We live in an "ocean of air." The temperature of the air can vary from place to place. When the temperature is high we say the weather is "warm," when it is low, we say it is "cold."
There are several different ways the air in an area can change temperature. List at least two ways the outside air can become colder. Be sure to list specific causes. Discuss your list with your classmates.
