Many individuals contributed to the creation of frozen food, but most credit goes to Clarence Birdseye.

Frozen food has always existed in climates that were cold enough for the food to freeze. Enoch Piper, William Davis, and Daniel E. Somes. invented innovative food-freezing techniques, however, Clarence Birdseye is credited with inventing in 1924 the quick freezing method, which produces the type of frozen foods that we know today.

While working as a fur trader in Canada, Clarence Birdseye discovered that the fish that he and the local Inuit caught froze almost immediately after being pulled from the water. He noticed that the fish was just as delicious when thawed out months later. From this experience, he theorized that food must be frozen very quickly in order for it to retain its taste and texture.

The Earth's axis is tilted. The temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!

During the summer, the sun's rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.
