The early explorers relied solely on wind power and were able to travel around the world! Christopher Columbus sailed 5,400 miles from the Canary Islands to the Caribbean in 36 days. How was this possible? Wind.
WESTERLIES AND EASTERLIES
The area between about 30º and 60º latitude is known as prevailing westerlies because the wind comes from the west (winds are named for the direction they come from). In the area above 60º the cool air over the poles flows south and because of the Coriolis effect. It curves toward the west from the east so they are known as polar easterlies.

I often struggle to find websites with thorough explanations in simple language to help kids understand historical events or scientific concepts, so I decided to create some of my own!
