Second Semester Midterm Review

Which of the following explanations describes how temperature and salinity affect the formation of deep currents?

• Decreasing the water’s temperature or increasing its salinity will cause water to become more dense. It sinks and becomes a deep current that moves along the ocean floor.

• Decreasing the water’s temperature or increasing its salinity will cause water to become less dense. It floats and becomes a surface current that moves along the ocean.

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 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 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.

Refer to the diagram above of a student’s lab setup of the water cycle. In this experiment, the total amount of water inside the container is measured at the beginning and then again after a full cycle has occurred. Which of the following best predicts the outcome of the experiment and explains why?

• The beginning amount of water in the container would be less than the ending amount of water in the container because the water evaporated, decreasing the water level.

• The beginning amount of water in the container would be more than the ending amount of water in the container because the process of condensation increases the water level.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated increased the water level but then came back as precipitation which decreased the water level again.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated decreased the water level but then came back as precipitation which increased the water level again.

At the seashore late in the afternoon on a hot, sunny day, a person often feels a strong breeze coming in from the ocean. Which of the following is the reason for the breeze?

• The warm air over the ocean rushes in to replace the cool air that rises over the land.

• The heavy, cool air over the ocean rushes in to replace the warm air that rises over the land.
