The picture shows a room with a ceiling fan and a fireplace. Heat from the fire warms the room. As fuel in the fireplace is burned, the fire gets smaller and then goes out. Then the air near the floor feels cooler. A person turns on the ceiling fan, and the air temperature near the floor begins to increase after the fan is turned on. Which of these best explains why the air temperature near the floor increases after the person turns on the fan?

• Fires produce more thermal energy when fan blades rotate.

• The rotating fan causes warm air near the ceiling to move throughout the

  room by conduction.

• The rotating fan pushes warm air that rose to the ceiling by convection back down into the room.

• Warm air from inside the room is drawn back into the fireplace when fan blades rotate.

How should the diagram be changed to accurately illustrate atmospheric convection currents?

• Add coral and fish to the water to represent energy flow.

• Add trees and bushes to the land to represent transpiration

• Add an arrow pointing up from the land to represent warm air rising and an arrow pointing down over the water to represent cool air sinking.

• Add an arrow pointing down over the land to represent cool air sinking and an arrow pointing up from the water to represent warm air rising.

A student pushed a toy car along a level track toward a spring. The car collided with the spring, causing the spring to compress. After the spring decompressed, the car traveled backward a short distance before stopping. Which statement accurately explains the energy transformation that occurred during the collision with the spring?

• As the car is compressing the spring, elastic potential energy in the spring is converted to kinetic energy in the car.

• As the car is compressing the spring, kinetic energy in the car is converted to elastic potential energy in the spring.

• As the spring is releasing, kinetic energy in the car is converted to elastic potential energy in the spring.

• As the spring is releasing, kinetic energy in the spring is converted to kinetic energy in the car.

The line graph shows the average air temperatures in a coniferous forest and a deciduous forest.

Which conclusion about deciduous forests is best supported by the data in the graph?

• Deciduous trees grow in areas with cold summers.

• Deciduous trees grow in areas with plenty of rain.

• On average, winters in deciduous forests are 30 degrees colder than winters in coniferous forests.

• On average, deciduous forests are ten degrees warmer than coniferous forests throughout the year.

A diagram of wind blowing up the side of a mountain is shown. The windward side of the mountain receives more rain than the leeward side. Which of these correctly explains why?

• Air cools, condenses, and gains moisture as it falls down the mountain.

• Air warms, condenses, and loses moisture as it falls down the mountain.

• Air warms, condenses, and gains moisture as it rises up the mountain.

• Air cools, condenses, and loses moisture as it rises up the mountain.
