Today in class Doc. Gruninger and Mr. Kirby enlightened us with a lesson focusing on waves, currents, and tides in the oceans. The lesson was very worthwhile, and I feel like I learned a lot today. This lesson really fit in well with the overall aim toward learning more about Marine Biology. The waves, tides, and currents all influence the marine life and the different organisms in the oceans. These different marine phenomenons in the oceans changes the habitats and lives of many animals, and these phenomenons change the weather around the world.
