Model Earth Lesson 3 Quiz

Describe how surface ocean currents move around the rotating Earth.

• Surface ocean currents, driven by snow and ice, move from the North to South pole during winter months
• Surface ocean currents, which are driven by winds and convection, follow a similar pattern to atmospheric convection cells.
• Surface ocean currents, driven by electricity, move from areas of high salinity to areas of low salinity

Iceland and Greenland are located at similar latitudes but have different climates. Use the model to choose the answer that best explains this phenomenon.

• A cold water current travels from the equator to Iceland. It does not travel to Greenland. This lowers Iceland’s air temperature
• A warm water current travels from the equator to Iceland. It does not travel to Greenland. This increases Iceland’s air temperature.
• A warm water current travels from Iceland to the equator. This increases the air temperature near the equator.
• Cold and warm water currents travel from the equator to Iceland. They do not travel to Greenland. This has no effect on air temperature.

Describe how this interaction affects Iceland’s climate.

• A warm ocean current travels from the Gulf of Mexico to Iceland. This warm water increases Iceland’s air temperature more than the temperatures in Greenland.
• A cold ocean current travels from Central America to Greenland. This cold water causes Iceland to have very hot temperatures since there is cold water nearby.
• A mild ocean current travels from Iceland to Africa. This mild current carries all the heart from Iceland to Africa making Iceland have colder temperatures than Greenland.

Monica and Tyrell plan to sail from Buenos Aires to Lima. They wonder what might affect their route. Monica looks at an ocean currents map for South America. The model shows the direction global ocean currents move. Monica remembers what happens when the currents reach land. Use the model to describe the factors that influence oceanic circulation. What do Monica and Tyrell need to know about ocean currents to plan their trip?

• Monica and Tyrell need to know the direction of the ocean currents that are on their route, or they could end up arriving somewhere that they didn’t plan since landmasses can change current direction.
• Monica and Tyrell need to know what other ocean currents exist on other continents, so they can plan for their trip after this one.
• Monica and Tyrell do not need to know anything about the ocean currents in this area since all of them move in a circular motion and will bring them back to land eventually

Julieta decides to make a model explaining how ocean currents circulate. She plans to make the model in a large, clear container. She fills two beakers with the same amount of water. Then she puts two drops of red dye in one of the beakers, and two drops of blue dye and a large handful of salt in the other beaker. She pours the red water into the large container and then slowly adds the blue water. What is most likely to happen?

• The water will turn purple
• The red water will stay on the bottom and the blue, salty water will float on top
• The blue, salty water will sink below the red water
• The red water will move to one side of the container and the blue, salty water will fill the other side.

Based on your answer for the previous question, explain why the result you chose will happen.

• The water is more dense than the fresh water from the other beaker.
• The water is less dense than the fresh water from the other beaker.
• The water is the same density as the fresh water from the other beaker.
