What is an air mass?

• A large body of water with relatively uniform temperature, humidity, and pressure characteristics.

• A small body of air with relatively uniform temperature, humidity, and pressure characteristics.

• A large body of air with varying temperature, humidity, and pressure characteristics.

• A large body of air with relatively uniform temperature, humidity, and pressure characteristics.

What is air pressure?

• The force exerted by the weight of water molecules in the Earth's atmosphere.

• The force exerted by the weight of soil particles in the Earth's atmosphere.

• The force exerted by the weight of gas molecules in the Earth's atmosphere.

What happens when a warm front meets a cold front?

• The cold air rises above the warm air and forms clouds and precipitation.

• The warm air rises above the cold air and forms clouds and precipitation.

• The warm air and cold air mix together and form clouds and precipitation.
