerals that form during metamorphism are more stable in the new environment. Extreme pressure may lead to physical changes. If pressure is exerted on the rock from one direction, the rock forms layers. This is foliation . If pressure is exerted from all directions, the rock usually does not show foliation. Q: If pressure is exerted on the rock from one direction, the rock forms layers. this is called what? Choices: - protonation - stratification - sedimentation - foliation A:
foliation
