![]() When air moves across the ocean’s surface, it pulls the top layers of water with it through friction, the force of resistance between two touching materials moving over one another. ![]() Wind is a major force in propelling water across the globe in surface currents. Gravity pulls the water away from hills and toward valleys and Earth’s rotation steers the moving water. The Sun’s radiation creates prevailing wind patterns, which push ocean water to bunch in hills and valleys. (John James Wild, 1877)Īt the surface, currents are mainly driven by four factors-wind, the Sun’s radiation, gravity, and Earth’s rotation. This is a map ocean surface currents from 1877. Climate change is altering the processes that propel water across the globe, and should this alter ocean currents, it would likely lead to a cascade of even more change. While the ocean as we know it has been in existence since the beginning of humanity, the familiar currents that help stabilize our climate may now be threatened. This planetary movement has a strong effect on how oceans move. Though it appears we live on a stable and stationary planet, we are, in fact, whipping through space around the Sun in an orbit and spinning on an axis. It also requires a shift in perspective to encompass the movement of planets, the Moon, and the Sun. Ocean motion is influenced by occurrences here on Earth that are familiar, like heat changes and wind. ![]() Friction, drag, and density all come into play when describing the nature of a wave, the movement of a current, or the ebb of a tide. Ocean movement is created by the governing principles of physics and chemistry. Water is propelled around the globe in sweeping currents, waves transfer energy across entire ocean basins, and tides reliably flood and ebb every single day. But this is far from the truth-the ocean is constantly in motion.

She loved reading it after a day at the beach and had lots of fun associating her beach adventures with the little girl’s adventures in the book. We threw it in a beach bag to bring to her M’ma’s annual winter beach trip. We bought Wave when Ava was one, and she really enjoyed looking through the pictures. I would recommend this book for any age, infant and beyond. The publisher recommends this book for children preschool age and up. ![]() The story can be shorter or longer, you can go more in-depth about the little girl’s backstory, you can tell the story from the wave’s point of view, or the little girl’s, or the seagulls! I love how this fosters creativity (and prevents boredom from reading the same book over and over!) Age Recommendation Little things can change with each reading. You know the saying a picture is worth a thousand words, well, in wordless books a picture is worth a thousand stories. My favorite part about wordless books is how the story is different every read because you create it in your head. It’s refreshing to see humans take surprise situations as they come with peace and acceptance. Even when the wave gives the girl a surprise splash, she takes it in stride, and instead of getting upset is able to discover all the beautiful seashells that the crashing wave uncovered. The feeling of Wave takes you back to a time of childhood with negligible worries or cares. The experienced seagulls on each page are an indicator of when it’s time to run away from the wave or you’ll be sorry! I do appreciate how this book is not afraid of showing kids the power of the ocean. The little girl and wave go back and forth, playfully teasing and taunting. The waves in this book are almost a character of their own. The story is about a little girl’s trip to the beach with her mom and revolves around the joyful interaction between the ocean waves and the girl. ![]()
