Put the events in the order that they would occur during a cold front.

• Heavy cumulonimbus clouds cause precipitation

• The warm air condenses to form clouds

• The cold air pushes the warm, moist air upward

• The warm air cools as it rises

Why would an air mass coming from Mexico have a warmer temperature than an air mass coming from Canada?

• Because Mexico is closer to the equator and generally has a warmer climate.

• Because Canada is closer to the equator and generally has a warmer climate.

• Because both Mexico and Canada have the same climate.

• Because air masses from Mexico are always cold.
