Air over land changes temperature at a different rate than air over water. Which statement best describes how this difference causes wind?
The warmer air over land rises as cooler air over water takes its place.
The cooler air over water moves toward land to mix with the warmer air.
The cooler air over water rises and the warmer air over land sinks.
The warmer air over land moves toward the water, forcing the cooler air to rise.
Which statement best describes the type of water carried by the Norwegian Current as it moves from the tropics toward the North Pole?
The water is warm and near the surface.
The water is cold and dense.
The water is cold and comes up to the surface.
The water is warm and deep.
Which statement best describes the movement of the ocean currents?
Warm currents start flowing at the poles.
Cold currents start flowing at the equator.
Cold currents tend to flow under the warm currents.
Warm currents tend to flow deeper than cold currents.
The Gulf Stream current is found in the Atlantic Ocean and flows from the tropics to the northern latitudes. Which best explains the movement of the Gulf Stream current?
The warm current is more dense and pushes cold waters toward the equator.
The warm current flows toward the poles where it cools and sinks.
The warm current contains an electrical charge that is attracted to the magnetic poles.
The warm current contains sediment that is heavier than cold currents and pushes them downward.

A student rubs a metal coin against a rock and notices the coin becomes warmer. Which best describes this energy transformation?
mechanical energy to heat energy
electromagnetic energy to chemical energy

A toy car has a metal spring inside that can be wound. As the spring unwinds, it moves the wheels, causing the toy car to roll forward. How does this demonstrate the law of conservation of energy?
The mass of the spring stayed constant, so its energy also stayed constant.
The mass of the spring changed when wound, so the energy of the car changed.
The energy in the spring increased as the motion of the car increased.
The energy in the spring was transferred to the car, causing it to move.
