6th Grade Interim Review

A student takes a bottle of cold water from the refrigerator and leaves it on the counter. Ten minutes later, the student noticed there is now water droplets on the outside of the bottle. Which scientific phenomenon explains the water on the outside of the bottle?

• Condensation because the temperature of the air nearest the bottle increased causing water droplets to form.

• Condensation, because the temperature of the air nearest the bottle decreased causing the water droplets to form.

• Evaporation, because the temperature of the air nearest the bottle increased causing the water droplets to form.

• Evaporation, because the temperature of the air nearest the bottle decreased causing the water droplets to form.

In science class, lab partners are designing an experiment that shows the important steps of the water cycle. For their experimental design, which of the following procedures could BEST be used to demonstrate the difference between condensation and evaporation?

• To show condensation, the lab partners must increase the temperature within the cycle; to show evaporation, they must decrease the temperature.

• To show condensation, the lab partners must maintain a constant temperature within the cycle; to show evaporation, they must increase the temperature

• To show condensation, the lab partners must decrease the temperature within the cycle; to show evaporation, they must increase the temperature.

• To show condensation, the lab partners must maintain a constant temperature within the cycle; to show evaporation, they must decrease the temperature.

Which statement best describes how the Sun affects the process found at X? 

• The Sun causes water to evaporate into the atmosphere where it forms clouds. Water falls from the clouds in the process of condensation.

• The Sun causes water to dissolve into the atmosphere where it forms clouds. Water falls from the clouds in the process of condensation.

• The Sun heats the air near Earth's surface. Condensation happens when water vapor condenses once it reaches the cooler air when rising. This process is responsible for the formation of clouds.

• The Sun causes water to evaporate into the atmosphere where it forms clouds. Water falls from the clouds in the process of evaporation.

• type of eggs

• amount of salt

• size of beakers

• amount of water

Part A: Which physical property is determined by the salinity and temperature of ocean water?

• density

• mass

• volume

• weight

Part B: Using the image, which area on the image will have higher salinity and why? 

• Area B, because it is closer to the poles with lower evaporation

• Area B, because it is closer to the poles with higher evaporation

• Area A, because it is closer to the equator with higher evaporation

• Area A, because it is closer to the equator with lower evaporation

The diagram illustrates that two types of currents are found in ocean waters. Which of the following is the best explanation for why oceans have two different types of currents?

• Surface currents are caused by wind whereas deep currents are caused by differences in density.

• Surface currents are caused by differences in density whereas deep currents are caused by wind.

• Surface currents are caused by temperature differences whereas deep currents are caused by changes in salinity.

• Surface currents are caused by changes in salinity whereas deep currents are caused by changes in temperature.
