Task - Today's Weather Report Introduction
Today you got to climb the mast and sit in the Crow's Nest looking for signs of land or other ships. You look ahead. You see a dark shape in the distance. You grab the spy glass to get a better look. Oh dear, there are storm clouds.
Soon, the waves grow bigger and it gets dark as the storm clouds rush toward the ship. You quickly make your way out of the Crow's Nest and back down the mast. The rain starts fall and the winds begin to pick up. You head below deck and into the study. The shortest route would be to sail through the storm, but the high waves convince you otherwise.
The Captain's Orders Read the log book The Atmosphere to learn about weather, climate, winds, and its impact on the oceans. You will need to use credible web resources. Review the EasyBib Finding Sources page for assistance in getting started. Make sure you clear document where you obtained your information and do NOT copy and paste the answer from a resource. Answer the
