Whales make noise to communicate, locate food, and find each other. Whales are very social creatures that travel in groups called "pods." They use a variety of noises to communicate and socialize with each other. Sound waves produced by whales can travel up to 3000 km (about 1800 miles) through the ocean. When would whale noises travel the fastest?
In the winter, when the water is colder.
In the summer, when the water is warmer.
All year round because water temperature doesn't matter.
When a whale jumps out of the water and calls through the air.
