What happens when a warm air mass meets a cold air mass?

• The warm air sinks below the cold air

• The cold air rises above the warm air

• The warm air rises above the cold air

• They mix evenly

Which of the following is a characteristic of a stationary front?

• It brings sudden temperature changes

• It remains in the same place for a long time

• It causes hurricanes

Why does warm air rise and cool air sink?

• Warm air has higher density, so it floats above cooler air.

• Warm air is less dense than cool air, causing it to rise.
  

• Cool air evaporates, pulling the warm air upward.

• Cool air generates more energy, pushing warm air up.

• It often leads to stormy weather

• It causes temperatures to rise significantly

• It results in dry conditions
