The weather map shows the weather for one day in the United States. Which of the following cities could most likely expect to see a rise in their temperatures in the next couple of days?

• Seattle, because a warm front should move through.

• Miami, because a cold front should move through.

• Dallas, because the High Pressure will trap the heat.

• Washington, because the rain will trap the heat under the rain.

Hurricanes are powerful tropical storms that develop over warm ocean water. Hurricanes draw their energy from the ocean and weaken as they move over land. Which of the following BEST explains how energy is transferred from the ocean to a hurricane?

• Evaporating water adds heat to the atmosphere.

• Rising tides change the level of the ocean surface.

• Waves cause turbulence in the lower atmosphere.

• Currents carry warm water along the ocean surface.

Two trains are traveling down a track. Train A has more mass than Train B. What will happen when the two trains attempt to stop with the same force at the Train Station?

• The train with the smaller mass will require less time to stop than the train with the larger mass.

  
  

• The train with the larger mass will require less time to stop than the train with the smaller mass.

  
  

• The train with the smaller mass will take longer to stop than the train with the larger mass.

  
  

• The train with the larger mass will have less inertia than the train with the smaller mass.
