Air and Water Currents

A student creates a model to show how the sun affects ocean currents. If this correctly models ocean currents, where will the heated water go?

• It will sink to the bottom of the tank.

• It will concentrate under the heat lamp.

• It will spread out evenly in all directions.

• It will flow along the surface away from the heat lamp.

Town X is in a coastal area near the equator. What effect will the ocean have on the climate of town X?

• Town X will likely experience more tropical storms than inland towns

• Town X will have lower average annual temperature than inland towns farther from the equator.

• Town X will experience great extremes in weather because of the temperatures at day and night.

• Town X will likely have large amounts of snow due to increase condensation over the ocean.

Which feature could be added to the model to represent evaporation?

• a small stream of water flowing downward at an angle

• a garden showing the releaseddd of water vapor into the air by plants

• a decorative fountain overflowing with water as raindrops fill its basin

• a small, drying puddle as the sun heats the water and changes it to water vapor

The diagram shows ocean currents near South America. Which describes the effect of the oceanic current eat of Brazil?

• Heat flows from B to A, causing the weather and climate in the region around A to be unusually warm throughout the year.

• Warm water flows from B to A, causing the weather and climate in the region around B to be unusually warm in the summer.

• Thermal energy flows from B to A, causing the weather and climate in the region around B to be unusually cool in the summer.

• Cool water flows from B to A, causing the weather and climate in the region around A to be unusually cool throughout the year.

Jill used an aquarium filled with salt water to make a model of ocean currents. Which component should Jill add to the model to help demonstrate a major factor in global ocean currents!

• algae to show how photosynthesis causes changes in water density

• fresh water mixed with food coloring to show differences in density

• saltwater fish to show how the movement of animals causes the movement of water

• a spray bottle of salt water mixed with food coloring to show how rain causes movement of water

Which events are examples of energy transfer or energy transformation? Write the letter of each event in the correct box.

• Kinetic wind energy forms waves on the surface of the water belongs to energy transformation and Thermal energy in the air becomes kinetic energy of wind belongs to energy transfer

• Kinetic wind energy forms waves on the surface of the water belongs to energy transfer column and Thermal energy in the air becomes kinetic energy of wind belongs to energy transformation column

• None of these fit in either column

• Both fit for both columns
